JK42HS40-1204AF-02 NEMA17 4.2 kg-cm Stepper Motor – D-Type Shaft

The NEMA17 4.2 kg-cm Stepper Motor seems like an ideal choice for applications requiring precise position control, thanks to its ability to move in precisely repeatable steps. With a torque output of 4.2 kg-cm at 1.2A current per phase, it offers a balance of power and efficiency for various tasks.

The motor’s compatibility with stepper motor drivers enables precise control over its position, allowing it to move or hold at specific positions as commanded. Its responsiveness to starting, stopping, and reversing pulses from the driver ensures smooth and accurate operation, essential for applications where precise motion control is critical.

The versatility and precision offered by stepper motors make them indispensable in various applications, especially those requiring low speed and high precision. From 3D printers to CNC routers and mills, camera platforms, and XYZ plotters, stepper motors find widespread use in a range of machinery where precise control over position is paramount.

The brushless DC motor design of the NEMA17 4.2 kg-cm Stepper Motor ensures reliability, with its lifespan largely dependent on the durability of its bearings. The simplicity of its open-loop control mechanism simplifies electronic control circuitry requirements, making it easier to implement in various systems.

The inclusion of a detachable 70cm cable streamlines wiring and rewiring processes, enhancing ease of use and maintenance. The design allows for quick mounting onto stepper motor controllers, facilitating seamless connections with minimal effort.

Furthermore, the carefully machined shaft of the motor ensures a secure grip with pulleys, drive gears, and other components, minimizing the risk of stall or slip during operation.

Note:

• There may be a ±2% error in the dimensions and weight of the Nema17 4.2kgcm Stepper motor.
• When something is installed incorrectly, resonances can happen.
• Operating at such fast speeds is difficult.
• To run NEMA motors, you need a TB6600 or DM542 driver since they contain switches that allow the motors to receive higher current.
• Similar to this motor, we also have 42HS40-1504 NEMA17. The differences are that 42HS40-1504 NEMA17 has a 1 metre cable, a 21 mm shaft length, a 38 mm motor height, and some technical specifications like a 1.5 A/phase supply current. Please take note and adjust purchases.

Features:

• The motor’s rotation angle is determined by the input pulse.
• High precision, ranging from 3 to 5% per step.
• Offers effective reversing, stopping, and starting.
• This motor’s control is less expensive because complicated control circuitry is not used.
• The frequency of the input pulses determines how fast something moves.
