1 BM Series Rotary Motors BM Series DC Brushless Rotary Servomotors Standard NEMA frame sizes Neodymium iron boron rare-earth magnets maximize performance Skewed stator with 8-pole design minimizes torque ripple and cogging for smooth velocity control over a greater speed range Optional IP65-level construction allows use in harsh environments, including washdown Choice of encoder/hall output or resolver feedback Optional brake, front shaft seal, and precision gear reducers High-Performance Design The BM series motors are Aerotech s high-performance DC brushless rotary motors. The motors feature neodymium iron boron magnets for maximum torque and acceleration in a small package. A skewed stator design and an eightpole rotor provide less torque ripple and smoother velocity. The BM series motors can reach speeds up to 1, and accelerations to 7, rad/sec 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. Application Flexibility The standard motor has a 1-line encoder (4-line count after quadrature), RS-4 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. 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. output torque ranges from.53 (75 ) to 3 (8 ), with peak torques to 94.4 (84 ). Standard frame sizes include NEMA 3, 34, 4, and IEC 14. 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. All Aerotech motors are manufactured following ISO91 standards.
