The BLM series motors are highly cost-effective brushless DC servo motors. Rated speed is 3000 rpm for BLM series motors, and 4000 rpm for 57BL series. Standard model includes a standard 1000 line encoder with differential encoder signals (A, B, Index), and Hall Sensors with standard Hall signals (U, V, W).
When driven by ACS series servo drives, the BLM and 57BL series motors can meet requirements of many applications requiring speed from as low as 1 rpm to as high as 4000 rpm. They can offer AC-servo-like performance, such as high speed, high precision, low motor noise and low heating performance, while at the cost of normal stepping systems. BLM series motors are flange mounted motors, and mounting are compatible with NEMA23 stepping motors. The 57BL series are screw mounted motors
