A kind of intelligent integrated controls food waste disposer brshless DC motorTechnical field
The invention belongs to motor technology field, be specially a kind of intelligent integrated and control food waste disposer brshless DC motor.
Background technology
Current normal food garbage disposer motor employing series excited machine, have large, the inefficient deficiency of noise, and the series excited machine life-span depends on carbon brush, the life-span of carbon brush only has 1000 hours, thus causes the useful life of series excited machine short.
Summary of the invention
The object of the invention is to overcome food waste disposer motor employing series excited machine in prior art, there is large, the inefficient deficiency of noise, and the series excited machine life-span depend on carbon brush, the life-span of carbon brush only has 1000 hours, thus the deficiency causing the useful life of series excited machine short, a kind of intelligent integrated is provided to control food waste disposer brshless DC motor, this motor adopts plastic package structure and advanced type of drive, effective raising electric efficiency, reduction motor noise, improve electrical machinery life.
Technical scheme of the present invention is achieved in that a kind of intelligent integrated controls food waste disposer brshless DC motor, it comprises rotor assembly, plastic packaging body, end cap, wire, sensing baseplate and external drive plate, described plastic packaging body is formed by high-temperature molding in a mold by stator module and thermosetting capsulation material, ensure that the consistency of air gap between plastic packaging body and rotor assembly, the sensing baseplate of described electric machine built-in three transducers, the three phase mains terminal of described motor plastic package body stator module is wired on external drive plate.
As preferably, described motor drive plate uses FOC to be with position transducer, the corner observer based on model reconstruction, the sinusoidal wave 180 ° of control technologys of SVPWM.This drive plate improves electric efficiency, reduces noise.
Compared with prior art, plastic packaging body of the present invention is formed by high-temperature molding in a mold by stator module and thermosetting capsulation material, this process structure can ensure the consistency of air gap between plastic packaging body and rotor assembly, effectively improves electric efficiency, reduces noise; The sensing baseplate of electric machine built-in three transducers, effectively improves rotor fixed position precision and electric motor starting speed, improves electric efficiency, reduces noise; The three phase mains terminal of motor plastic package body stator module is wired on external drive plate, motor drive plate uses FOC to be with position transducer, the corner observer based on model reconstruction, the sinusoidal wave 180 ° of control technologys of SVPWM, improve electric efficiency, reduce noise, this DC brushless motor life-span depends on bearing grease, the bearing grease life-span can reach more than 20000 hours, substantially prolongs the DC brushless motor life-span.

Embodiment
The specific embodiment of the present invention is as follows:
Embodiment: as shown in Figure 1, 2, a kind of intelligent integrated controls food waste disposer brshless DC motor, it comprises rotor assembly 1, plastic packaging body 2, end cap 3, wire 4, sensing baseplate and external drive plate 5, described plastic packaging body is formed by high-temperature molding in a mold by stator module and thermosetting capsulation material, ensure that the consistency of air gap between plastic packaging body and rotor assembly, the sensing baseplate 7 of described electric machine built-in three transducers, the three phase mains terminal of described motor plastic package body stator module is wired on external drive plate.Described motor drive plate uses FOC to be with position transducer, the corner observer based on model reconstruction, the sinusoidal wave 180 ° of control technologys of SVPWM.This drive plate improves electric efficiency, reduces noise.
The plastic packaging body that above-mentioned intelligent integrated controls food waste disposer brshless DC motor is formed by high-temperature molding in a mold by stator module and thermosetting capsulation material, this process structure can ensure the consistency of air gap between plastic packaging body and rotor assembly, effectively improves electric efficiency, reduces noise; The sensing baseplate of electric machine built-in three transducers, effectively improves rotor fixed position precision and electric motor starting speed, improves electric efficiency, reduces noise; The three phase mains terminal of motor plastic package body stator module is wired on external drive plate, motor drive plate uses FOC to be with position transducer, the corner observer based on model reconstruction, the sinusoidal wave 180 ° of control technologys of SVPWM, improve electric efficiency, reduce noise, this DC brushless motor life-span depends on bearing grease, the bearing grease life-span can reach more than 20000 hours, substantially prolongs the DC brushless motor life-span.
Finally, it should be pointed out that above embodiment is only the more representational example of the present invention.Obviously, technical scheme of the present invention is not limited to above-described embodiment, can also have many distortion.All distortion that those of ordinary skill in the art can directly derive from content disclosed by the invention or associate, all should think protection scope of the present invention.
