PWM DC motor governor provides 5V to 35V speed regulation with 5A output current, 90W output power and 20kHz frequency for controlling small DC motors, featuring compact dimensions of 30mm x 26mm x 14mm
PWM DC Motor Speed Governor for 5V to 35V Applications with 5A Output

This PWM DC motor governor provides precise speed control for small DC motors operating between 4.5V and 35V. With a maximum output current of 5A and 90W power handling capability, it suits various projects requiring regulated motor speed. The 20kHz PWM frequency ensures smooth motor operation while the compact 30mm x 26mm x 14mm dimensions make it suitable for space-constrained applications. Operating on DC voltage only, this governor cannot be connected directly to AC mains power and includes features for safe operation.
Features and Construction

The DC motor governor is designed for controlling small DC motors with specific technical specifications that determine its applications and limitations.
Material and Build
Constructed from electronic components arranged on a PCB, this governor is designed for DC motor control applications. The build includes reverse polarity protection to prevent damage from incorrect connections. The compact construction at 30mm x 26mm x 14mm makes it suitable for integration into various projects without requiring excessive space.
Size and Practical Fit
With dimensions of 30mm length, 26mm width and 14mm height, this governor fits into compact spaces. The small footprint allows installation in tight project enclosures while still providing 5A output capability. The physical size reflects its suitability for small to medium DC motor applications rather than industrial-scale equipment.
Uses and Placement

The governor's technical specifications determine its appropriate applications across different settings where DC motor speed control is required.
Event or Professional Use
In professional settings, this governor can control DC motors in prototype development, small machinery, and testing equipment. The 4.5V to 35V operating range covers common DC motor voltages, while the 5A output supports motors of various sizes. The precise PWM control allows for accurate speed regulation in demonstration equipment and working models.
Everyday Home Use
For home projects, this governor suits hobbyist applications like model railways, robotics, and DIY automation. The ability to control motor direction by adjusting wire sequence provides flexibility for different project requirements. The compact size makes it suitable for integration into finished projects without dominating the design.
Benefits and Buying Value

The governor offers practical advantages for users needing reliable DC motor speed control within specified technical limits.
Reuse and Low Maintenance
With proper connection to DC power sources only and attention to polarity, this governor requires minimal maintenance. The 7μA standby current ensures low power consumption when not actively controlling motors. Following the usage instructions regarding voltage range and connection types supports continued reliable operation.
Why Choose This Product
This governor provides specific technical capabilities including 5V to 35V operation, 5A output, and 90W power handling in a compact package. The 20kHz PWM frequency offers smooth motor control, while the adjustable duty cycle from 1% to 100% allows precise speed regulation. These specifications make it suitable for projects requiring controlled DC motor operation within these parameters.
