NEMA 17 Stepper Servo Motor
Electrical Specification
The closed-loop NMEA 17 stepper motor is a stepper motor, adding a position feedback device(photoelectric encoder or magnetic encoder), which uses the control method similar to the servo motor to a form a closed-loop stepper system.
The closed-loop NEMA 17 stepper motor and open-loop NEMA 17 stepper motor have the same frame size, guide diameter, bolt hole circle, and bolt hole diameter, so the mounting bracket remains unchanged. The greater torque available in the closed-loop stepper system means that the axis diameter of the closed-loop stepper motor may be larger, but this can be easily solved by changing the coupling.
The performance of a closed-loop control system is superior to the open-loop control system. If you have an interest in NEMA 17 stepper servo motor, you can contact us. We can customize according to your needs.

Ability
Ability:
The NEMA 17 closed-loop stepper Motor(servo motor) is the smallest size that I.CH manufactures. Combining the advantages of the servo motor and stepper motor, this motor not runs smoothly, but also less resistance. If you have needs, the encoder can provide.
Advantage:
1, Different types of solutions to control the budget.
2, 1.8 step angle.
3, Many options can choose.
4, High precision.
Services:
1, Selection service.
2, Installation instruction service.
3, Repair and displacement service.
FAQ:
1, what is the performance of hysteresis for the closed-loop stepper motor?
You can see the performance from PDF.
2, Which is the type of output shaft that I.CH can provide?
We can provide different types such as parallel shafts.
