BL-140 Series Brushless DC Motors

BL-140 Series Brushless DC Motors

The BL-140 series (130 &142 mm diameters) are electromechanically optimized for high output power, high torque density, and low cogging torque.

Their high power density ratio allows a smaller size motor to be used in many applications, saving space and weight. The compact BL motors are well-suited for applications demanding low audible noise and long life.

BL motors are also available as frameless versions for direct machine integration.

Our engineering department is available for consultation to help you tailor a brushless motor for your specific application.
