The stepper motors move in precisely repeatable steps, hence they are the motors of choice for the machines requiring precise position control. The NEMA17 4.2 kg-cm Stepper Motor can provide 4.2 kg-cm of torque at 1.2A current per phase. The motor’s position can be commanded to move or hold at one position with the help of Stepper Motor Drivers. The NEMA17 4.2 kg-cm Stepper Motor provides excellent response to starting, stopping and reversing pulses from stepper motor driver. It is a brushless DC motor, so the life of this motor is dependent upon the life of the bearings. The position control is achieved by a simple Open Loop control mechanism so doesn’t require complex electronic control circuitry. It comes with a detachable 70cm cable which makes wiring and rewiring very fast and easy work. The design of this cable is such that it can directly be mounted on a stepper motor controller. So, playing with the connection is done with just snap of fingers. The motor’s shaft has been machined for good grip with a pulley, drive gear etc., and especially avoiding stall or slip.
