Forged Alloy Steel

 

 

Brief Introduction

The vibration range of low-voltage motors refers to the level of vibration intensity generated by the motor under normal operating conditions. Usually, parameters such as vibration speed and vibration acceleration are used to represent the size of the motor vibration range.

 

Standards for the vibration range of low-voltage motors
The standards for the vibration range of low-voltage motors are developed by the International Electrotechnical Commission (IEC) and the Chinese Society of Mechanical Engineering (CMES), among others. The IEC standard specifies the vibration levels of motors, which are divided into four levels: B, C, and D. Grade is different, Grade D is different. The CMES standard divides the vibration level into six levels, namely V1, V2, V3, V4, V5, and V6. V1 level is different, V6 level is different.

 

Factors affecting the vibration range of low-voltage motors
The magnitude of the vibration range of low-voltage motors is influenced by various factors, mainly including the operating status, structure, and quality of the motor. The operating state of the motor is the main factor affecting the vibration range. The vibration range of a motor may vary under different operating conditions such as no-load, load, and overload.
