LS57E20-D2B42S02 Closed-loop brake stepper motors

LEESN 57mm brake stepper motor adopts electromagnetic brake, brake stepper motor to achieve high-speed zero loss silent operation; The brake is tightly integrated with the motor. Built-in 1000-wire encoder, rear 2N permanent magnet brake. With low heating, large torque, high stability. ADAPTS to drive DE57.
① Spindle mode:
Provide single flat, double flat, keyway, hobbing and other shaft delivery modes;
② Lead mode:
According to different application requirements, provide customized winding and routing methods;
③ Accessories selection:
A variety of accessories for stepper motors are available, such as encoders, planetary reducers, power off brakes.

Stepper motor is not a constant torque motor, the higher the running speed the output torque will be smaller, so pay attention to the motor to maintain torque parameters at the same time should pay attention to the actual, working speed of the motor output torque (refer to the dynamic torque curve); And we recommend reserving a margin of 1.5 times, so as to avoid the phenomenon of stepping motor loss in the case of overload.
