To prepare for an RC car event, you should first check with the track to see what they provide and what you need to bring. Many large races require you to bring your own table, chair, long extension cord, and power strip. It is also good to go over your…
What is a DC inverter fan? When we buy an electric fan, the manufacturer sales will refer to some high-end fans as DC inverter fans. In principle, the workflow of the so-called inverter technology is all about converting 50Hz alternating current (AC) to direct current (DC) and then to 30-130…
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…
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…
Current status of the brushless motor industry in the world The brushless motor industry is experiencing growth and expansion globally. The global brushless DC motors market was valued at USD 3443.05 million in 2020 and is expected to reach USD 5626.11 million by 2030, with a CAGR of 5% 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…
