Parker: BE Series brushless servo motors BE343JJ-KMSN

Parker’s BE Series brushless servo motors produce high continuous stall torque in a cost-saving and performance enhancing package.

The BE Series is designed specifically as a very cost-effective alternative to comparably sized servos. The BE Series also provides exceptional torque with the design’s increased number of magnetic poles. Comparably sized servos have four magnetic poles on the rotor, while BE Series motors have eight. Parker’s BE Series brushless servo motors produce high continuous stall torque in a cost-saving and performance enhancing package.

Unlike traditional servo motors, the BE Series does not have a separate metal housing. Instead, the motor stator laminations are not only used for performance, but provide both structural integrity and the motor shape. This design reduces both material costs and the time required to assemble the motor.

In addition to the manufacturing advantages, the exposed laminations reduce thermal resistance. This allows the heat generated by the motor to escape to the ambient surroundings more efficiently, thus improving time in the peak region and duty cycle.

Parker’s wide range of Bayside® planetary gearheads are perfectly matched to the BE Series motor. Easy selection can be made using Parker’s MotionSizer.
