What are the applications of brushless DC motors in automobiles?

Instead of using a commutator to regulate the current in the coils, a brushless DC motor uses an electronic commutator to pass the current, which creates an AC signal that causes the motor to drive. Lorentz's law of force states that whenever a current-carrying conductor is placed in a magnetic field, it experiences a force. Due to the reaction force, the magnets will experience equal and opposite forces. So what are the applications of brushless DC motors in automobiles? Let us introduce Vshida micro motors to you.

1. A automobile air purifier's brushless DC motor. Centrifugal fan blades are typically driven by brushless DC motors in vehicle-mounted purifiers in order to exhaust contaminated air. The motor circuit plan determines the brushless DC motor body, and a two-phase bridge commutation driving circuit is frequently employed. On the core teeth, the inner stator winding can be wound more easily. The stator and stator windings are housed inside the outer rotor assembly of the brushless DC motor. An application-specific integrated circuit (ASIC) with a straightforward structure that performs control and protection tasks is used in the commutation drive circuit.

2. A wheel drive DC motor with a brushless motor. Nowadays, the four major categories of motors that are used to drive wheels are brushless DC motors, AC induction motors, DC brush motors, and reluctance motors. After some use, the brushless DC motor is thought to have clear advantages. Four separate hub motors directly power the electric car. The inverter abandons the mechanical commutator and brushes in favor of electrical commutation. Its structure is simple and practical for high-speed operation and does not interfere with the motor body when changing tires.

3. Automotive air conditioner brushless DC motors. For car air conditioners, the development of low-voltage and high-current brushless DC motors can address the drawbacks of brushed DC motors, such as high noise, a brief lifespan, and challenging maintenance, and enhance the motor's performance. The structure's limitations make the brushless DC motor's design more challenging. A two-slot construction makes up the stator piercing. The rotor is a 4-pole structure with permanent magnets attached to the surface, and because it is a low-voltage and high-current type, two wires are coiled in parallel to lower the wire diameter and ensure that the current density won't be too high. NdFeB, a material for rare earth permanent magnets, is chosen.

The above is the application of brushless DC motors in automobiles that we have introduced to you. For more news and information, please feel free to consult us. Looking forward to your inquiry.
