Description
Technical field
The utility model is related to a kind of squirrel-cage copper rotor motors, belong to mechanical equipment technical field.
Background technology
Squirrel-cage motor, squirrel-cage threephase asynchronous (Squirrel-cage motor) refer to determining for motor
Embedded Distributed Winding is dissipated for three-phase on son, rotor is the conducting bar of cage.Motor, can shape after stator winding adds three-phase alternating current
Into rotating excitation field, the conducting bar of the closure on rotor can be because electromagnetic induction generates potential and electric current, and the conductor charged is in magnetic
Movement will be generated in.Motor rotor just rotates.Here it is the operation principles of squirrel-cage threephase asynchronous.
In use, often there is problems in existing squirrel cage motor：(1), conducting bar uses aluminium conducting bar, and loss is higher, temperature
Raising is used for a long time conducting bar and needs to be replaced frequently, and the service life of motor is shorter；(2), conducting bar is often under the influence of centrifugal force
It throws away, the stator of rotor exterior can be scratched, conducting bar is not thrown out of in order to prevent, also has user to consider with glue or without tying up
It is fixed but all impracticable.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of squirrel-cage copper rotor motor, can carry
The service life of high motor reduces loss, while can prevent conducting bar from throwing away.
The purpose of this utility model is achieved through the following technical solutions：A kind of squirrel-cage copper rotor motor, including
Stator and rotor, the rotor include rotor core and rotating cylinder, and rotor core is formed by multilayer silicon steel plate stacking, and described turns
Sub- iron core is detachably connected integrally by multiple iron core units, and each iron core unit is formed by 10-15 piece silicon steel plate stackings, rotor
More are provided on iron core relative to the inclined conducting bar hole of machine shaft axis direction, conducting bar hole from rotor core center to its two
The shape of side is wedge shaped, the red copper conducting bar and the red copper end ring group at red copper conducting bar both ends that rotating cylinder is mounted on by more in conducting bar hole
Into.
The conducting bar hole tilts 15-25 ° relative to machine shaft axis direction.
The thickness of the silicon steel sheet is 0.35-0.55mm.
Location hole is provided in the iron core unit, is linked into an integrated entity between iron core unit by positioning screw.
The red copper conducting bar is in be used with the matched wedge shape in conducting bar hole, red copper conducting bar with conducting bar hole from center to both sides
It is full of cooperation.
The beneficial effects of the utility model are：Using red copper conducting bar, the characteristics of due to red copper, red copper conducting bar electric conductivity than
Aluminium conducting bar it is high by more than 40%, red copper conducting bar can be remarkably decreased the total losses of motor, so as to improve the whole efficiency of motor,
While the loss of electric machine reduces, since the energy for being converted into thermal energy is reduced, so that rotor and stator coil temperature drop
Low, the reduction of operating temperature substantially prolongs the service life of motor and reduces maintenance cost；Meanwhile to two centered on red copper conducting bar
Side is wedge shaped, will not be thrown away during high speed rotation, and has the characteristics that simple in structure, easy to use.
