- Dual 12 V and 7.4 V ratings suit a range of DIY projects
Yahboom 520 Motor 333RPM
The Yahboom 520 is a 12V DC geared motor rated at 333 RPM, designed for hobbyists building DIY robots, smart vehicles or science experiments. Its Hall-effect encoder provides AB-phase pulses for precise speed and direction feedback. Makers who need closed-loop control for Mecanum-wheel platforms or balancing robots will find the encoder output essential.
Dual-voltage torque headroom
Operating at either 12V or 7.4V, the motor delivers high torque through a full metal gearbox that resists heat and wear under sustained loads. The pure copper rotor and carbon brushes keep resistance low for strong current handling. Builds requiring continuous stall torque beyond the gearbox rating or speeds far above 333 RPM will exceed the mechanical limits.
Encoder and shaft integration
The bundled Hall encoder disc and D-shaped hardened steel output shaft simplify mounting couplers and reading velocity data without extra sensors. Carbon brushes extend service life compared to copper brushes. Projects that lack a microcontroller capable of decoding quadrature pulses or that require a round output shaft will need additional adaptation.

Questions about this item
Can I use the 520 motor with a 12 V or 7.4 V supply I already have?
The motor is rated for both 12 V and 7.4 V operation, so either supply voltage will work.
How do I confirm the Hall encoder is sending correct AB pulses after wiring?
Connect the encoder leads to a microcontroller, spin the shaft and watch for two square-wave channels that change state as the motor turns.
Does the package include mounting hardware or couplers for the D-shaped output shaft?
Only the geared motor with its D-shaped steel shaft is supplied; couplers, brackets and screws must be sourced separately.
