Nema-17 Stepper Motor 4Kg (Type 17PM-K052EP01CN)

NEMA 17 Stepper Motor 4 kg-cm (Type 17PM-K052EP01CN)

The NEMA 17 Stepper Motor is the industry standard actuator for applications requiring highly precise and repeatable positioning control. This specific model (Type 17PM-K052EP01CN) provides an excellent balance of size, speed, and torque, housed in the widely recognized 1.7-inch x 1.7-inch NEMA 17 frame size.

As a Bipolar stepper motor, it operates by sequentially energizing two internal coils (phases), moving the rotor in discrete, predictable steps. With a standard 1.8° step angle, it requires 200 full steps to complete one full 360° rotation. Its strong 4 kg-cm (0.4 N-m) holding torque ensures the motor shaft remains locked in position when unpowered or during static phases, a critical feature for vertical axes on 3D printers and stability in CNC machines. The motor requires an external stepper motor driver (such as an A4988 or DRV8825) to manage the current and sequencing needed for operation.
