4.2 kg-cm Stepper Motor

Stepper motors move in precisely repeatable steps, hence they are the motors of choice for machines requiring precise position control. The 4.2 kg/cm stepper motor can provide 4.2 kg/cm of torque at 1.2 A current per phase. With the help of stepper motor drivers, the motor’s position can be commanded to move or held in a fixed position. The 4.2 kg/cm stepper motor provides excellent response to starting, stopping, and reversing pulses from the stepper motor driver.
