Embodiment

Embodiment 1:

Referring to Fig. 1, Fig. 2, present embodiment mainly is made up of protecgulum 1, bonnet 2, circuit control device 9, rocking arm 3, wire spring 6, display floater 7 and corner motor 8.Corner motor 8 is fixedly mounted on the bonnet 2.Also be vertically installed with a rocking arm 3 in corner motor 8 rotary shaft end, can be connected with extraneous load by rocking arm 3.The velocity ratio of angular velocity and output rocking arm angular velocity is 1 on the corner electric machine main shaft in the present embodiment.

Referring to Fig. 3, Fig. 4, Fig. 8, corner motor 8 in the present embodiment is mainly by front cover 8-1, rear end cover 8-2, and motor shaft 8-3, rotor 8-4,, motor stator 8-5, staor winding 8-6 and motor down-lead are formed.Motor shaft 8-3 is installed with motor stator 8-5, and axle 8-3 passes rotor 8-4, and by two end cap 8-1,8-2 supports, and make rotor be enclosed within on the motor stator, and motor shaft can be with motor stator to do together freely to rotate.Motor stator 8-5 is provided with winding 8-6, and stator embeds two end cap 8-1, and among the 8-2, stator 8-5 is made up of four utmost point 8-7, and angle is 90 ° between each utmost point.Two every adjacent utmost point 8-7 on the stator 8-5 are around a coil, and relative two coils are connected into a winding.A total winding C on the stator in the present embodiment, two windings of winding D, the axis of two winding C, D is mutually 90 °.

Add VDC Uc on the winding 8-6-C of motor, just have electric current on the winding 8-6-C and flow through that according to right hand rule, then the direction in the magnetic field of Chan Shenging is will be on the axis of winding 8-6-C, its direction is positive and negative consistent with voltage.In like manner, add identical voltage on winding 8-6-D, then the magnetic direction of Chan Shenging also can be consistent with the axis of winding 8-6-D.Because two winding axis are mutually 90 °.So the direction in two magnetic fields also is mutually 90 °.The parallel four limit row rules synthetic according to vector, two sizes are identical, and the resultant vector of the vector that direction is vertical should be on their angular bisector, and size is 2 times a evolution of single vector.If 8-6-D adds alternating voltage with winding, the voltage polarity reversal on winding 8-6-D once, the direction in the magnetic field of corresponding generation also can be changeed 180 °.At this moment the voltage of winding 8-6-C is constant, and the direction of both Resultant magnetic fields can half-twist.As can be known, as long as the continuous conversion of polarity of voltage of winding 8-6-D, the Resultant magnetic field direction will be to beat in 90 ° the scope back and forth so.So the direction of rotor can be along with changes of magnetic field, corresponding axle is also along with rotation angle is also done corresponding variation.But turn over 90 ° of not further commutations of Resultant magnetic field at rotor, so rotor can only stop with rear motor.

Circuit control device 9 mainly is made up of supervisory keyboard 10, display floater 11, processor 12, corner motor-drive circuit plate 5 and position transducer 4.The circuit board of position transducer 4 is installed below bonnet 2.Installation of driver control circuit board 5 on protecgulum 1, and the control knob in the driver control circuit plate 5 after installing is exposed to the outside of protecgulum 1.
