NEMA17 Stepper Motor - 4.2 kgcm, with Detachable 70cm Cable

The NEMA17 4.2 kgcm Stepper Motor is a reliable and precise motor designed for applications requiring accurate position control. With its ability to provide 4.2 kgcm of torque at 1.2A current per phase, this motor is ideal for machines such as 3D printers, CNC routers and mills, camera platforms, and XYZ plotters.

  Key Features:  

• Precise Position Control: Stepper motors move in precisely repeatable steps, making them perfect for applications that demand precise position control.
• High Torque: With a holding torque of 4.2 kgcm, this motor can handle tasks requiring substantial torque.
• Excellent Response: The motor responds well to starting, stopping, and reversing pulses from stepper motor drivers, ensuring smooth operation.
• Brushless DC Motor: As a brushless DC motor, its lifespan is dependent upon the life of the bearings, providing reliable performance over time.
• Detachable Cable: Comes with a detachable 70cm cable for easy wiring and rewiring. The cable is designed for quick mounting on a stepper motor controller.
• Shaft Design: The motor's shaft is machined for good grip with pulleys, drive gears, etc., minimizing the risk of stall or slip.
