Applications:

  • It is used to control the drive motor and auxiliary motors, such as air conditioning compressors and steering assist pumps. These devices can reduce the overall energy consumption of the vehicle and extend its range.
  • Its high power density, high efficiency, and wide speed control range can meet the power performance requirements of electric vehicles. In electric buses, it can also leverage its high energy efficiency, energy conservation, and high reliability features, thereby reducing operating costs.
  • To dissipate heat from core components such as batteries, motors, and electronic control units, specialized automotive cooling fans are installed.  These fans are designed to meet the needs of small vehicle spaces and the precise heat dissipation of multiple components. They are small in size, have more precise control, and can be linked with the VCU control system to achieve efficient and energy-saving operation, reducing noise and maintenance costs.
