Tool, it has as running driving device and/or equipment, the especially drive device of working hydraulic pressure device synchronous magnetic
Motor is hindered, wherein, the synchronous magnetic resistance motor has stator and rotor, and the stator is used to produce provided with least three phase windings
Rotating field and the stator body being made provided with the soft magnetic materials by high magnetic conductivity as stator material, the rotor has is led by height
The rotor block that the soft magnetic materials of magnetic is made as rotor material.
Background technology
Known in the prior art so-called synchronous magnetic resistance motor, these synchronous magnetic resistance motors are to be used for the operation of 4 quadrants
Three phase electric machine (Drehfeldmaschine), wherein, the three phase electric machine can be used as motor or generator to implement and run
And implement and run in both rotational directions respectively.
In the three-phase motor observed as an example, compared with asynchronous machine, in synchronous magnetic resistance motor, stator winding point
Do not arranged with staggering with 120 ° of electricity, wherein, each phase is provided with a stator winding.
Apply relative to the rotor or rotor by the special shaping with notable magnetic pole of rotor or rotor
The strong preferred orientation in magnetic field.Rotational motion is produced by the magnetic of rotation, and rotor attempts to follow the magnetic of the rotation
.In stable operating point, stator correspondingly synchronously follows stator rotating field (Stadttordrehfeld) and stator revolves
Transition is on stationary rotor.Rotor is thus through-flow by permanent field, and the alternating field magnetization in stator experience cycle.Relative to asynchronous machine
Or by permanent magnet come the synchronous motor of excitation, wherein, torque passes through with the magnetic field alternation of the electric current flowed through a conductor
Effect is produced by being acted on the alternation of permanent magnet, and the torque in reluctance motor, which produces to be based on being applied in magnetic field, to be turned
Maxwell force (Maxwellschen Kraft) on the soft magnetic substance of son is carried out, and passes through the Maxwell force, magnetic
System pursues the state of minimum magnetoresistive or magnetic resistance.The motion is passing through stator coil stator winding institute in other words by rotor
Orientation on the magnetic field of generation realizes, wherein, by the sensing of appropriate 3-phase power converter and the stator coil couple come
Produce the magnetic field rotated.
With in the stable operation in the case of constant rotating speed and constant torque by the through-flow rotor in a permanent field on the contrary, fixed
The alternating field magnetization in sub- experience cycle, alternating field magnetization can produce so-called iron loss, the iron loss by magnetic hystersis loss and
Eddy-current loss is constituted.The remagnetization that the magnetic hystersis loss passes through the molecular magnet (Elementarmagnete) in stator material
(Ummagnetisierung) acting in the case of is produced.If the magnetization of stator material is applied by magnetic field strength, that
Produce a typical curve map, also referred to as hysteresis curve, it is on the integral representation of area that surrounds for the acting
Measure, it is necessary to the remagnetization done work for the molecular magnet in a remagnetization cycle.Here, magnetic hystersis loss into
Ratio is in the frequency of the remagnetization, therefore the frequency of the electric current in the case of the stator in proportion in stator winding.
The second component of iron loss is eddy-current loss, the eddy-current loss as due to magnetic induction in stator material caused by
The heating by Ohmic resistance of vortex.The eddy-current loss this quadratic power and frequency dependence, thus equally with observation
The frequency dependence of manipulation stator winding in the case of stator.Therefore, the formation stator of stator winding it is metal-cored frequently
Implemented by the accumulation of multiple sheet materials for being expressed as electrical sheet.Structure Shangdi is attempted by the layering of the stator material
Reduce eddy-current loss.Here, relative to each other for example by the segregate electrical sheet of coating on flow direction so that perpendicular to
Vortex direction is stacked.

Segmentation method is manufactured.For example by the segregate electrical sheet of dipping lacquer be next stacked as stator core and rotor magnetic core and
Mechanical Shangdi is connected to each other.Therefore electrical sheet for rotor and stator is same quality and thickness.
In the prior art disadvantageously, thus, the reduction of the iron loss in stator material and simultaneously in rotor material
The optimization of magnetic resistance only can difficulty be realized.
In addition it is well known that, in order to reduce conductive capability and thus eddy-current loss and by the ferromagnetic material alloy provided with silicon part
Volume.
But in the prior art disadvantageously, the silicone content negatively influences the magnetization of iron, its mode is, magnetic pole
Change J as increased silicone content declines, that is, return to magnetic resistance.Thus magnetic is caused to pass on the contrary with the reduction of eddy-current loss
The deterioration for the property led.
Substitute direct current generator and use threephase asynchronous machine as the electric pump motor of working hydraulic pressure device, or also
Also three-phase permanent body synchronous motor is used in the case of higher power requirement, if there is higher than requirement to direct current generator
Requirement if.Relative to direct current generator, three-phase synchronous motor or threephase asynchronous machine are simpler in structure and exempt from dimension
Shield, because converter is eliminated, and their characteristic is higher efficiency.Especially in working hydraulic pressure device with three-phase synchronous
In the case of the pump motor of motor or threephase asynchronous machine as electricity, a steering hydraulic device is at least integrated into the work
In hydraulic means.
But disadvantageously, relative to direct current generator, because required, in check three-phase rotating field, actuation means are bright
It is aobvious more complicated, since it is desired that the detection of position state or velocity of rotation and corresponding power electric device.
As the running driving device of ground conveying machine and for equipment, especially working hydraulic pressure device
Drive device uses d.c. motor or threephase asynchronous machine mostly, and three-phase permanent body is also used in the case where power requirement is larger
Synchronous motor.Synchronous magnetic resistance motor in contrast has high power density and compact size, but with higher damage
Wasted work rate.
