Description of the invention (1) Background of the invention The present invention relates to a switched reluctance motor (Switched reluctance bo tor, or SRM), especially a type of _control or control motor, which reduces the motor noise. Method. It is well known to change the magnetic sister Yuda or SRM. _Yinwei is an inter-molecular of these motors. As discussed in the pending patent application Shenyong Case No. 08 / 175,268, one source of this type of sound is the current consumption in the phase of the motor at the end of each cycle at the end of its cycle. Caused by scattered. When the motor is switched from one phase to another phase, it means that the energy supplied by the phase winding during the active phase is about thirty percent (30 «) of the energy. As stated in the application, one part of this curtain volume is either recovered from the electricity storage container or dissipated. In general, please understand that the main reason for the malyanzine sound is the sudden change of normal force experienced by the bungee. If the maximum instrument in the Yu Fiber Circulation is sticking out of any regulations, any such passages * the noise house is particularly sharp. In US Patent No. 5,239,127 of Shenlianren, a phantom called "mechanical drying" was described. This is the force generated when the rotor pole and stator® pole are aligned. This makes the motor generally circular rotor and The stator is deformed into a shape of 钃 _ shape. These earlier application cases also explained the technology that can minimize the force of these 钃 circles. I understand the method described in my earlier application of Li although Effectively extinguish the low motor _ sound • But other efforts to further extinguish the low horse scorn are also important. Control by using M to dig the current and M to minimize the torque (See US Patent No. 4,868.477 granted to Anderson et al.)

CUn and HR Bolton in their paper“ Performance Enhancement of Single- Phase Switched Reluctance Motor by DC Link Voltage Boosting "; IEEE Proceedings-ft, Volume 140, Paper H 0. 5, September 19, 3rd, discusses the third design of Lun. The flow enters a phase, and then starts and breaks in a phase; the auxiliary rib voltage is used, and M is removed faster than normal. One of the disadvantages of this method is its lack of flexibility. Although M above The methods may be effective > but it requires a large circuit * or a large amount of manipulation to achieve a reasonable amount of control. Other methods of Erliu painting can be more effective and easier to achieve. It is important to understand, to At the end of the active part of a phase, the slope of the current pattern may closely match the slope of the circular current tail reduction part. The # sound reduction is achieved by Μ. In the inventor ’s pending application 08/1 No. 75/268 > It was revealed to control the tail current Apparatus and method of reduction. According to the disclosure, the slope of the _type 颔 _ part can be controlled. Using the disclosed method and method * can control the phase active part of the pattern, so the rule can be relatively flat Called the transition, without affecting the period of the phase or other important masculine exercises, M achieves a reduction of 41 sounds. SUMMARY OF THE INVENTION The object of the present invention is to provide a SRM or multi-phase SRM, such as 2-phase and 3-phase SRM such as 12-6, 2-phase SRM and 6-4, 3-phase SRM for each phase, to manipulate the current pattern Control design and method; provide this control design and method (please read the back-end notes before filling out this page) „~ I 丨 Binding on line V.

According to this drawing, current flow initially increases rapidly from zero to a peak when the phase becomes active, and then allows the current to decrease from this peak to a second and smaller value when the phase becomes inactive. When the phase becomes inactive, the current will decrease from the second value to zero. The transition of the current pattern that occurs when the phase is switched from active 1 to non-active is no longer a sudden transition • It is more modest. This relatively flat transition reduces the amount of noise that the motor usually produces when the flow stops and flows into the winding. This reduces the motor noise. This case also reveals a method of controlling the current pattern. Many other objects and features of the present invention are partially visible, and some will be dragged out below.

Refer to Figures 4A, 4B and 5A, circle- The representative current pattern P 1 * K of the motor phase and the normalizing force generated in the motor. In No. 4 B, the circle shows zero current before the specific phase connected by the winding becomes active. The phase is at zero amperes. Time To becomes active. Thereafter, until time Tc, the winding is supplied to the phase winding. At time Tc, the phase becomes inactive, and the current flow to the winding stops. From time Tc until time Tf · The current value decreases back to zero When the current starts to flow into the phase winding, the current level usually rises to the level IP and reaches this level at time Tx. From time raTK until time τ〇> the current flowing into the scale group is fixed and kept at Erping Ip. At the time Tc, when the flow stopped flowing into the Neng group, there was a sudden transition in the slope of the flow pattern. This is because the current was quickly moved to Lei at the time Tc as shown by the slope of the fatigue spike on the current pattern. _4a shows the winding pattern Li of the winding W and shows the current flowing in the winding According to the circular shape of FIG. 4B, the sense of the phase is supplied to the phase. As shown in _5A> The normalizing force circle type F 1 of the motor also shows a sudden transition at the current cut-off time T. Normalizing force type The result of the sharp change in the slope above is the loud whistle represented by the wave yarn V 1 in Figure 5 A. This whistle reverberation produces a high volume in the motor. This type of volume is undesirable. Produces such as 圔 4D The "Plug-in-Plug-type" shown in Figure 2 is a feature of the circuit 10 and the method of the present invention. According to this method, when the phase becomes active, the current flow into the winding increases rapidly from zero to a sharp peak IP '. As shown in Off 4D, the current between To and Tx is moved to this peak value. Since time T X and then allowed, Xu Lei flows in phase and becomes inactive at time l c from this peak value to as little as one The second and smaller value, for example, the current level I Ρ. The current is then applied according to the standard. _ Jia Biao Ping (CNS) Λ4 present grid (21 () _ /: 2 |) 7 male male) Ministry of Economic Affairs A7 B printed by the Beigong Consumer Cooperative of the Central Bureau of Standards. 5. Description of the invention (8) The second value has since been reduced to zero when the phase becomes inactive The advantage of controlling the current pattern in this way is that the slope of the current pattern between time Tx and time Tc is no longer the actual leveler as shown in the typical situation of FIG. 4B. Instead, the current has a slope (negative slope) that is in phase with the slope of time T X to time T f (negative slope) • but the slope is not as sudden as it is. When the current supply to the phase stops at time T c, the transition on the current pattern of the output is not a sudden transition * but a softer or more stable encounter ii. Circle 5 B shows that when the flow is supplied to a phase according to the circular P 2, the normal force pattern P 2 of Mayang is shown. In this figure, this more stable transition reduces the motor speed when the current stops flowing around the sister. Out of regulation W sound volume. The waveform V 2 in FIG. 5B shows this situation. As shown in the picture, the resulting motor_sound is significantly reduced. As mentioned above, the circuit 10 of the present invention includes a P W M signal generator that supplies operating signals to r or both of the dark channels S 1, S 2. Or, as shown in Figure 2, Kanlu 1 utilizes a micro-processing module, which has a P W M signal that also provides an operation multiple to Kang Kan. The signal generator I 6 or the microprocessor 20 can be supplied with a P W M signal which is a “soft” off 0 signal, or a “hard” off signal. _ 3 Α shows the soft break, read signal, draw 3 Β shows the hard break signal a If the signal generator or micro processor is supplied with a soft break if. Signal, this signal is supplied to the switch-for example, open S 2 , K will adjust Kai Kan between his "quote" and "醐" positions. On the other hand, the active part of the phase S 1 is kept in a fixed " off " state. On the other hand, if the signal generator or the micro processor supplies a hard-break signal, it also appears to be the same as the second open threshold. Please refer to _4C, _ shows a PWM signal G1, which is supplied to a phase group according to the flow pattern P 1. The signal G 1 is the entire & scale of the valve from time To to time Tc.

A 7 B7 V. Description of the invention (9) The phase active interval has a fixed frequency and duty cycle. The average pressure curve A1 shows the PWM waveform supplied to the phase at the phase active interval The average voltage is shown as a fixed value throughout the interval. To obtain the current pattern P2 in accordance with the purpose of the present invention, the PWM signal or signal G2 supplied to the winding can be controlled in several different ways (see FIG. 4E) ^ In circle 4E, the operation signal is shown to have a fixed frequency, but a variable duty cycle. Therefore, as in surface 4E See, from time To to time Tx, the operation signal has a working cycle • It starts at a first value and then gradually becomes shorter throughout the interval. However, this working cycle is shorter than the time T 0 to time T X is supplied to the The duty cycle of any operation signal of the switch or the two-off. Now, the average voltage curve of the PWM signal i supplied to the phase in the active part of the phase is shown as: First segment * where the average voltage is actually greater than the second Segmentation. The wine segmentation corresponds to the individual intervals of the variable and fixed duty cycle PW M signal supply to this phase. This situation is important because it means that the current is driven to the desired peak current at time T X The average value of the input from Ip 'to this phase must be higher than those supplied otherwise. Refer to Figures 7A-7C, and Figure 7A shows a PWM signal flow corresponding to the one shown in circle 4E. According to this design, from time To to T X, the working cycle of operating the double number is initially at a first value, and then gradually becomes shorter. From time Tx to Tc, the operating signal has a fixed I cycle, which is shorter than From time Τ 〇 to T > supply Open the duty cycle of any operating signal of the device. In circle 7 B, an alternative way of achieving the same result is that the first part of a phase active interval is supplied with a significantly higher pressure to that phase, including the supply A PW M signal with a definite working cycle but a variable frequency. The frequency starts to be a fixed frequency. The size of this paper is suitable for fff t valves.

V. Description of the invention (10) It gradually becomes higher from the interval To to Tx. Since time TXg Tc, the operating signal has a fixed frequency, which is higher than the frequency of any operating signal supplied from the time To to the TX supplied to the shut-down device. Finally, in the E7C, a third method of supplying a significantly higher voltage to the phase in the first part of an active interval of a phase includes a PMM signal with variable duty cycle and variable frequency. No matter how the frequency of the signal and the duty cycle change the interval To to Tx * from time Tx to Tc, the operation signal has both a fixed frequency and a fixed duty cycle. What has been described is a control design and method for manipulating the current pattern for each phase of Mkai or multi-phase SRM. The circuit that implements this circuit design controls the current shape in the active part of each phase to reduce motor feeding. The circuit and method can use hard-breaking or soft-breaking current control technology, and M controls the current pattern. During operation, the current level is driven to a peak amplitude that exceeds the current normal drive. Then when the phase becomes inactive • Allows the current to drop from its peak to the same current level as the current normal . The result is that when the phase becomes inactive * the slope of the current sperm type is changed less suddenly than it would otherwise be. The IS control design and method can be easily integrated into the conventional SRM control hyoun, and may include a microprocessor. According to this method, a duty cycle of a P W M signal is used to control the flow of current in the phase winding when the phase is active. Box W initiates during the active phase of the phase * to quickly drive the current to its peak amplitude. Or then * change the frequency of the PWM signal to achieve the same result. You can also change the working cycle and the frequency of P W M * M to achieve the same result. The advantages of this control design and method are: • To modify the normal force in the motor, so that when the phase reaches from the active to the non-primary, the normalized elliptical force acting on the motor changes less suddenly, thus extinguishing the low Ma Yun J: Zhimu paper degree.
