NEMA 8 Stepper Motors (20mm)
High torque, custom-built available
- Frame size: 20mm (NEMA 8)
- Holding torque up to 29.4mNm
- Step angle: 1.8º
Motion Control Products' NEMA 8 hybrid stepper motors, setting new standards for torque output compared to conventional hybrid stepper motors. These motors harness the immense power of rare earth magnets, a departure from the conventional permanent magnets.
Our standard high-torque NEMA 8 stepper motors are designed as 2-phase motors, featuring a 1.8-degree step angle and offering a single or double output shaft option, ensuring an impressive holding torque of up to 29.4mNm in the miniature frame size of 20mm. To enhance functionality and control, we offer the option of integrating optical encoders and planetary gearboxes with these motors, ensuring seamless and precise motion control.
The matched stepper drives of the EM-S series are designed to work seamlessly with these motors, offering exceptional control. These drives are capable of handling motors with an output current of up to 7A, ensuring that you have the power and precision needed for your applications
For those seeking a tailored solution, we offer a range of NEMA 8 stepper motors with various options, including customised windings, multiple mounting flange choices, diverse output shaft configurations, and an extended torque range. These tailored options can be made available upon request, although minimum quantity requirements may apply to non-stocked items.
