Deer Park, NY, - The NUTEC Components, Inc. BSM series of brushless 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.

Designed for encoder controlled commutation NUTEC BSM series brushless motors can easily be configured with dual feedback loops providing the greatest possible control over speed and position.

Additional features include: IP65 sealing against enviromental conditions, high-flex cables, and an optional fail-safe brake to protect the system in case of a power failure.

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, limiting speed, causing electrical noise, and create contamination.

For highest positioning performance in precision applications NUTEC utilizes sinusoidal commutation and recommends the MICROMATIC-5 integrated brushless servo control system.

Distinct advantages of brushless servomotors over brush-type servomotors are:

1. Higher speeds
2. Longer life
3. Cleaner operation
4. Less heating
5. Higher duty cycles
