Product Name: Rotary Motors BM

Product Description

• Standard NEMA frame sizes 

• Neodymium iron boron rare-earth magnets maximize performance

• Optional IP65-level construction allows use in harsh environments, including washdown

• Choice of encoder/HED or resolver feedback 

• Optional brake, front shaft seal, and gear reducers

High-Performance Design
The BM series consists of Aerotech’s high-performance DC brushless rotary servomotors. The motors feature neodymium iron boron magnets for maximum torque and acceleration in a small package. The BM series motors can reach speeds up to 10,000 rpm and accelerations to 270,000 rad/sec2 for improved machine cycle times. Unlike DC brush-type servomotors, the BM series are brushless and maintenance free. This makes them ideal for critical applications where downtime cannot be tolerated. 

In addition, the BM series motors have very high power density resulting in high torque in a compact package. Optional IP65 sealing make these motors ideal for harsh environments such as machine tool and even in washdown applications such as food processing.

Wide Torque Range
The BM motor series covers a wide range of torque and package sizes. Continuous output torque ranges from 0.55 N-m (78.3 oz-in) to 31.6 N-m (280 lb-in), with peak torques to 94.9 N-m (840 lb-in). Standard frame sizes include NEMA 23, 34, 42, and IEC 142. This makes it easy to mount any motor to Aerotech’s gearbox line with no adapter plates. These motors are well-suited to general purpose and high-end servo applications. 
Application Flexibility
The standard motor has a 1000-line encoder (4000-line count after quadrature), RS-422 line driver output with Hall effect device outputs for commutation, and MS connectors. Options include increased encoder resolution, encoders with amplified sine-wave output, resolver feedback, sealing for IP65 level protection, brakes, and gearboxes. Standard models can be delivered from stock and custom variations can be engineered to your requirements with minimal lead time.
