Brushless Motors AC Speed Control Motors
... Brushless motors compare the setting speed with the speed feedback signals from the motor at all times and adjust the motor's applied voltage. For this reason, even if the load changes, stable rotation is performed from low speed to high speed. With inverter-controlled (V/F control) three-phase indu ...
