12V DC Coreless Gear Motor 1725 With Gearbox
Product Overview
The 17mm coreless DC gear motor, model NFP-CGM1740, operates at 12V DC. Therefore, it is suitable for compact drive systems that need high speed, smooth operation, and stable torque output.
In addition, the single motor reaches a no-load speed of 13,384rpm. As a result, the motor can provide fast response before gearbox reduction.
Moreover, the 4:1 gearbox reduces speed and increases usable output torque. Therefore, this gear motor works well in robotics, medical equipment, and industrial automation systems.
Main Features
- 17mm coreless motor: The compact motor body helps save space. Therefore, it fits small product structures.
- 12V DC operation: The motor works with a 12V DC power supply. As a result, it can match many common control systems.
- 4:1 gearbox ratio: The gearbox reduces speed and improves torque output. Therefore, it is useful for controlled motion.
- High efficiency: The single motor reaches up to 84.9% efficiency. In addition, this helps reduce energy loss under proper load.
- D-cut output shaft: The shaft design helps reduce slipping. Moreover, it supports easier mechanical assembly.

Jacklyn Boatright –
The coreless design ensures efficient performance and smooth operation with minimal wear and tear. It runs quietly and I have found it to be very reliable so far.👏
Paul Kelvin –
These coreless gear motors did’t heat up quickly. It was an exact fit 10 minutes to install them no problems at all, because the reserved space is really suitable. We would buy again if needed.
Amason –
