SPIDER Automation | MY6812 12V 150W Brushed DC Motor | 2750RPM Chain Drive Motor
The MY6812 12V 150W Brushed DC Motor is designed for compact electric drive systems requiring a high-speed rotary output and chain-based mechanical transmission. Operating on a 12V DC supply, this motor has a rated rotational speed of 2750 RPM and is suitable for integration into compatible small electric vehicles, scooters, kiddies’ carts, robotics projects and DIY automation mechanisms.
The motor is equipped with a 9-tooth sprocket for #25 chain, allowing rotational power to be transferred to a driven sprocket or compatible chain mechanism. Its 8mm D-cut shaft uses a circlip-retained sprocket arrangement, making sprocket removal possible when mechanical modification or maintenance is required.
The motor also features ball-bearing construction to support rotating shaft operation. Its compact drive arrangement makes it useful for projects where a 12V brushed motor and chain transmission are required.
Technical Features & Functional Characteristics
- Brushed DC Motor Design: Uses a brushed DC motor configuration for conventional DC-powered drive applications.
- 150W Power Rating: Designed for mechanical drive applications requiring a 150W motor rating.
- High-Speed Rotation: The rated rotational speed of 2750 RPM supports compatible chain-drive mechanisms and rotary applications.
- 9-Tooth Chain Sprocket: The integrated sprocket is designed for #25 chain transmission.
- Ball-Bearing Construction: Ball bearings support the motor’s rotating assembly.
- 8mm D-Cut Output Shaft: Provides a shaft profile for the sprocket mounting arrangement.
- Circlip-Retained Sprocket: The sprocket is secured using a circlip and can be removed after releasing the retaining clip.
- Mechanical Drive Integration: Can be incorporated into compatible chain-driven mechanisms, subject to mounting and transmission requirements.
Chain Drive & Shaft Configuration
The MY6812 motor comes with a 9-tooth sprocket compatible with #25 chain. This arrangement allows the motor to drive a secondary sprocket through a matching chain, making it suitable for compact vehicle and mechanical drive assemblies.
- Drive Type: Chain drive.
- Sprocket: 9 teeth.
- Chain Compatibility: #25 chain.
- Output Shaft: 8mm D-cut shaft.
- Sprocket Retention: Circlip-mounted arrangement.
The sprocket can be removed by first removing the retaining circlip and then sliding the sprocket off the shaft. Any replacement sprocket must match the shaft profile and the intended chain specification.

Connection & Operating Recommendations
For reliable integration, operate the MY6812 motor with a suitable 12V DC power system and ensure that the chain transmission, mounting arrangement and mechanical load are compatible with the motor’s ratings.
- Use a Suitable 12V DC Supply: Select a power source and motor controller appropriate for a 12V, 150W brushed motor. The theoretical current corresponding to 150W at 12V is approximately 12.5A; actual operating and starting current can differ depending on load and motor conditions.
- Select a Compatible Controller: Use a brushed DC motor controller designed for the motor’s voltage and current requirements, with adequate allowance for starting and load-related current.
- Match the Chain: Use a compatible #25 chain with the supplied 9-tooth sprocket to maintain correct mechanical engagement.
- Align the Drive System: Keep the motor sprocket and driven sprocket properly aligned to reduce uneven chain wear and mechanical stress.
- Set Appropriate Chain Tension: Avoid excessive slack or over-tightening, as incorrect tension can affect transmission performance and place additional load on the motor shaft and bearings.
- Secure the Motor Mounting: Use a rigid mounting arrangement suitable for the motor’s operating forces and vibration.
- Remove the Sprocket Carefully: Release the circlip before sliding the sprocket off the 8mm D-cut shaft. Use suitable circlip tools to avoid damaging the retaining clip or shaft.
- Manage Operating Load: Avoid exceeding the motor’s intended power and mechanical load requirements. Provide suitable ventilation and avoid prolonged operation under stalled or overloaded conditions.
