Description
Technical field
The utility model relates to the adjustable disc type electric machine of a kind of air gap.
Background technology
Disc type electric machine comprises stators and rotators, and stator is arranged on flat substrate, and rotor cover is on stator, and usually, stator is coil, and rotor is permanent magnet or the disk being stained with permanent magnet, and disc type electric machine is widely used due to characteristics such as its quality are light, structure is thin.
Air gap refers to the air gap existed between motor stator and rotor, the efficiency of cutting magnetic induction line when the size of air gap value can affect electric motor starting moment of torsion and run.Air gap is crossed senior general and is caused motor power factor to decline, and the too little performance of ventilating of motor that makes of air gap declines, thus affects the heat radiation of motor, and electric machine temperature rise is aggravated.
Tradition PMSM Speed control method many employings weak magnetics detect, namely magnetic flux is weakened with the maximum speed of lifting motor by negative exciting current, the cross, straight shaft current of this method motor in weak magnetic process must be controlled, to avoid the generation of permanent magnet demagnetization situation.
