Leadshine's BLM series motors are highly cost-effective brushless DC servo

motors. Rated speed of BLM series motors is 3000 rpm (That of the 57BL180

is 4000 rpm). Standard model includes a 1000-line differential encoder

(EA+/EA-, EB+/EB-), and Hall Sensors with standard Hall signals (U, V, W).

When driven by Leadshine ACS series servo drives, the BLM series motors

can meet requirements of many applications requiring speed from as low as 1

rpm to as high as 4000 rpm. They are able to 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 is compatible with that of NEMA23

stepper motors. The 57BL180 is a screw mounted motor.
