What are the characteristics of the gears of different materials of the miniature gear motor?

Micro gear motors are frequently utilized in high-torque products. Micro gear motors' gears can be made of plastic, powder metal, carburized steel, etc. The advantages of gears of different materials are also different in various aspects.

1. a motor with a micro-reducer made of powder metal

This type of gear is frequently used and can achieve the necessary dimensional accuracy by a single forming and finishing operation alone, requiring no additional post-processing. Other drawbacks include poor transmission stability, weak contact strength of gear teeth, inability to transmit large torques, transmission noise, and gear teeth with lower bending and shear resistance than those produced by conventional machining. As a result, the micro low-power motor is typically utilized in conjunction with the powder metallurgy gear motor.

2. Micro gear motor with carbureted steel gears

Rarely do micromotors employ gear reducers manufactured of this material. They are strong, durable, and hard enough to significantly lower the likelihood of deformation and cracking in carburized parts.

3. Micro gear motor with plastic gear

The main advantages are their light weight, low cost, and outstanding chemical stability, which can successfully withstand acid, alkali, or organic solvent corrosion. They also have excellent wear resistance and self-lubrication, and the transmission is quiet and hushed. The plastic gear motor has good electrical insulation, but it has weak thermal diffusivity. It will be quite clear if it is a sizable gear motor. The other is the plastic gear motor's accuracy of the gears, which is based on the performance of the plastic and the precision of the mold.
