LEESN new generation 42mm*42mm(NEMA17) two-phase 1.8° closed-loop stepper motor, built-in 1000-wire encoder, with miniaturized design, low heating, high stability, high consistency, greater torque, higher performance, recommended for the driver DE42.
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:
Provide a variety of accessories for the stepper motor, such as planetary reducer, power off brake, etc.

Closed-loop stepper motor is a kind of stepper motor system, which is different from the traditional open-loop stepper motor system. It has a feedback control mechanism, which can monitor and correct the position error of the motor in real time to improve the performance and accuracy.
