4.1 4.2 * The 57BL180 is a screw mounted model, above rules inapplicable to this model. Winding connection: △（Delta connection） Hall Sensor: 120° Phase: 3 Shaft Radial Play: 0.025 mm Shaft Axial Play: 0.025 mm@460g Pole Pairs (-): 2 Allowable radial load: Allowable axial load: 75N@20mm from the flange 15N Isolation Level: Class B Isolation Strength: 500VDC for one minute Isolation Resistance: 100M ohms 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.
