Description

Novel brushless electric fan heater

Technical Field

The invention belongs to the technical field of fans for new energy automobiles, and particularly relates to a novel brushless fan heater.

Background

At present, the fan heater for realizing air replacement in domestic automobile air conditioners and automobile cooling and heating systems adopts a motor with a commutator and an electric brush, which is mature in domestic and foreign markets, as a driving system, and is realized by additionally arranging an impeller and a volute (a mounting seat), wherein the driving motor is commonly called as a brush motor. The driving principle of the motor is that the electrified conductor is stressed in a magnetic field to generate torque, so that the rotor runs and simultaneously drives the impeller to run, and electric energy is converted into mechanical energy. The key technology in the middle is that the electric conductor in the rotor needs to realize continuous positive and negative change (reversing), so that the rotor can continuously generate torsion in the same direction, and the fan impeller is driven to rotate to realize the air blowing and sucking functions (air replacement) of the fan. At present, the commutation of the fan heater motor for the automobile in China realizes the switching-commutation of the positive pole and the negative pole by the contact of an electric brush with different commutator segments on a commutator. The above reversing mode of the conventional motor belongs to mechanical reversing, and the fan driven by the mechanical reversing motor has the defects of mechanical noise, sparks, electromagnetic interference (EMC) and low service life (the brush is a wear part and is worn out, namely the service life of the motor is over) for a long time.

Therefore, there is a need to design a new brushless fan heater to solve the above problems.
