Product Description The FF-337SA is a specialized DC motor engineered for personal care electronics and high-precision cutting tools. Known for its compact "flat" profile, this motor delivers the high torque and steady RPM required for oscillating blades in electric shavers and hair clippers. The internal carbon brushes ensure a stable electrical connection and consistent performance over a wide range of battery voltages, making it a reliable replacement part or a core component for custom grooming gadgets.

Key Features

  • Compact flat-sided design to fit easily into ergonomic handheld grips.

  • Optimized for low-voltage operation (single or dual cell Ni-MH/Li-ion).

  • High-speed performance designed for smooth, snag-free cutting.

  • Low noise and low vibration characteristics for comfortable tool usage.

  • Durable metal housing with carbon brushes for extended motor life.

Technical Details

  • Operating Range: 1.2V – 3.7V DC

  • Nominal Voltage: 2.4V DC

  • Speed at 2.4V: ~8800 RPM

  • Efficiency: High-efficiency commutator design

  • Shaft Length: ~8mm to 10mm (varies by batch)

  • Housing Dimensions: ~28mm x 20mm x 15mm

  • Mounting Holes: M2 threaded holes on the front face

  • Rotation: Bi-directional (Clockwise or Counter-Clockwise based on polarity)

Prototyping and Engineering Tips from Robogears

  • Voltage Management: While the motor can run at 3.7V (fully charged Li-ion), keep in mind that higher voltages increase speed and heat. If using a 3.7V battery, we recommend a simple PWM speed controller to keep the motor within its optimal temperature range for longevity.

  • Mechanical Coupling: The 2.0mm shaft is compatible with standard clipper cams and eccentric weights. Ensure the load is balanced; an off-center load in hair clippers can cause excessive noise and wear down the bushings.

  • Interference Suppression: Like most brushed motors, the FF-337SA can generate EMI (Electromagnetic Interference). Solder a 0.1uF ceramic capacitor across the motor terminals to prevent electrical noise from affecting nearby microcontrollers or wireless modules.

  • Replacement Check: If using this as a replacement for a broken shaver motor, verify the physical dimensions and shaft length, as many personal care tools use very specific tolerances.

Package Includes

  • 1 x FF-337SA High-Speed DC Motor
