There is strip groove in the middle part of the lateral surface of salient pole, the strip groove is through to other end from the end face of salient pole.By with
Upper groove designs so that a salient pole can have two numbers of poles, and the operational efficiency and cost for being advantageous to improve motor are reduced.
In above-mentioned switched reluctance machines, the mounting hole site is in the bottom of strip groove.Design, avoid more than
Opening up for mounting hole impacts to the magnetic circuit of motor.
In above-mentioned switched reluctance machines, the salient pole at least has two and is distributed on outer turn along the circumference of outer rotor
On the inwall of sub- iron core, stator core is provided with the outer rotor iron core, is provided with the stator core corresponding with salient pole
Winding coil.According to being actually needed, the quantity of the number of poles of outer rotor and the winding coil of stator can be flexibly selected.
In above-mentioned switched reluctance machines, the mounting hole is screwed hole or rivet hole.According to the type of mounting hole,
Fastener can select screw or rivet.
In above-mentioned switched reluctance machines, there is ending cover hole on the end face of the outer rotor iron core.Designed more than,
It is easy to electric motor end cap to install.
Compared with prior art, this switched reluctance machines has advantages below：This motor passes through to the salient pole on outer rotor
Structure is improved design so that the process time of this motor and processing cost are obtained for reduction, and improve the fortune of motor
Line efficiency.
