25-73W BM05 Series Brushless Servo Motors BM05/1 BM05/2 BM05/3 25-73W 25-73W BM05 Series Brushless Servo Motors

The BM05 series brushless servo motors provide a choice of size and performance with output power ratings up to 130 watts. The brushless construction combined with high grade ball bearings provide a very long life in applications requiring a variable speed drive at high continuous torque. The units utilise a 3 phase design with hall effect commutation combined with an internal rotor incorporating high energy magnets to provide optimum power transmission. The provision of a rear shaft enables a choice of encoders to be readily fitted to provide a position reference as well as commutation signals for a use with more sophisticated servo drive system if required.

Equipped with a NEMA 23 size mounting flange and shaft design, the BM05 Brushless motors are physically interchangeable with hybrid stepper motors. Using the standard B5 brushless drive the motors provide a bi-directional variable speed capability up to 3000 rpm with peak torque ratings in excess of 0.9Nm for rapid acceleration. In this form they are ideally suited for small conveyor drives, pump drives, printing and paper handling applications as well as general purpose industrial drives requiring variable speed and long life.
