How to choose the right DC motor for planetary reducer

Planetary reducers can be used in various high torque and low speed industries, such as electronic door locks, power tool fixtures and smart home systems.How to choose a suitable DC drive motor for planetary reducer?
For small DC motors used in planetary reducers, main parameters such as motor type, power supply, diameter, specification and model, working standard voltage, service life, operating noise, natural environment, full-load output speed and assembly method should be considered.
1) Types of DC motors
The motor of the planetary reducer is usually driven by a small motor, such as DC brush motor, brushless DC motor, coreless motor and stepper motor.Different drive motors have different advantages.If the brush DC motor has the characteristics of low cost and convenient speed change, the brush motor has the characteristics of long service life and low noise, and the hollow cup motor has the characteristics of high efficiency with high size and other characteristics, it can be selected according to the application equipment The function dictates the selection of an appropriate DC motor.
2) electricity
The power of the planetary reducer motor is usually about 0.1W-40W, and the power of the motor is affected by the size and application field.
3) Specifications and Models
The specifications and models of small motors are usually from mm to tens of mm.Appropriate specifications and models are selected according to the differences of application equipment.
4) Working standard voltage
The working standard voltage range of small motors can meet the requirements of most products in the market, about 1.5V-24V.The higher the working standard voltage, the faster the speed of the motor.
5) Service life
It refers to the continuous working time of the small motor at the rated value or at full load.The service life of brush motor DC motor for motor carbon brush can reach more than 1,000 hours, and the motor of brush motor coreless motor can reach more than 10,000 hours.If it is an application that must run continuously for a long time, you can choose a brush motor hollow cup.For example, brush motor DC motors are used in goods such as electronically controlled locks.
6) Push noise
Accurate noise measurements are expected when measured at rated current and speed.Generally, the motor noise of the micro planetary reducer is less than 40dB, which can meet the application requirements of most products.
7) Application scheme
The application scenarios of planetary gear motors are basically considered to operate at 30°C - 80°C, which can reach most application scenarios.
8) Full load output speed
The output speed of the small motor is very high.Just enter the AC voltage.The higher the operating voltage, the faster the speed.The torque and output speed can be estimated according to the transmission ratio of the planetary reducer.
