Winding is one of the most important processes in the manufacturing process of electric motors, and with the development of electric motors, different “discipline categories” have been created.[1] Stator winding is distinguished by the formation of magnetic poles The stator winding can be divided into two types: The salient type…
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…
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…
1, structural differences, brushless DC motors usually rotor poles using tile magnets, after the magnetic circuit design, you can get trapezoidal wave of air gap magnetic density, stator winding more concentrated whole pitch winding, so the induction counter-electromotive force is also trapezoidal wave. Brushless DC motor control requires position information…
The engineering staff at BLDC Designs has experience in the design and manufacturing of the following types of motors for various industries and applications: Slotted Stator Motors with inner rotating rotors (i.e. In-Runners) Slotted Stator Motors with outer rotating rotors (i.e Out-Runners) Radial Flux, Inner or Outer Rotating Slotless (Coreless)…
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…
