Engineering Overview
FA-2607R is a distinctive ultra-short body model in the 26mm series, adopting a special design with 2 pole pairs and 6 commutator segments, which is different from conventional motors. Equipped with wear-resistant ball bearings, it delivers excellent rotational precision and long service life. Thanks to the ultra-small rotor inertia and industry-leading low mechanical time constant across all versions, the motor achieves instant start and stop with extremely sensitive response. It provides four voltage options, including two independent 12V versions with totally different speed and torque characteristics for flexible selection. The 12V/08A version features prominent stall torque for heavy-load instantaneous startup. The coreless rotor structure effectively eliminates cogging torque, ensuring smooth and low-noise operation. Its ultra-compact size and lightweight design make it ideal for highly integrated miniature precision equipment.
Typical Applications:
• Miniature high-speed precision testing instruments
• Compact wearable intelligent drive components
• Micro servo control units for small robots
• Portable precision medical and beauty tools
