BSM-Series Background

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 four pole (NEMA 17 and NEMA 23 size motors) and six pole (NEMA 34 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.

Features & Benefits

· Peak torque to 846 oz-in.

· IP65 sealing

· High-flex cables

· Protection from overheating

· Optional encoder

· Optional fail-safe brake

 

Applications

RT-series rotary positioning stages are designed for precise motor driven rotary positioning and indexing. These tables are intended to function independently or in conjunction with other positioning components used in high precision and automation applications. The low-profile design minimizes stacking height in multi-axis configurations and enables RT-series stages to fit where other motorized devices cannot.

RT-series models are available with 67, 98 and 136 mm hub diameters with several resolution options, determined by encoder selected, to match speed and positioning requirements of your application.
