Engineering Overview
As an upgraded model of the 26mm series, FA-2610R adopts 2 pole pairs and 6 commutator segments, which optimizes commutation performance and operational stability. Equipped with high-precision ball bearings, it features high structural rigidity and extended service life for long-term continuous operation. The motor retains the advantages of coreless design, completely eliminating cogging torque to achieve smooth and low-noise rotation. All specifications have ultra-short mechanical time constant and ultra-low rotor inertia, enabling ultra-fast start, stop and dynamic response, ideal for scenarios requiring frequent speed changes. It is equipped with four voltage grades covering 3V to 12V, and two independent 12V versions with different speed-torque characteristics to meet diverse load demands. Compact structure and moderate weight make it widely applicable to highly integrated miniature precision equipment.
Typical Applications:
• Mini servo control systems
• Portable precision testing instruments
• Compact wearable drive components
• Small intelligent robot actuators
