The present invention discloses a novel brushless microwave oven cooling fan motor. The motor comprises a motor base, a porous bearing, a stator assembly, a rotor assembly and a circuit board. The stator assembly comprises a stator core, a wire-mounting clamp, a wire-dismounting clamp and wire packs. The stator core, the wire-mounting clamp and the wire-dismounting clamp are fixedly installed on the central post of the motor base. There are two wire packs which are installed on the stator core around the stator core. The rotor assembly comprises a magnetic steel ring, a plastic magnetic stripe and a rotor spindle. The rotor shaft is connected with the porous bearing of the central post of the motor base. The plastic magnetic stripe and the magnetic steel ring are sleeved on the rotor spindle and are connected with the motor base. The circuit board is fixed on the motor base. The novel brushless microwave oven cooling fan motor is simple and novel in structure and convenient and flexible in usage, can allows the motor to perform direct current power supply and perform alternating current low-voltage power supply through adoption of electronic control components so as to allow the manufacturing cost of the motor to greatly reduce, and greatly improve a series of integrated performances of the motor through adoption of the novel brushless structure. The novel brushless microwave oven cooling fan motor is compact in integrated structure, big in moment of force, small in input power, small in noise and high in efficiency, the maximum output power can reach 5.2W, and the energy saving effect is obvious.
Description
technical field [0001] The invention relates to the field of microwave oven components, in particular to a novel brushless microwave oven cooling fan motor. Background technique [0002] In the prior art, a microwave oven is generally equipped with a transformer, and the transformer is installed below the magnetron at the bottom of the oven cavity. When the microwave oven operates for a period of time, the temperature of the transformer rises rapidly. In order to cool the internal components of microwave ovens, blow away the water vapor generated by food, and dissipate heat from transformers and magnetrons, cooling fan motors are generally installed in microwave ovens. However, the existing cooling fan motors for microwave ovens generally use shaded pole motors, which consume a lot of power. , the noise is loud, and it is not in line with the current energy-saving environment. [0003] In order to overcome the above defects, the present invention makes beneficial improvemen...
