Abstract

The invention discloses a brushless AC smoke ventilator motor. The brushless AC smoke ventilator motor comprises a rotor, a stator, a casing and a control circuit, wherein the rotor comprises a rotor core, a rotating shaft arranged in the middle of the rotor core, a magnetic steel tightly clinging to the outer ring of the rotor core, and a plastic cage arranged at the outer ring of the magnetic steel, the stator comprises a stator core and an insulation plastic sleeve, each tooth of the stator core is wound with an enamelled wire, the casing comprises a plastic packaging body and an end cover, the control circuit comprises a power source conversion module, and a signal control module and a PWM AC driving module which are connected with the power source conversion module, and an output end of the PWM AC driving module is connected with the enamelled wires. The brushless AC smoke ventilator motor employs an AC power source to directly drive an operation motor, further has properties of stable start and operation, low noise, small vibration, simple and firm structure, high efficiency and energy-saving performance, makes efficiency reaching 75-82%, has energy-saving efficiency 64-67% higher than that of a single phase AC capacitance operation motor.

Description

technical field [0001] The invention relates to a brushless AC range hood motor and belongs to the technical field of motors. Background technique [0002] According to the current single-phase AC capacitor running motor for range hoods, this product has low efficiency (40-45%) and high power consumption. The country compulsorily implements the national standard GB29539-2013 on the energy efficiency limit of range hoods. The improvement of the energy efficiency standard for range hoods raises the energy efficiency level from five to level two. Energy-saving performance indicators are implemented as mandatory standards for products. Range hoods that do not meet energy Production and marketing are permitted. Therefore, at present, many range hoods use brushless DC motors to improve energy efficiency, but the biggest problem with brushless DC motors is the high manufacturing cost, and the price factor prevents the market from being popularized and applied in large quantities. ...
