NEMA 17 Stepper Motor 42x40mm 1.5A 0.40Nm A0022-B

The NEMA 17 Stepper Motor (Model A0022-B) is a high-torque, high-precision hybrid bipolar stepper motor designed for demanding motion control applications. With a standard 42x40mm frame size, it delivers a robust holding torque of 0.40 N.m at a rated current of 1.5A per phase. It features a 5mm D-shaped shaft to ensure secure, slip-free coupling, making it the ideal choice for 3D printers, CNC engravers, and precision robotics.

This motor is highly reliable, offering low phase resistance of 2.0 ohms and 5.6 mH inductance to minimize heat generation and maximize efficiency. It is fully compatible with popular stepper drivers such as the A4988, DRV8825, TMC2208, and TMC2209, and can be easily integrated with Arduino, ESP32, Raspberry Pi, or dedicated CNC controllers for seamless automation projects.

Features:

• High Torque Output: Delivers a minimum holding torque of 0.40 N.m (4.0 kg-cm) for reliable motion control.
• Standard NEMA 17 Form Factor: 42.3mm x 42.3mm faceplate with a compact 40mm body length.
• D-Shaped Shaft: 5mm diameter shaft with a flat edge prevents pulley or coupler slippage under high loads.
• Precise Step Angle: 1.8-degree step angle (200 steps per revolution) ensures high positioning accuracy.
• Standard PH-6P Connector: Features an onboard 6-pin JST-PH terminal for easy, plug-and-play wiring.
• Optimized Electrical Specs: Low phase resistance of 2.0 ohms and 5.6 mH inductance for efficient power delivery and reduced heat generation.
