130 Brushed Motor Series 5V 12V 130SH DC Motor With Copper Pinion Gear
KC-130SH 130 Brushed Motor With Copper Pinion Gear
The KC-130SH series is a 130 brushed motor configured with a factory-mounted copper pinion gear for direct integration into small mechanical drive assemblies. The motor uses a conventional DC brush structure and a 20.4 mm-class metal can, providing a practical interface for OEM equipment where the motor output must transfer directly into an external gear train. This configuration can be used as a 130 dc motor with copper gear in mechanisms that require defined pinion dimensions rather than a plain output shaft.
Two electrical versions are available within the listed series. KC-130SH-15150 is configured as a 5v 130 dc motor for lower-voltage systems, while KC-130SH-19110 provides a 12v 130 dc motor option for applications requiring substantially higher rotational speed and output power. The dimensional platform remains suitable for equipment designed around a 130 size brushed motor, allowing engineers to compare electrical performance without redesigning the basic motor envelope.

130SH Motor Dimensional Drawing
Engineering Selection Considerations
The 5 V model operates at a lower speed and current level, making it more compatible with battery-powered devices and moderate-speed mechanisms. The 12 V version operates at a substantially higher no-load speed and provides greater stall torque and output power. Engineers should therefore select the motor according to available supply voltage, required operating speed, expected mechanical load and driver current capacity rather than voltage alone.
The integrated copper gear also differentiates this assembly from a standard 130SH dc motor with a plain shaft. A 130 motor with pinion gear can simplify mechanical integration when the mating gearbox or transmission is designed around a defined gear diameter and engagement length. Proper center distance, backlash, shaft alignment and allowable stall duration should be verified during equipment development.
130 Brushed Motor Performance Advantages
- Copper pinion gear provides a defined mechanical interface for direct engagement with compatible transmission components.
- 5 V and 12 V configurations support different supply architectures while retaining the same 130SH mechanical format.
- Ø20.4 mm motor can and 25 mm body length provide established dimensional references for equipment integration.
- Available performance ranges support selection between moderate-speed operation and higher-speed drive requirements.
- Specified shaft, pinion and terminal dimensions simplify tolerance checks during OEM mechanical design.
