Motor noise is a significant factor affecting motor performance and operating environment. It primarily consists of airborne noise, mechanical noise, and electromagnetic noise. Each noise type has its own unique source and control methods. The following is a detailed analysis of these noise types, a

General use standard asynchronous motors are designed for constant frequency and constant voltage operation. They cannot fully meet the requirements of speed regulation by a variable-frequency drive (VFD), so they cannot be used as variable-frequency motors.The impact of a VFD on a motor mainly focu

Why do others' motors last five or eight years without breaking down, while yours is constantly in need of repair?It's not because the motor is poor quality; it's likely you've stepped on these "invisible killers"!Today, we'll uncover the four main culprits of motor shortevity. Learn how to avoid th

Ⅰ. Introduction In the second half of 2023, we will work with one of food company in Jiangxi, China to carry out motor transformation, which will be used until the end of February 2024. We will solve the problems raised by customers who are dissatisfied with the equipment after on-site working condi

Ⅰ. Introduction Motors are fundamental components of a wide range of industrial, commercial and household appliances. To ensure the life and reliability of motors, high-quality insulation materials are required to prevent failures caused by electrical, mechanical and thermal stresses. The insulation

Ⅰ、Introduction Synchronous Reluctance Motors (SynRMs) are a class of electric motors that rely on reluctance to produce motion, meaning they do not use permanent magnets or winding excitation to generate a magnetic field. These motors offer a simple, robust, and cost-effective alternative to convent
