37mm Spur Gear Motor

♦ Basic Info:

Diameter: 37mm

Body Length: 36mm

Operating Voltage: 3V DC-26V DC

♦ Key advantages

  • Standard 37mm gearbox envelope with multiple voltage windows: Ø37mm gearmotor with 36mm body length, operating range 3–26V DC. Reference builds cover low-voltage (3–8V, 50:1), 12V class (10–14V, 150:1), and 24V class (22–26V, 490:1) projects.
  • Ratio selection tied to gearbox length (easy mechanical check): Gearbox lengths 19 / 24 / 26.5 / 29 mm correspond to common ratio groups (10:1, 50/70/90:1, 150/210/270:1, 490:1). Engineers can confirm axial space and ratio in one step.
  • Production configuration can be frozen on drawing + datasheet: Shaft geometry, target speed/torque point, lead wires/connectors, gear-on-shaft, and encoder option are configurable for OEM orders to support repeat purchasing and consistent incoming inspection.

♦ Applications:

Vending machine/ Garden lock/ Actuator

/ Home Appliance/ Medical devices/

Security equipment/ Industrial Tools

Product introduction

This 37mm spur gear motor is a brushed DC gearmotor platform designed around a fixed Ø37mm gearbox and a 36mm body length. The electrical operating range is 3–26V DC, supporting both low-voltage battery designs and 12V/24V systems depending on winding and ratio selection.

For quick selection, the series provides reference configurations such as 50:1 (3–8V), 150:1 (10–14V), and 490:1 (22–26V). Each ratio group is associated with a defined gearbox length (19–29mm), which helps mechanical engineers verify the stack-up early and avoid bracket redesign later. Performance tables are available for no-load, loaded, and stall points; these can be used to size the driver and set current limits.

For OEM production, we support shaft customization, wiring/connector options, and encoder integration when feedback control is required. Typical applications include vending equipment, garden locks, actuators, home appliances, and industrial tools.

FAQs

Q1. Can I use this 37mm gearmotor on both 12V and 24V systems?

Yes. The platform supports 3–26V DC, and the correct winding + ratio is selected based on your supply voltage and required output speed/torque.

Q2. How do I choose between 50:1, 150:1, and 490:1?

Select based on required output RPM under load and torque margin. Lower ratios increase speed; higher ratios increase torque and reduce speed. Share load torque, target RPM, and duty cycle for a recommendation.

Q3. What can be customized for OEM orders?

Common options include shaft length/shape, lead wires/connectors, target performance point, adding a gear on the shaft, and an encoder option for feedback control.
