Background
The hair drier generally refers to a hair drier brushless DC motor which is composed of a motor main body and a driver and is a typical electromechanical integrated product. The blower is composed of a group of electric heating wires and a high-speed small fan. When the fan is electrified, the heating wire can generate heat, and the air blown out by the fan passes through the heating wire and is changed into hot air. If only the small fan rotates and the heating wire is not hot, only wind but not heat is blown out.
Because the brushless DC motor is operated in a self-control mode, a starting winding is not additionally arranged on a rotor like a synchronous motor which is started under the condition of heavy load under the condition of frequency conversion and speed regulation, and oscillation and step-out can not be generated when the load suddenly changes. The permanent magnet of the brushless DC motor with medium and small capacity is mostly made of rare earth neodymium iron boron material with high magnetic energy level. Therefore, the volume of the rare earth permanent magnet brushless motor is reduced by one machine seat number compared with that of a same-capacity three-phase asynchronous motor.
