Description

1.8° Step Angle Nema17 Motor – 42mm, High Torque Geared for Robotics Joints

The 1.8° Step Angle Nema17 motor, measuring 42mm, is a high-torque geared solution engineered for robotics joints. Its 2-phase planetary gearbox amplifies torque output, ensuring precise, smooth movement critical for robotic articulation—from small-scale humanoid fingers to industrial arm joints. With a 1.8° step angle, it delivers exceptional positional accuracy, while the compact 42mm frame fits seamlessly into space-constrained robotic designs. Ideal for both hobbyist and professional robotics, it balances power and precision, making it a reliable choice for applications demanding consistent, controlled motion in joint actuation.
The necessary driving device or control device for the customer can cooperate with the customer for development.
The basic step angle of the motor is 1.8 degrees.
At the same time, we can provide the same size products with a step angle of 0.9 degrees!
