BSM-series of brushless servo motors offer powerful eight pole (40 x 40mm, 60 x 60mm and 80 x 80mm) motors. These servo motors are custom engineered for high speed, high torque applications that involve dynamic load changes while in a smaller envelope and at a lower cost.
NUTEC BSM series of brush-less servo motors have been custom engineered to offer higher performance in a smaller envelope and at a lower cost than standard off-the-shelf brushless servo motors. Powerful eight pole (40, 60 and 80mm SQ size motors) with rare earth magnets and skewed windings to reduce cogging, and class 3 ABEC bearings provide high speed, high torque, long life, and very smooth low speed operation, features required in complex servo systems.
Brushless servo motors are a class of servo motors that operate by using electronic commutation rather than electromechanical commutation as used in brush-type motors. Brushless motors have a permanent magnet rotor and the wound stator is on the outside allowing for greater heat dissipation. As electronic commutation is a function of rotor position there are no brushes to wear out, limit speed, cause electrical noise, or create contamination.
