A coil, and the multiple coil can be by the switching device that multiple switch forms to change the connection in series-parallel shape of the multiple coil
State makes electric vehicle not only have high endurance optionally to adjust motor performance between power saving effect and torsion and rotating speed, and
Can also there be splendid efficiency in the occasion for needing high output.
Also, embodiment according to the present utility model, permanent-magnet motor apparatus can change multiple lines of winding by switching device
The connection in series-parallel state of circle makes motor performance can be between rotating speed and power saving effect demand to adjust the rotating speed and power saving effect of motor
Transformation, greatly improves the efficiency of motor.
In addition, embodiment according to the present utility model, permanent-magnet motor apparatus can change each winding by switching device
The connection in series-parallel state of multiple coils will not increase volume and again to adjust the rotating speed and power saving effect of permanent-magnet motor apparatus
Amount, therefore do not interfere with the design of electric vehicle.
In addition, embodiment according to the present utility model, permanent-magnet motor apparatus can be applied to various types of Permanent Magnet and Electric
Machine, such as DC brushless motor and brush direct current motor, therefore apply upper extremely wide.
Furthermore the structure design of embodiment according to the present utility model, permanent-magnet motor apparatus is simple, therefore can be little
Width reaches the effect of to be reached in the case of increasing cost.
It can be seen that the utility model has reached the effect of to be promoted, and art technology really in the case where breaking through the prior art
Personnel do not allow progressive, the practicability for being readily conceivable that, having yet, and the aobvious application important document for having met patent proposes patent Shen in accordance with the law
Please, earnestly ask that your office checks and approves this part invention patent application case, to encourage innovation and creation, until sense moral is just.
The foregoing is merely illustratives, rather than are restricted.Other any spirit and scopes without departing from the utility model,
And the equivalent modifications that it is carried out or change, it should be contained in appended claims.
