AUSTRALIAN Baldor has released the BSC C series brushless ac servo motors with rare-earth neodymium iron boron magnetics.
There are 25 motors in the range, delivering up to 30Nm continuous stall torque. Ring-shaped magnets are pressed onto the motor shaft to boost magnetic flux levels. This increases torque levels by 20% to 60% compared with Baldor's ferrite-based BSM B-series motors.
The efficiency of the magnets has allowed the length of some motors to be reduced by 2.5cm to 5cm, along with significant weight savings. The increased torque can translate directly into higher throughput.
The new motors offer the same heavy inertias as equivalent BSM B models, as well as the same style of packaging, IEC mounting, and connection arrangements. This allows a simple upgrade path.
The motors provides machine builders with a compact solution for continuous stall torques ranging from 1.2Nm to 30Nm and peak torques from 3.6Nm to 90Nm, with a wide speed capability. A variety of feedback devices are available including resolvers, encoders, and absolute position encoders.
Baldor offers a complementary line of brushless servo drives and mint-compatible motion controller products for servo motion systems with 1 to 12 axes of positioning control. Custom variants are available with user-defined shaft, mounting, or winding parameters.
