Abstract
The utility model discloses a double-wheel-shaped external rotor electric motor, belonging to the technical field of an electric motor and comprising an electric motor shaft, an internal stator and an external rotor. The utility model is characterized in that belt wheels and two end covers of the electric motor external rotor are fixed into an entirety and are supported on the electric motor shaft through two bearings. The double-wheel-shaped external rotor electric motor is provided with two belt wheels which are respectively arranged at the outer sides of two end covers of the external rotor of the electric motor; and the diameter of the two belt wheels can be smaller than that of the external rotor of the electric motor and can be also bigger than that of the external rotor of the electric motor. The two belt wheels and the two end covers of the electric motor can be respectively processed and then fixed as an entirety with screws and can be also entirely processed. The utility model can meet the requirements of different conveying rates and conveying force, and simultaneously, the anti-load-carrying capacity of the motor is greatly enhanced and the electric motor is more suitable for the condition of heavy duty.
Description
Technical field
The utility model relates to a kind of external-rotor motor with two drives, belongs to the motor technology field.
Technical background
Number of patent application is 03242883.9 external-rotor-type torque motor oil pumper, and its technical scheme has been simplified the structure of oil pumper to greatest extent, has reduced the energy delivery loss, has innovation thinking preferably.But in the technical scheme of motor part, remain in weak point, the external rotor that mainly is motor directly is processed into pulley shape and the double belt wheel of doing, this diameter that just certainly will define belt wheel must be identical with the diameter of motor outer rotor, the size of the transfer rate of its belt wheel and conveying capacity was also just determined thereupon after the power of motor, rotating speed were determined, made a kind of motor of parameter can only be suitable for a kind of special operating conditions.Simultaneously,, increase rolled steel dosage because the double belt wheel of doing of external rotor under the condition of this especially big gravity load of oil pumper, certainly will will increase considerably the thickness of outer rotor case, also unreasonable on mechanical structure.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, the outer rotor motor that provides a kind of same motor to be suitable for multiple different operating requirement and to have high load capacity.
The purpose of this utility model is achieved through the following technical solutions: a kind of two-wheel shape outer rotor motor, form by motor shaft, internal stator and external rotor, the two end cap that it is characterized in that belt wheel and motor outer rotor is fixing as a whole, is supported on the motor shaft through two bearings.Described a kind of two-wheel shape outer rotor motor has two belt wheels, and two belt wheels place the outside of motor outer rotor two end cap respectively; The diameter of two belt wheels can be less than the diameter of motor outer rotor, also can be greater than the diameter of motor outer rotor; The two end cap of two belt wheels and motor outer rotor can be processed respectively then and with screw the two is fixed into an integral body, also can monoblock cast process.
Advantage of the present utility model is: the motor of same parameter can adapt to the requirement of different transfer rates and conveying capacity by the size of adjusting pulley diameters, simultaneously owing to adopt the double pulley structure, the anti-load-bearing capacity of motor is greatly improved, be more suitable for working under the heavy load conditions.
Description of drawings
Accompanying drawing is the structural representation of the utility model two-wheel shape outer rotor motor.
Comprise among the figure: rotor overcoat 1, end cap 2, belt wheel 3, bearing 4, motor reel 5, support 6, outer iron core 7, coil 8, interior iron core 9.
Embodiment
Two-wheel shape outer rotor motor described in the utility model can be a permanent-magnetic electric machine, also can be switching magnetic-resistance formula motor, and this specific embodiment is a switching magnetic-resistance formula motor.Below in conjunction with specific embodiment design feature of the present utility model is described further:
A kind of two-wheel shape outer rotor motor, accompanying drawing can be used as the structural representation of a kind of specific embodiment of the present utility model.The stator of motor by motor reel 5, be fixed on the support 6 on the motor shaft, iron core 7 and the coil 8 that is fixed on the support periphery constitutes; The rotor of motor by rotor overcoat 1, be fixed on the rotor core 9 of Side in the rotor overcoat, the two end cap 2 that links with the rotor overcoat and two belt wheels 3 that are fixed together with end cap respectively constitute.The two end cap of two belt wheels and motor outer rotor can be processed respectively then and with screw the two is fixed into an integral body, also can monoblock cast process, and this specific embodiment is that monoblock cast processes.Electric rotor is supported on the motor shaft by two bearings.
Two belt wheels of above-mentioned motor and two end cap are fixing as a whole, and the diameter of belt wheel can be less than also can be greater than the diameter of motor external rotor, the diameter of this specific embodiment belt wheel is less than the diameter of motor external rotor, and it is applicable to the occasion that requires low transmission speed, big conveying capacity.
When the utility model two-wheel shape outer rotor motor used, two external parts of motor reel were fixed on the unsplit frame, rotated for preventing motor reel, and two extensions are fit to do into many prismatics.
Claims (3)
1, a kind of two-wheel shape outer rotor motor is made up of motor shaft, internal stator and external rotor, it is characterized in that the two end cap of belt wheel and motor outer rotor is fixing as a whole, is supported on the motor shaft through two bearings.
