 Features:
 High holding torque at high speed.A stepper motor is an electric motor that is able to create sharp movements.It is widely used in 3D printer, monitor / Medical/Textile/ Packaging Machinery, Stage Lighting,ect.






Operating Principle

Our stepper motor is made up of rotor,stator, bearing and housing. A certain electric current goes through the stator winding timely, then produces a rotating magnetic field within the motor. Under the action of magnetic suction, the rotor will follow this and creates a rotating magnetic field. The stator and rotor flux in each chain, and then produce rotary torque output.
 

Warning

Make sure the motor connect to a constant current or chopper drive controller before you test motor.
Connecting the motor directly to a power supply will destroy the motor.
