Notes for Purchasing Miniature DC Gear Motors

A miniature DC gear motor is a type of gear reduction motor, which is a widely used deceleration transmission device. Also known as a DC reduction gearbox, it is extensively applied in fields such as intelligent robots, intelligent medical equipment, automated industrial equipment, intelligent consumer electronics, smart home devices, communication equipment, and intelligent automotive equipment.

The models, parameters, and performances of miniature DC gear motors used in different industries and equipment vary. When selecting the model parameters of a miniature DC gear motor, what key points should be noted? Wansheng Motor has summarized the following points for reference:

Before purchasing a DC gear motor, determine its usage, application scenarios, and list factors such as environmental requirements, operating temperature, and backlash.
First, when determining the power, it is necessary to consider current, voltage, rotational speed, reduction ratio, transmission ratio, torque, load capacity, noise, transmission efficiency, and number of stages.
Next, determine the output shaft torque, installation method, and maintenance method of the DC gear motor.
Then, determine the input drive shaft speed and reduction ratio of the DC gear motor.
Select the DC gear motor according to the flange size of the DC gear motor. If the output shaft torque is insufficient, return to step 2 to re-match.
Determine the safety factor (SF).
The installation dimensions of the reducer and the motor.
The reduction ratio of the reducer.
The performance parameters of the motor, including voltage, power, rotational speed, number of stages, current, transmission ratio, load capacity, noise, and transmission efficiency.
The working environment and duty cycle of the motor.
Calculate the torque of the load; for the service life of the motor, torque calculation is very important, and attention should be paid to whether the maximum torque value (TP) during acceleration exceeds the maximum load torque of the motor.

When there is no suitable model parameter for selection of a miniature DC gear motor, Wansheng Motor can customize technical parameters according to everyone's needs based on their requirements.
