JGB37-520 Encoder-Equipped DC Gear Motor: Injecting “Precision Power” into DIY and Industrial Projects
—July 14, 2025
(Shenzhen) — With summer robot competitions and open-source hardware fever in full swing, the JGB37-520 “Hall-encoder DC gear motor” has become a breakout star on maker forums and e-commerce platforms at home and abroad. Featuring a 37 mm metal gearbox paired with an AB-phase incremental Hall encoder, the motor offers 12 V/24 V wide-range power, a 30:1 reduction ratio, and 11 PPR high-resolution feedback—making it the go-to choice for self-balancing cars, smart sorting robots, and more.
Key Specs at a Glance
• Supply: 6 V–24 V DC, selectable
• No-load speed: ≈200 RPM (12 V, 30:1 gear ratio)
• Encoder output: AB quadrature pulses, 330 pulses/rev per channel, 1,320 counts/rev after 4× decoding
• Wiring: 6-color leads (red/white = motor ±, blue/black = encoder power/GND, yellow/green = A/B signals)
