BPS suitable series of frequency sensitive rheostat with a flywheel (moment of inertia) of each stream winding type motor,Composition of the regulator with slip.

A varistor is a non-contact electromagnetic component that is equivalent to an equivalent impedance.During the motor starting process,Automatic drop due to the reduction of the equivalent impedance rotor current frequency (automatic variable resistance)Therefore, the electric vehicle can be smoothly started up only by the first-order varistor.
