    摘要: Circuit arrangements for applying an increasing voltage to a motor with increasing motor speed in a lower speed range and for applying a decreasing voltage to a motor with increasing motor speed in a higher speed range both to obtain proper regulation of the motor while avoiding overheating in startup and overload conditions and to adapt said motor in the startup condition to loads having variable speed-torque requirements.
