Description
Technical field
The present invention relates to a kind of motor, need to detect the motor of its turned position in especially using, also relate to a kind of digital light processing formula projector that comprises for the motor that drives colour wheel.
Background technology
In many electronic equipments that comprise motor, such as comprising for the floppy disk of the motor that drives floppy disk and comprising for the digital light of the motor that drives colour wheel and process formula projector, all need to detect the turned position of motor.For example, disclose a kind of motor in Chinese patent literature CN1179344C, wherein detected the position of rotary body by the flux that adopts inductor detection rotor magnet.As shown in Fig. 1-2, the rotor yoke iron 3 of this motor is shaped as the more shallow cup of overall depth, is provided with integratedly flange 3a on its periphery, is formed with the nick shaped hole 3b of section of Rack on the part of flange 3a.In addition, on rotor yoke iron 3, running through wherein, heart is equipped with axle 9.Rotor magnet 8 was sticked on the interior week of flange 3a with circularizing endless, and became the S utmost point-N utmost point according to all-round decile mode alternating magnetization, and the logical via portion 3b of the part of rotor magnet 8 is exposed at the outside of rotor yoke iron 3.As shown in Figure 3, be provided with inductor 7 near the periphery of flange 3a.Thereby, when the rotor yoke iron 3 of motor rotates, along with this rotation, logical via portion 3b and the rotor magnet 8 that exposes rotates equally, it the time and leave inductor 7, the time and near inductor 7.When the rotor magnet 8 near the hole 3b of section leaves inductor 7, because inductor 7 does not receive the flux of rotor magnet 8 fully, so the induced voltage of inductor 7 is zero; And when during near inductor 7, receiving the flux of rotor magnet 8 near the rotor magnet 8 of the hole 3b of section due to inductor 7, so the induced voltage of inductor 7 be and the proportional value of flux time variation.By inductor 7 is carried out suitable processing with the flux detection output valve of voltage form output, just can obtain the index signal of revolution subsequently.
Yet have following technical problem in the motor of above-mentioned prior art: owing to being provided with the hole 3b of section on rotor yoke iron 3, the flux of rotor magnet 8 spills (1), and motor characteristics can worsen; (2) when interior week of the flange 3a that rotor magnet 8 is fixed on rotor yoke iron 3 is upper, due to can not be at the all-round coated with adhesive of the outer peripheral face of rotor magnet 8, so can produce more vibration and noise; (3) when carrying out the assembling of rotor magnet 8 and rotor yoke iron 3, need to indicate the boundary part of magnetic pole and the boundary part of the magnetic pole of rotor magnet 8 is exposed from the hole 3b of section on rotor magnet 8, thereby cause operating efficiency low.
Therefore, be badly in need of a kind of motor that can address the above problem.
Summary of the invention
An aspect of of the present present invention just is to provide a kind of motor that can solve one or more the problems referred to above.Motor of the present invention comprises rotary body and meront, this rotary body comprises the rotor retainer with cylindrical lateral wall and top cover, this meront comprises magnetic position testing agency, it is positioned at around the rotor retainer, position of rotation for detection of the rotor retainer, wherein this rotary body also comprises a magnet unit on the sidewall radial outside that is arranged on the rotor retainer, and this magnet unit has two different magnetic poles of polarity and a magnetic pole boundary section between described two magnetic poles on Zhou Fangxiang.Because the sidewall of the rotor retainer of motor of the present invention is not provided with hole section, can prevent because of dust deposit in the inner operation that affects motor of rotor retainer, the vibration that has produced when having reduced motor operation and noise also make the assembly technology of motor oversimplify, thereby enhance productivity.The coating of binding agent and the assembling of rotor magnet become easily, and the flux of rotor magnet can not spill from hole section, and this has improved the runnability of motor.In addition, have two magnetic poles due to magnet unit on Zhou Fangxiang, reduced the switching position of magnetic pole.
Another aspect of the present invention provides a kind of digital light to process formula projector, and it comprises the motor described in foregoing embodiments, also comprises the colour wheel that is driven by this motor.Be arranged on the radial outside of the sidewall of rotor retainer due to magnet unit, a color boundary section of the magnetic pole boundary section that is easy to make magnet unit and colour wheel roughly aligns on Zhou Fangxiang.
