A Solution to the Noise of Pusher DC Motor

2019-11-14 13:54

As we all know, the use of push rod DC motor is very wide, often used in automotive systems, medical equipment, smart home, household appliances, office automation, drones, robots, digital equipment and other fields, the application of push rod DC motor is too numerous to mention, can be said to be everywhere. However, people often worry that the noise of the push rod DC motor is relatively large, but the mechanical noise cannot be completely eliminated. Therefore, we need a solution to the noise of the push rod DC motor. Today, I will talk about it. A solution to the noise of a push rod DC motor.

Motor is one of the sound sources of noise, and it is widely used in household appliances, automobiles, office appliances, workers, farmers and medicine, and is closely related to people's lives. Therefore, it is the responsibility of each designer and producer to minimize the noise of the motor, produce low-noise motors, and create a comfortable and quiet living environment for people.
 
Push rod DC motor noise production is mainly bearing noise. Due to the improper size of the bearing and the bearing chamber, noise is generated when the motor rotor rotates together. The ball is not round or mixed with debris, causing them to collide with each other to produce vibration and noise. The improper value of the pre-pressure of the bearing leads to micro-vibration of the raceway surface and noise.
 
Only true motor for these studies a perfect push rod DC motor noise solution, generally should be sealed bearings to prevent debris from entering. When the bearing is assembled, it should be demagnetized and cleaned to remove oil and iron filings. The noise of the bearing after cleaning is generally 2 ~ 3dB lower than that of the bearing before cleaning. Grease to clean, can not contain dust, impurities.

Hub Motor System and Characteristic Analysis

The in-wheel motor system is usually called the in-wheel motor, and some researchers call it the wheel motor, electric wheel or wheel motor. The English name is mostly "in-wheel motor", and it is also called "wheel direct drive motors" and "wheel motor. In fact, the above terms are strictly inaccurate. The "hub motor, wheel motor and wheel motor" all focus on the motor, while the "electric wheel" focuses on the wheel. From the system point of view, we should refer to the integrated multi-functional system formed by the tight integration of the drive motor and the wheel, that is, the "integrated motor and wheel system". Analysis of the characteristics of the in-wheel motor system Generally, electric vehicles use a centralized motor-driven power system structure. This type of structure has the following advantages:

Micromotors, also known as electric motors, are represented by the letter M in the circuit. Its main function is to generate driving torque as a power source for electrical appliances or small machinery. A micromotor is a device that converts electrical energy into mechanical energy. Most micro-motors use the principle of homopolar repulsion, heteropolar absorption and electromagnetism to complete the conversion of electrical energy and mechanical energy.
