Dc Gear Motor With Magnetic Linear Encoder jGA25-370 (170RPM-6V)

Description

The GA25-370 (170RPM - 6V) with a magnetic encoder is a precision-geared DC motor designed for robotics and automation requiring feedback for closed-loop control. At 6V, the 170RPM configuration typically utilizes a 34:1 reduction ratio to provide a balance of speed and mechanical strength.Technical SpecificationsOperating Voltage: 6V DC (functional from 3V to 9V).No-Load Speed: 170 RPM at 6V.Torque: Typical rated torque is approximately 0.6 kg·cm to 0.8 kg·cm, with a stall torque near 3.0 kg·cm for this speed variant.Current Draw: No-load current of ~100mA and a stall current of ~1.2A to 2.0A depending on the specific manufacturer's winding.Shaft: 4mm diameter D-shaped shaft for secure attachment.Magnetic Encoder DetailsThe integrated encoder uses a Hall-effect sensor and a magnetic disc to provide real-time feedback on position and speed.Resolution: Most standard encoders for this series provide 11 Pulses Per Revolution (PPR) from the motor shaft. After the 34:1 gearbox, this results in approximately 374 PPR at the output shaft.Output: Dual-channel (Phase A and B) quadrature square wave signals, allowing for detection of both speed and direction.Encoder Voltage: Typically requires a separate 3.3V to 5V DC supply.Wiring ConfigurationWhile colors may vary by brand, the standard 6-pin connector usually follows this layout: Red: Motor power (+).White: Motor power (-).Black: Encoder Ground (GND).Blue: Encoder Power (VCC: 3.3V-5V).Yellow: Signal Phase A.Green: Signal Phase B.
