The utility model is characterized in that an intermediate partition plate is arranged between the disk type stator and the disk type rotor, one side of the disk type rotor is provided with an output shaft, and the stator is provided with a cooling device. The utility model has the advantages of good sealing performance and no dielectric leakage; the utility model can be started at full capacity, and is suitable for being used in the fields of petroleum chemical industry, military industry, food, pharmacy, etc.; the utility model can be used as a shield pump of electromechanical integration.
Description
The utility model relates to a kind of motor, especially a kind of no shaft seal disc-type electric motor.
China utility model patent specification ZL95232715.5 is disclosed to be a kind of disc-type electric motor, does not have spacer between the stator and rotor of this motor, and stator and rotor are contained on the output shaft by bearing.When motor is worked, because electromagnetic induction, be positioned at stator center output shaft one end axle surface and be easy to generate vortex phenomenon, make the heat of output shaft and stator coil generation distribute and does not go out, cause the too high and scaling loss of machine operation temperature easily; In addition, because the stator of motor and rotor bulk cargo on output shaft, during motor work, cause dielectric leakage easily.ZL97244365.7 utility model patent specification, disclosed is a kind of disc-type electric motor that cage is installed between stator and rotor.But, this motor will stator and rotor adorn by bearing, on output shaft, cage can not guarantee fully that medium does not leak, and processing, installs all cumbersomely, exists heat equally and looses and do not go out the too high problem of motor temperature.Because prior art exists above-mentioned defective, makes promoting the use of of disc-type electric motor be subjected to certain limitation.
The purpose of this utility model is to provide a kind of disc-type electric motor that does not have dielectric leakage, can reduce working temperature.
The utility model above-mentioned purpose realizes by following technological means.
A kind of disc-type electric motor, the disc type stator core upper edge of placing in housing is circumferentially uniform, radially radiation has the three-phase slot for winding, coil rolls off the production line by folded formula and places in the slot for winding, in the end cap made from magnetic material that disk rotor is contained in housing is connected, be oppositely arranged with stator, it is characterized in that: be provided with the intermediate isolating plate between disc type stator and disk rotor, output shaft is equipped with at disk rotor one side center, and this output shaft is by the bearing holder (housing, cover) and the bearing fixing thereof that are packed on the end cap.Utilize above-mentioned intermediate isolating plate, disc type stator and disk rotor are packed in two isolated chambers relatively independently.The said structure design has solved in the prior art, and the motor stator of existence and rotor bulk cargo cause the dielectric leakage problem easily on output shaft.Simultaneously, be provided with cooling device, and the coolant that is processed with the connection cooling device on housing helps reducing the motor working temperature into and out of the hole in the centre of said stator.Above-mentioned cooling device can adopt liquid nitrogen cooling device, also can adopt the coiled cooling device.
The utility model is owing to set up the intermediate isolating plate between stator and rotor, and obstructed Axile connection structure can guarantee that fully medium does not have leakage.The place is provided with cooling device in stator center, can make the temperature of motor be unlikely too high.So, the utility model good leak tightness, no dielectric leakage can start at full capacity, is suitable for fields such as oil, chemical industry, military project, food, pharmacy, as the canned pump use of electromechanical integration.
Introduce the utility model specific embodiment in detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation.
Fig. 2 is the A-A profile of Fig. 1.
By Fig. 1 and Fig. 2 as can be seen, disc type stator core 8 is loaded in the housing 3, circumferentially uniform in stator core 8 upper edges, radially radiation has the three-phase slot for winding, coil 7 rolls off the production line by folded formula and places in the slot for winding, coil 7 and the stator core 8 common stators of forming, the disk rotor made from magnetic material 4 is arranged in the end cap 1, and is connected with output shaft 6, intermediate isolating plate 2 separates stator and rotor 4 fully, makes medium not have leakage.Division board 2 links together with end cap 1 and housing 3, and coiled cooling device 5 is installed in the cavity of stator center position, and the coolant that is processed with the connection cooling device on the housing 3 is used for stator is cooled off into and out of the hole.
