Engineering Overview
As an extended-length model of the 13mm series, FA-1332R features an elongated coreless rotor structure, delivering stronger continuous torque and excellent stability under variable loads. Equipped with 5-segment commutator and premium precious metal brushes, it eliminates cogging torque to realize low-noise and low-vibration operation. This motor supports an ultra-wide voltage range covering low voltage to 24V high voltage, with an extremely short mechanical time constant for ultra-fast start-stop response. Matched G13MF and G13XL gearboxes and encoders are available to meet high-precision closed-loop control demands for long-term running equipment.
Typical Applications:
• 24V industrial miniature precision actuators
• High-torque long-running handheld medical devices
• Wide-voltage adaptive micro fluid transfer pumps
• Professional high-load cosmetic drive equipment
