NEMA 17 JK42HS40-1704 4.2 kg-cm stepper motor 4 wire Round Shaft bipolar for CNC / 3d printer / Robotics

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 Motors Drivers . The NEMA17 4.2 kg-cm Stepper Motor provides excellent response to starting, stopping and reversing pulses from Stepper Motors Drivers. 

They are very useful in the various application, especially which demands low speed with high precision. Many machines such as 3d Printers , CNC Router and Mills, Camera Platforms, XYZ Plotters etc.

It is a brushless DC Motors , so the life of this motor is dependent upon 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 motors 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.

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

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 TB6600 or DM542 driver to run NEMA motors because they have switches to provide more current to motors.
