Introduction to the widespread application of brushless DC motors in automobiles.
Today, TOPBAND MOTOR will introduce the widespread application of brushless DC motors in automobiles. Let's take a look together~
1、 The automotive BLDC motor market is quietly emerging
In recent years, with the continuous maturity of automotive electronic control technology, the requirements for automotive comfort and safety have also been increasing. The application of automotive micro motors, which are used for action execution and stroke control in control systems, has become increasingly widespread, giving rise to a technology that many people may not have noticed yet. This is the widespread application of brushless DC motors (BLDC) in automobiles, and its market is quietly rising and growing rapidly.
Automotive control motors usually include brushed DC motors, stepper motors, hollow core motors, brushless DC motors (BLDC), etc. Brushed DC motors have been widely used in various vehicle systems, such as air conditioning blowers, electric fans, wipers, electric rearview mirrors, and power windows. However, due to inherent problems such as short brush life, poor EMI performance, and low efficiency, an increasing number of vehicles have replaced brushed DC motors with brushless DC (BLDC) motors.
Compared to brushed DC motors, BLDC has faster speed, higher efficiency, lower noise, and higher operational reliability, but also requires complex electronic control. In today's increasingly sophisticated electronic control technology, the brushless DC motor market has rapidly expanded. In addition to traditional vehicle fuel pumps, cooling water pumps, HVAC blowers, and electronic fans, it has been widely used in autonomous driving and new energy vehicles, such as air cooling systems for MCU/EMS/battery systems, electronic water pumps in water cooling systems, electronic compressors for air conditioning systems, electronic vacuum pumps for brake assist, AFS, seat adjustment, and electric power steering EPS, among others. The following table shows the usage of motors in typical new energy vehicles. In short, motors are required wherever there is a driving mechanism for movement, and brushless motors are more commonly used.
2、 The competitive landscape of automotive BLDC motors
From the perspective of market trends, Asia has developed rapidly due to Japan's leadership; Japan and China are the main countries in Asia producing brushless motors. Due to its advanced technology, Japan has established brushless motor manufacturers in multiple regions and countries around the world, mainly producing high-end brushless motor products. In recent years, due to the advantages of raw materials and human resources, brushless motors in China have also begun to develop rapidly. However, due to a late start, the technical foundation of brushless motors is generally low, and most of the brushless motors produced are mainly mid to low end products. With the introduction of China's energy-saving motor subsidy policy and technological progress, the brushless motor market in China will further expand.
For Europe, due to its early start, many European countries such as Germany and Switzerland have mastered the core technology of brushless motor technology. With the increasing demand for high-end brushless motors in the global market, the proportion of brushless motors in Europe will maintain a slow upward trend.
In recent years, automotive parts research and development giants have accumulated a large number of achievements in the automotive control motor industry through research and development, building technological barriers in this field. But excellent brushless motor research and manufacturing enterprises such as Shunli have also emerged in China. They have independently developed brushless motor products such as steering assist brushless motors, brushless motor fans, and electronic water pumps that can compete with international brands.
According to data, the Asian market leads the world with a market size of 46.94%, followed by the United States with a share of 21.08%.
Alright, the above is an introduction to the widespread application of brushless DC motors in automobiles, hoping to help everyone~
