Brushless Servo Motors, Metric Frame

Brushless Servo Motors that have windings in the stator and permanent magnets attached to the rotor. No brushes are used. Motor rotation is achieved by means of electrical commutation performed by the drive. Brushless servo motors provide high acceleration, high torque, and no maintenance. Brushless Servo Motors offer the highest torque-to-weight ratio and are commonly used in the highest throughput, precision and demanding applications. Brushless motors are available in both metric and imperial frame sizes, and in both slotted and slotless designs .

Electromate®'s family of Metric Brushless Servo Motors includes:
