What is Small DC Gear Motor?

Publish Time: Author: Site Editor Visit: 423

Small DC gear motors, namely gear reducers, are ordinary DC motors coupled with matching micro gearboxes. The role of the gearbox is to provide lower speed and higher torque. Gearboxes with different gear ratios can simultaneously provide different speeds and torques. This will increase the use of DC motors significantly in the automation industry. A small DC gear motor refers to the combination of reducer and motor, also commonly known as a small gear motor. It often features high transmission precision, compact size, low-noise, durability, low energy consumption, and long service life. 

Small DC gear motors are widely used, and their technical parameters can be customized by ZHAOWEI according to the application. Customizable range of DC motor models with gearbox includes:

Diameter: 3.4mm-38 mm
Voltage: 3V-24V
Noise: ≤45dB
Output power: ﹤50W
Output speed: 5-2000rpm
Gear ratio: 5-1500
Output torque:
Transmission precision: 1-2 arcmin

Functions of Small DC Gear Motors:

The main purpose of the DC gear motor is to reduce the output speed. Since the motor is equipped with a reducer, the speed of the motor can be reduced. Furthermore, it can not only reduce the speed, but also increase the output torque of the motor. It also can reduce the inertia of the load. The gear ratio represents the ratio of output torque to input torque. The output torque here cannot exceed the rated torque of the gear motor.  

Main Types of Small DC Gear Motors:

  1. According to the type of transmission: gear motor, planetary gear motor, worm and worm gear motor;
  2. According togear shape: cylindrical gear motor, bevel gear motor, conical cylindrical gear motor;
  3. According to transmission stages: single-stage gear motor, multi-stage gear motor;
  4. According to motor type: BLDC gear motor, Brushed DC gear motor;

Application of Small DC Gear Motors:

Small DC gear motors are widely used in intelligent automobiles, intelligent communication, intelligent robot, intelligent logistics, smart city, electronic products, personal care tools, industrial automation equipment, smart home, precision instrument, outdoor adventure equipment, and photography equipment, etc.
