With the more and more widespread use of DC brushless motors, their performance has also improved to a certain extent. However, various failures will also be encountered in the process of using the BLDC motor. Common problems with brushless motors include Overheating, Power loss, Difficulty starting or controlling the motor,…
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…
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…
Introduction of high speed motor High-speed motor usually refers to the motor whose speed exceeds 10000 r / min. High-speed motors are small in size, can be directly connected to high-speed loads, eliminating the need for traditional mechanical speed increase devices, reducing system noise and improving system transmission efficiency. Currently,…
The term brushless motor may be heard by few partners in life, but it is nowhere to be found in our daily life. This article will lead you to see in which corner of life the infinite motor is hidden! 1、Kitchen appliances The kitchen is full of electrical appliances, and…
1. What do you mean by electric motor? Motor is the part that converts battery electric energy into mechanical energy and drives the wheels of electric vehicles to rotate. 2. What is winding? Armature winding is the core part of a DC motor, which is a coil wound by copper…
A, the classification of hollow cup motor hollow cup motor is divided into two kinds of brushed and brushless, brushed hollow cup motor rotor without iron core, brushless hollow cup motor stator without iron core. Brush hollow cup is a wire cup plus commutator as the rotor of the motor,…
Captain’s Log. Day eight of quarantine. Work has been busy; I’m grateful for the technology we have to collaborate and continue business during this time. I have walked around the block seven times today. I wonder how many days in a row I can eat frozen jalapeno poppers for lunch…
