Description
Technical Field

Background
An Electric machine (also known as "motor") refers to an electromagnetic device that converts or transmits Electric energy according to the law of electromagnetic induction.
Brushless dc motors employ semiconductor switching devices to effect electronic commutation, i.e., electronic switching devices replace conventional contact commutators and brushes. The device has the advantages of high reliability, no reversing spark, low mechanical noise and the like, and is widely applied to high-grade recording seats, video recorders, electronic instruments and automatic office equipment.
The brushless DC motor consists of permanent magnet rotor, multi-pole winding stator, position sensor, etc. The position sensor commutates the current of the stator winding along a certain sequence according to the change of the rotor position (namely, the position of the rotor magnetic pole relative to the stator winding is detected, a position sensing signal is generated at the determined position, the position sensing signal is processed by the signal conversion circuit to control the power switch circuit, and the winding current is switched according to a certain logic relation). The operating voltage for the stator windings is provided by an electronic switching circuit controlled by the position sensor output.
The position sensor is of three types, namely a magnetic-sensing type, a photoelectric type and an electromagnetic type. A brushless DC motor using a magnetic position sensor, in which a magnetic sensor device (e.g., a Hall element, a magnetodiode, a magnetoresistor, or an ASIC) is mounted on a stator assembly to detect a change in a magnetic field generated when a permanent magnet and a rotor rotate.
A brushless DC motor using photoelectric position sensor has a photoelectric sensor on stator, a light shielding plate on rotor, and light source (LED or small bulb). When the rotor rotates, the photosensitive element on the stator intermittently generates pulse signals according to a certain frequency due to the action of the light shielding plate.
A brushless dc motor using an electromagnetic position sensor is a brushless dc motor in which an electromagnetic sensor element (e.g., a coupling transformer, a proximity switch, an LC resonant circuit, etc.) is mounted on a stator assembly, and when the position of a permanent magnet rotor changes, the electromagnetic effect causes the electromagnetic sensor to generate a high-frequency modulation signal (whose amplitude changes with the rotor position).
The silicon steel sheet of the existing dust-absorbing blower motor is generally split, and the installation efficiency is low.
