Small silver DC motor with metal gearbox and D-shaped shaft

yahboom

yahboom 520 DC motor 12 V 7.4 V 550 RPM

SKU CH-BGKW-V0E51

A 520-size geared DC motor running at 550 RPM with Hall encoder feedback for speed and direction control

  • Full metal gear resists heat and wear for durable operation
  • Carbon brush and copper rotor deliver high torque and long life
  • D-shaped steel shaft provides secure coupling and impact resistance
  • Hall encoder supplies AB phase pulses for precise speed and direction control
  • Runs at 12 V or 7.4 V with 550 RPM output

DIY Motor for Toys and Experiments

The Yahboom 520 DC motor is built for hobbyists assembling small robots, science projects or custom toys. It runs on either 12 V or 7.4 V supplies, making it flexible for battery-powered or bench-top use. The 550 RPM output suits low-speed, high-torque tasks such as wheeled platforms or gear-driven mechanisms.

Hall Encoder for Closed-Loop Control

A built-in Hall-effect incremental encoder with a magnetic disc provides AB phase pulses so a microcontroller can measure speed and direction accurately. This feedback lets builders implement PID loops for precise navigation in Mecanum-wheel cars, balance bots or autonomous vehicles. Without the encoder the motor runs open-loop only.

Metal Gearbox and D-Shaped Shaft

The all-metal gear train resists heat and wear while handling heavier loads than plastic alternatives. A hardened steel D-shaped output shaft prevents coupler slippage and simplifies mounting with a single set screw. Pure copper windings and carbon brushes further reduce resistance and extend brush life.

Questions about this item

How fast will the 550 RPM output turn a wheel under load?

The gearbox delivers 550 RPM at the D-shaped steel shaft; actual wheel speed depends on the wheel diameter and the torque demanded by the vehicle weight.

What does the Hall encoder AB signal provide for a 12 V or 7.4 V build?

The incremental encoder outputs A and B phase pulses so a microcontroller can measure speed and direction for closed-loop control of Mecanum or balance platforms.

Will the D-shaped output shaft fit a standard 520 motor coupler?

Yes, the high-hardness steel D-shaft is designed for screw-fixed couplers used with 520-size gear motors.
