      1.Brushless DC Motors for Automotive Wheel Drive:<\/strong><\/h4>\n

      Currently, motor types for vehicle wheel drive can be roughly divided into four categories: brushed DC motors, AC induction motors, brushless DC motors, and reluctance motors. Through practical experience, it has been found that brushless DC motors have distinct advantages. Electric vehicles employ four independently driven wheel motors, directly driven by inverters for electronic commutation, eliminating the need for mechanical commutators and brushes. This structure facilitates high-speed operation and doesn’t affect the motor itself during tire replacement, making it simple and convenient.<\/p>\n

      2. Brushless DC Motors for Automotive Air Conditioning:<\/strong><\/h4>\n

      Developing low-voltage, high-current brushless DC motors for automotive air conditioning addresses issues such as high noise, short lifespan, and maintenance difficulties associated with traditional brushed DC motors. With a rated voltage of 2V, the design complexity increases due to structural constraints. The stator core adopts a 2-slot structure, and as it is a low-voltage, high-current type, dual winding is used to prevent excessively high current density, reducing wire diameter. The rotor adopts a surface permanent magnet pasted 4-pole structure, using neodymium iron boron rare-earth magnet material for enhanced performance.<\/p>\n

      3.Brushless DC Motors for Automotive Purifiers:<\/strong><\/h4>\n

      Automotive purifiers commonly use brushless DC motors to drive centrifugal fans to expel polluted air. The brushless DC motor body is determined based on the motor circuit scheme, often using a two-phase bridge commutation drive circuit. The inner stator winding can be conveniently wound around the teeth of the iron core. The motor is designed as an external rotor structure, with the stator and stator windings placed inside the rotor. The commutation drive circuit employs a dedicated integrated circuit (ASIC) for simplicity and includes control and protection functions.<\/p>\n
