Stepper Motor Nema 17 JK42HS48-1684-08AF

Description :

A step motor is a brushless DC electric motor that divides a full rotation into a number of equal steps. The motor's position can then be commanded to move and hold at one of these steps without any feedback sensor (an open-loop controller), as long as the motor is carefully sized to the application.

This is a 2 phase step motor.There are two basic winding arrangements for the electromagnetic coils in the two phase stepper motor: bipolar and unipolar.It is high quality.Its motor length is 34mm.
