12Nm Stepper Motor

The 12Nm stepper motor is an electric motor product capable of converting control signals into rotational motion at fixed step angles. The motor is typically designed to the size 86 (NEMA 34) standard, easily integrating into existing industrial mechanical systems.

Thanks to its permanent magnet structure combined with high-precision magnetic teeth, the stepper motor generates high torque right from low speeds, ensuring firm shaft-holding capability when stopped.

Overall design of the 12Nm stepper motor

The 12Nm stepper motor features a robust square block body made of thick cast aluminum alloy, with surface treatment for corrosion resistance and optimized heat dissipation. This structure helps the motor operate stably in continuous working and heavy-load environments.

The motor shaft has a large diameter, is hardened and machined with a keyway or flat surface, making it suitable for coupling with gearboxes, pulleys, gears, or large ball screws. The wiring is wrapped in high-quality insulation, ensuring a safe connection with high-power stepper motor drivers.

Detailed structure of the 12Nm stepper motor

The 12Nm stepper motor is composed of the following main components, ensuring long-term performance and durability:

• Stator (stationary part): The stator uses laminated electrical steel sheets to reduce eddy current losses. The windings are made of heat-resistant pure copper wire, helping to create a strong and stable magnetic field when control pulses are supplied.
• Rotor (rotating part): The rotor is a combination of a permanent magnet and a precision-machined magnetic tooth system, allowing the motor to achieve high torque and definitive step motion, reducing vibration and increasing positioning accuracy.
• Shaft and bearings: The hardened steel shaft combined with high-quality deep groove ball bearings at both ends helps the motor withstand heavy loads and run smoothly for a long time.
• Mounting flange: The flange is machined to the correct size 86 standard, ensuring high concentricity and convenience during installation or replacement in the system.
