Product Description

⚙️ 370 Motor with GM3246 Gearbox and Encoder

The KS-GM3246-370 combines a 370 motor, metal reduction gearbox and encoder-ready configuration for compact motion systems that require controlled speed and higher output torque. The platform supports 8 VDC, 12 VDC and 24 VDC motor variants, while the GM3246 gearbox provides reduction ratios from 37.3:1 to 2900:1. This range allows engineers to configure the same mechanical platform for relatively fast transmission or low-speed, high-torque operation.

Compared with a standalone 370 brushed motor, the gearbox converts motor speed into usable output torque without requiring a larger drive package. The available data covers the motor and gearbox separately so engineers can evaluate the operating point before selecting a complete 370 dc gear motor. Encoder integration can support applications that need rotational feedback, but encoder resolution and electrical interface should be confirmed for each project.

🔩 Engineering Selection and B2B Customization

The main design choice is the relationship between output speed, torque and reduction ratio. A lower ratio keeps more output speed, while a higher ratio increases usable gearbox torque and suits mechanisms that require slow, controlled movement. Across the supplied configurations, the 370 motor with gearbox covers reductions from 37.3:1 to 2900:1 and output speeds extending from approximately 2 rpm to 211.8 rpm.

For production projects, specify the operating voltage, target output speed, continuous load torque, shaft geometry, mounting interface, connector and feedback requirements. These inputs allow the motor, ratio and encoder configuration to match the actual mechanism rather than relying on no-load speed alone. Custom shaft length, D-cut geometry, wiring, connector orientation and encoder interface can also be reviewed for OEM or ODM assemblies. For high-reduction versions, verify duty cycle and continuous torque separately from the listed 15 kg·cm stall torque limit.
