Introduction Vibration and noise are the most common problems in motor testing and operation. There are many causes of vibration and noise, and it is not easy to distinguish them completely. In many cases, we will attribute vibration and noise caused by vibration to the rotor dynamic balancing link, and…
Introduction The permanent magnet synchronous motor is a synchronous motor that uses permanent magnets to establish an excitation magnetic field. Its stator generates a rotating magnetic field, and the rotor is made of permanent magnet materials. Once the permanent magnet motor loses its magnetism, basically you can only choose to…
I. Changes brought by the epidemic According to a report released by the United Nations[1], the economic growth rates of the United States and the European Union will be 0.4% and 0.2% respectively in 2023, Japan will be 1.5%, and the economies of the United Kingdom and Russia will experience…
Ⅰ. Introduction Nowadays more and more people choose to use PMSM(Permanent Magnet Synchronous Motor) because of its up to 20% energy-saving effect. Today I want to introduce the effect of Magnet Geometry and Tolerances on Motor Magnet Width. I hope it will be helpful to you. Ⅱ. Effect of the thickness…
DEFINITION Coreless DC motors are a type of DC motor that provides many advantages over traditional iron-core DC motors[1]. They are often used for highly dynamic movements and are ideal for use in robotic applications. APPLICATION Coreless DC motors are widely used in industrial automation. They can be used in…
Brushless DC (BLDC) motors are becoming more common in the automotive and industrial markets due to their high power density, efficiency, and reliability. A BLDC motor controller is required to operate a BLDC motor. The controller replaces the mechanical commutation system used by a Brush DC Motor with an electronic commutation…
Brushless DC motors (BLDC: Brushless Direct Current Motor), also known as electronically commutated motors (ECM or EC motors) or synchronous DC motors, are synchronous motors that use a direct current (DC) power supply. A brushless DC motor is essentially a permanent magnet synchronous motor with position feedback using a DC…
Permanent magnet synchronous motor (PMSM) must first understand two concepts, “permanent magnet” and “synchronous”. “Permanent magnet” means that the rotor of the motor is a permanent magnet, also called a permanent magnet; “synchronous” means that the frequency of the rotor and the frequency of the stator are the same, and its…
In recent years, switched reluctance motors have gradually entered the market, because the motor has the advantages of other motors do not have, so gradually become the main direction of the future development of the market, has been successfully used in various fields such as electric vehicle drive, general industry,…
01 Thanks to technological advances, integration is taking over the motor control market. Brushless DC motors (BLDC) and permanent magnet synchronous motors (PMSM) of all sizes and power densities are rapidly replacing motor topologies such as brushed AC/DC and AC induction. 02 BLDC/PSM motors are mechanically identical, with the…
