Brushless DC Motor Serves Up High Speed And Torque

Suitable for machine tool spindles and other high power applications, the company's latest brushless DC motor delivers speeds up to 21,000 rpm and produces up 14.2 in-lb of torque at full speed. Slower speeds will yield up to 15 in-lb of torque. Via a dual plane rotor-balancing scheme, the motor is said to be extremely quiet. It features oversize front and rear bearings and a secondary, internally-independent Hall device tachometer arrangement. Measuring 4.875" in diameter by 7" long, the motor has a standard operating voltage of 370V and a variety of electrical winding options available for other voltages.
