Motor interference refers to the phenomenon that the electromagnetic radiation emitted by the motor when it is running interferes with the electronic equipment, causing the performance, reliability and stability of the equipment to be damaged. Motor interference will not only affect the normal operation of the equipment, but also cause equipment damage or failure, causing trouble and loss to the use of the equipment.

1. Causes of motor interference

The main causes of motor interference are as follows:

1. Electromagnetic radiation of the motor itself: The motor will generate magnetic fields and electric fields when it is running. These magnetic fields and electric fields will generate electromagnetic radiation and interfere with surrounding electronic equipment.

2. Power supply of the motor: There may be power supply interference in the power supply line of the motor, causing the electromagnetic radiation of the motor to interfere with surrounding electronic equipment.

3. Grounding of the motor: There is a problem with the grounding of the motor, causing the electromagnetic radiation of the motor to interfere with surrounding electronic equipment.

2. How to prevent motor interference

In order to prevent motor interference, the following measures can be taken:

1. Choose a low-radiation motor: When purchasing a motor, you should choose a low-radiation motor, which can reduce the interference of the motor to surrounding electronic equipment.

2. Isolation of the motor: Isolate the motor from the surrounding electronic equipment,

3. Optimize the power supply line of the motor: Optimize the power supply line of the motor to reduce power supply interference,

4. Optimize the grounding of the motor: Optimize the grounding of the motor to reduce the interference of the motor to the surrounding electronic equipment.

III. Solutions to motor interference

If motor interference has occurred, the following methods can be used to solve it:

1. Use filters: Adding filters to the power supply line of the motor can effectively reduce power supply interference, thereby reducing the interference of the motor to the surrounding electronic equipment.

2. Use shielding materials: For electronic equipment that needs to be shielded, shielding materials can be used to isolate the electronic equipment from the motor to reduce the interference of the motor to the electronic equipment.

3. Optimize grounding: Optimize the grounding of the motor and electronic equipment to effectively reduce the interference of the motor to the electronic equipment.

4. Adjust the position of the motor: Adjust the position of the motor to reduce the interference of the motor to the surrounding electronic equipment.

Motor interference is a common problem in electronic equipment, but it can be avoided and solved by some simple methods. When purchasing a motor, you should choose a motor with low radiation, isolate the motor from surrounding electronic equipment, optimize the motor's power line and grounding, and if motor interference has occurred, you can use filters, shielding materials, optimize grounding, and adjust the position of the motor to solve it. In practical applications, you need to choose the appropriate method according to the specific situation to achieve the best anti-interference effect.
