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 the stepper motor driver.

They are very useful in various applications, especially those that demand low speed with high precision. Many machines such as 3D Printers, CNC routers and Mills, Camera Platforms, XYZ Plotters, etc.

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 to 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 a snap of the fingers. The motor’s shaft has been machined for good grip with a pulley, drive gear, etc., and especially avoiding stall or slip.

Note :

  1. The Nema17 4.2kgcm Stepper motor dimensions and weight may have  ±2% error.
  2. Resonances can occur because of improper installment.
  3.  Not easy to operate at extremely high speeds.
  4.  You need a TB6600 or DM542 driver to run NEMA motors because they have switches to provide more current to motors.

Features :

  1. The input pulse decides the rotation angle of the motor.
  2. High accuracy of around 3 to 5% a step.
  3. Provides good starting, stopping, and reversing.
  4. Control of this motor is less costly because of the exclusion of complex control circuitry.
  5. The speed is proportional to the frequency of the input pulses.
