摘要
During compound voltage driving for series motor, a speed change affect can be obtained from the change in torsion in combination with the load. However, during low voltage driving or light loading, the speed reduction and excitation decrease, compared to output of same torsion will result in poor rate of speed adjustment and low efficiency. The present design relates to a compensation principle and circuit device for compound voltage driving series motor, and more specifically there is an independent power supply, when motor is at low voltage driving or light-loaded operation, the assisted exciting power supply will directly employ series winding as the load for exciting in order to promote the efficiency of electrical load during low voltage and low speed driving.
