Abstract
The utility model discloses a high-power outer rotor ultra-low speed permanent magnet brushless direct current motor, which comprises a front end cover and a rear end cover that are respectively arranged at two ends of a housing, and a stator and a rotor which are arranged in the housing, wherein the stator comprises a main shaft and a stator core provided with a winding and arranged on the main shaft, and the rotor comprises a housing and a steel magnet arranged on the inner wall of the housing. The peak power of the motor can reach 2000 KW, and the rotational speed is from several circles to hundreds of circles per minute; the motor has the characteristics of high efficiency, large torque, high starting torque, high power factor, energy conservation, environmental protection and the like, and can be widely used on any occasions requiring ultra-low rotation, such as the oil industry, the textile industry and so on; and the motor can exert the superior development when applied to the military field.
Description
Technical field
The utility model relates to a kind of motor, particularly a kind of high-power external rotor Ultra-Low Speed brushless, permanently excited direct current motor.
Background technology
Owing to technical reason, for high-power external rotor Ultra-Low Speed brshless DC motor, domestic manufacturer does not also grasp design and making ability at present, can't meet the needs of production, the device particularly big for the ask for something moment of inertia, that starting torque is big, common electric machine can't meet the demands especially.
The utility model content
The purpose of this utility model is the deficiency that exists at prior art, provides a kind of high efficiency that has, high pulling torque, high starting torque, the high-power external rotor Ultra-Low Speed brushless, permanently excited direct current motor of High Power Factor and energy-saving and environmental protection characteristics.
The technical solution of the utility model is: a kind of high-power external rotor Ultra-Low Speed brushless, permanently excited direct current motor, comprise front end housing and the rear end cap that is arranged on the casing two ends and be arranged on casing interior stator and rotor, it is characterized in that: described stator includes main shaft and is arranged on the main shaft and has the stator core of winding, and described rotor includes casing and is arranged on magnet steel on the casing inner wall.
The utility model compared with prior art has the following advantages:
The peak power of the high-power external rotor permanent magnet brushless DC motor of the utility model can reach 2000kW, and rotating speed changes from several hundreds ofs that go to of per minute; Motor has characteristics such as high efficiency, high pulling torque, high starting torque, High Power Factor and energy-conserving and environment-protective, can be widely used in any occasion that needs the Ultra-Low Speed rotation; Motor uses the brshless DC motor nonshared control unit to carry out drive controlling, can be operated in the workplace that needs the frequent rotating of motor, can make the motor rotating or have different speed or realize anxious stopping by control system, be the ideal product that is used for equipment such as tower-type pumping unit, drilling well winch.
