Description:
The Premium N20 Gear Motor 298:1 Ratio, 90 RPM, w/ Encoder is a high-precision miniature gear motor engineered for robotics, small automation, and DIY electronics projects. Combining compact design with high torque and integrated feedback, this motor delivers reliable performance in applications where space and precision matter.
It features a D-shaft output (3 mm) supported by a durable brass case and metal gears arranged in a straight-cut spur gearbox, ensuring long-lasting performance and smooth motion. The Brushed DC motor operates at a nominal voltage of 12 V (recommended range: 6–12 V), providing a no-load speed of 90 RPM with a no-load current of 70 mA. At stall, it delivers 70 oz-in of torque with a stall current of 1.6 A, offering reliable power for compact mechanical systems.
The motor integrates a magnetic Hall Effect encoder for precise feedback, delivering 3 cycles per motor shaft revolution and 3,575 countable events per output shaft revolution, in a relative quadrature format. This allows for accurate monitoring of speed and position, making it ideal for robotics, automation, and other applications requiring precision motion control. The encoder connects via a ZH Series JST 6-pin connector (1.5 mm pitch) for easy integration into electronic systems.
