This Nema17 4.2 kgCm stepper motor (With detachable connector & 70 cm Cable) can be used on any standard small CNC machines.

This motor’s position can be the command to move and hold at one of these steps, as long as the motor is carefully sized to the application with respect to torque and speed.

We are engaged in supplying and wholesaling a quality approve the collection of Stepper Motors which is highly acknowledged and accept for long service life and high reliability.

Advantages :

  1. The rotation angle of the motor is proportional to the input pulse.
  2. The motor has full torque at standstill(if the windings are energized)
  3. Precise position and repeatability of movement since good stepper motors have an accuracy of 3 – 5% of a step and this error is noncumulative from one step to the next.
  4. Excellent response to starting/stopping/reversing.
  5. Very reliable since there are no contact brushes in the motor. Therefore the life of the motor is simply dependent on the life of the bearing.
  6. The motors response to digital input pulses provides open-loop control, making the motor simpler and less costly to control.
  7. It is possible to achieve very low-speed synchronous rotation with a load that is directly coupled to the shaft.
  8.  A wide range of rotational speed can be realized as the speed is proportional to the frequency of the input pulses.

Disadvantages :

  1. Resonances can occur if not properly controlled.
  2.  Not easy to operate at extremely high speeds.

Note: The Nema17 4.2 kg cm Stepper motor dimensions and weight may have  ±2% error.
