The GB37Y3530-12V-251R is a high-performance geared motor equipped with an integrated quadrature encoder, designed to meet the demanding requirements of applications needing exceptional precision, robust power, and meticulous control. This sophisticated motor integrates a powerful 12V DC motor with a meticulously engineered 43.8:1 metal gearbox, which dramatically increases torque output while reducing the motor's speed for superior control. The integrated quadrature encoder offers high-resolution positional feedback, with a resolution of 16 counts per revolution of the motor shaft and 700 counts per revolution of the gearbox's output shaft. This high level of precision makes the motor ideal for applications where accurate control and monitoring of motor shaft rotation are critical. Designed with a compact yet sturdy build, the motor features a 0.61-inch long, 6 mm diameter D-shaped output shaft. This design ensures a secure and reliable connection to a variety of mechanical components, preventing slippage and enhancing compatibility with different setups. the face plate of the motor is equipped with six evenly spaced mounting holes threaded for M3 screws, providing versatile mounting options and facilitating easy integration into various mechanical systems. the motor is capable of initiating rotation at voltages as low as 1V, offering flexibility and efficiency across a range of operating conditions. The manufacturer advises caution in mounting, recommending a screw depth of no more than 3mm (1/8") to avoid contact with the internal gears, thus preserving the motor's integrity and performance.
