8Nm Stepper Motor

The 8Nm stepper motor is an electric motor product capable of converting control signals into rotational movement according to fixed step angles. The motor is typically designed to standard size 86 (NEMA 34), ensuring flexible installation and high compatibility with current industrial mechanical systems. The 8Nm stepper motor features a permanent magnet design combined with precise magnetic teeth, generating high torque right from startup, keeping the shaft stable, and minimizing step loss during operation.

General design of the 8Nm stepper motor

The 8Nm stepper motor features a sturdy square-block housing made from thick cast aluminum alloy, with surface treatment for corrosion resistance and enhanced heat dissipation. This structure allows the motor to operate continuously in high-intensity industrial environments.

The motor shaft has a large diameter, made from hardened steel, machined with a keyway or flat surface to ensure efficient torque transmission when coupled with pulleys, gears, or lead screws.

Detailed structure of the 8Nm stepper motor

The 8Nm stepper motor is composed of the following main components to ensure performance and lifespan:

• Stator (stationary part): The stator uses layered electrical engineering steel laminations to reduce eddy current losses. The windings are made of high-temperature-resistant pure copper wire, creating a strong and stable magnetic field when control pulses are applied.
• Rotor (rotating part): The rotor uses permanent magnets combined with precisely machined magnetic tooth structures, helping the motor achieve high torque, smooth movement, and good repeatability.
• Shaft and bearings: The hardened steel shaft combined with high-quality deep groove ball bearings helps the motor withstand heavy loads, reduce friction, and maintain smoothness during operation.
• Mounting flange: The flange is machined to standard size 86, ensuring high concentricity and convenience for installation and replacement within the system.
