Abstract

A dust collector motor with Hall devices in the technical field of motors comprises a motor housing, a motor shaft, a flow guide device, a fan impeller, a magnetic conductive ring, Hall devices, a stator bracket and a stator device. The motor housing comprises a motor front cover, a motor shell and a motor rear cover, and the motor front cover, the motor shell and the motor rear cover are connected together through bolts. The motor shaft is arranged on the axis of the motor housing. The fan impeller is arranged in the flow guide plate and connected with one end of the motor shaft. The magneticconductive ring is arranged on the outer edge of the middle of the motor shaft. The Hall devices are arranged on the outer edge of the middle of the motor shaft and abut against the magnetic conductive ring. According to the invention, the Hall signal of the motor can be monitored through the Hall devices, and the motor can be effectively controlled. The dust collector motor is reasonable in design, simple in structure, and the technical scheme is suitable for optimal design of a dust collector motor.

Description

technical field [0001] The invention relates to a brushless motor in the technical field of motors, in particular to a vacuum cleaner motor with a guide cavity and a Hall device. Background technique [0002] Vacuum cleaners are mainly composed of three parts: dust collection, dust collection, and dust filtration, generally including series commutator motors, centrifugal fans, dust filters (bags) and dust collection accessories. The power of a general vacuum cleaner is 400-1000W or higher, and the power of a portable vacuum cleaner is generally 250W or less. The vacuum cleaner can remove dust mainly because its "head" is equipped with an electric exhaust fan. There is a wind impeller on the shaft of the exhaust fan. After power on, the exhaust fan will generate high suction and pressure at a speed of 500 cycles per second. The air in the fan is replenished in a timely manner, resulting in an instantaneous vacuum inside the vacuum cleaner, forming a negative pressure differ...
