Coreless rotor structure
The ironless rotor supports low inertia, fast acceleration and efficient electromechanical response in compact equipment.
High torsional rigidity and constant torsional backlash over the entire gearbox service life ensure consistently high performance
High torque density thanks to high performance and short design
Highest quality standards for a long service life and extended maintenance intervals
The SP10ZYCC25P 10 mm brushed coreless DC motor uses an ironless rotor to reduce moving mass and rotational inertia. Its compact size, low weight, smooth operation and responsive control suit precision mechanisms where space and dynamic performance matter.
The ironless rotor supports low inertia, fast acceleration and efficient electromechanical response in compact equipment.
The 10 mm motor body fits medical devices, compact robots and high-end instruments with limited installation space.
Select the direct motor configuration or an 18:1 gearmotor with a 256-pulse magnetic encoder for lower output speed and closed-loop feedback.
The 12 VDC platform is available as the 10ZYCC25P-EK256-1 motor configuration or as the 10ZYCC25P-G18-EK256-1 gearmotor with magnetic encoder.

The coreless rotor supports responsive starts, stops and direction changes with smooth low-noise operation. The geared configuration and magnetic encoder extend the platform to lower-speed positioning and feedback-controlled motion.

Compact pumps, dosing mechanisms and portable instruments requiring smooth miniature motion.
Small joints, grippers and auxiliary axes where low inertia improves command response.
Optical, analytical and measurement equipment with limited installation space.
Feedback-controlled mechanisms that benefit from the geared encoder configuration.
Select the direct motor for high-speed miniature motion or the geared encoder version for reduced speed, higher output torque and feedback capability.
Share the required speed, torque, duty cycle, gearbox, encoder and installation constraints for configuration support.
