Profile: Dynamotors, Inc. specializes in electric motor controls. Our product is variable speed motor. Our variable speed dynamotor with brushless motor control, delivers required power at desired speed. Speed range is determined by the number of field polls built into the motor. One stage of gears, sprockets, chains or drive is easily eliminated. By decreasing the number of field poles in a dynamotor, the speed is increased, and the torque is reduced. Models are available in speed ranges from 200-1200 rpm (8 pole), 400-2400 rpm (4 pole) and 800-4800 rpm (2 pole). Our dynamotor senses rotor speed and position, enabling closed-loop control & maintaining set speed within 2% when load, voltage or temperature changes. By combining the controller within the motor, it eliminates separate controls, wiring and external factors.
