Embodiment Construction
[0026] exist figure 1 , 2 , 3A, 3B to Figure 5A , 5B Among them, the present invention is a device that can increase the speed of a permanent magnet motor, which includes:
[0027] A permanent magnet motor 11, which includes a stator part 21 for the excitation coil 211 of the winding type. The stator part 21 also has a slot seat 212, a positioning device 213, a circuit board 214, etc., and multiple sets of magnetic sensors can be provided. 41 The fixed device also includes a permanent magnet rotor part 31, which contains a rotating rotor with permanent magnets. The rotor part 31 is pivotally connected to the stator part 21 with a rotating shaft 311, and corresponds to the stator part 21, and the armature reacts to rotate magnetically ; There is also a motor drive control circuit 61 for controlling the permanent magnet motor 11.
[0028] A plurality of sets of magnetic sensors 41 are arranged on the stator part 21 at various angles, and sense the rotation changes of the pe...
