In modern fitness and rehabilitation devices, micro DC motor for massage gun plays a key role. Micro DC motors are widely used in massage guns and various home appliances due to their high efficiency, low noise, compact structure, and reliability. This article provides a comprehensive analysis of motor principles, performance parameters, applications, customization solutions, and company capabilities.
The massage gun delivers high-frequency vibration to muscles and fascia for relaxation and fatigue relief. Its core driver is a low-noise DC motor, often using micro DC motor, mini DC motor, small DC motor models.
Key internal components include:
Battery pack: Typically two 3.7V 18650 lithium batteries in series for 7.4V operation; some high-power models support 12V or higher.
Linkage mechanism: An eccentric wheel drives the linkage to convert motor rotation into reciprocating vibration of the gun head.
Control circuit: The main chip adjusts motor speed and vibration strength for stable performance.
Motor: Usually RS-775 motors or similar high-speed brushed DC motors, reaching tens of thousands of RPM for high-frequency vibration.

Disassembling a massage gun reveals the motor application:
Remove the rear cover to see the circuit board, wiring, and main control chip.![]()
Remove the top cover to reveal the battery pack (1200mAh-2000mAh) and linkage mechanism.![]()
Remove the handle bottom to access the motor, usually a RS-775 brushed DC motor.![]()
Brushed DC motors have a simple structure, easy control, and low cost, ideal for small home or fitness devices. Slots on the motor casing show the brush assembly; higher voltage drives RPMs over 10,000+.
| Parameter | Description |
|---|---|
| Motor Type | RS-775 brushed DC motor |
| Rated Voltage | 7.4V-12V, up to 24V for high-power models |
| Rated Power | 15W-50W |
| No-load Speed | 10,000+ RPM |
| Noise | <60dB |
| Battery Capacity | 1200mAh-2000mAh |
| Vibration Frequency | 1500-3000 per minute |
These parameters determine vibration strength, runtime, and user comfort. RS-775 motors are widely used for their high speed, torque, and stability.
Beyond massage guns, 12V DC motors for home appliances are used in fans, blenders, vacuum cleaners, and other devices. Micro DC motors provide efficient power while maintaining low noise and long service life.
