Product Details

Nema 11  stepper motor

This 1.8 degree 2 phase stepper motor nema 11 has lower noise, high accuracy, high efficiency and short circuit. This two-phase stepper motor consists of a stator and a rotor. Its stator has 8 poles or 4 poles, a certain number of small teeth are evenly distributed on the pole surface, and the coil on the pole can be energized in two directions. Its rotor is also composed of two pieces of teeth and the like which are uniformly distributed with a small number of small teeth on the circumference. The two pieces are offset from each other by a half pitch. An axially magnetized annular permanent magnet is sandwiched between the two teeth.

Features:

1. 1.8 degree 2 phase stepper motor nema 11 uses bipolar wiring to maintain torque.

2. The stepping motor adopts a fully digitally controlled microstepping drive, and the anti-vibration characteristics in the full speed range are significantly improved.

3. It has a high-performance small-size drive to save space. And it comes with protection that can detect drive anomalies.

4. This kind of motor can control the angular displacement by controlling the number of pulses by the driver to achieve the purpose of accurate positioning. At the same time, the speed and acceleration of the motor rotation can be controlled by the driver to control the pulse frequency, thereby achieving the purpose of speed regulation.
