Description
Technical field
The utility model relates to a kind of rotor, especially a kind of motor rotor construction with skewed slot.
Background technology
Rotor is the key components and parts in motor, and its material, inner circle size, excircle dimension, flute profile size, slot fit, skew slot angle etc. have direct impact to the electromagnetic noise of motor.And using maximum straight slot motor rotor to realize in long-term use procedure in the market also there is the defects such as electromagnetic noise is large, starting current is large, torque is little, the loss of electric machine is large in it.Due to original traditional design consider comprehensive, Process ba-sis is poor, and auxiliary component, process program are bad to be done, and use inconvenient operation, often goes wrong, as electromagnetic noise problem.Its rotor adopts rotor straight trough, well can not improve the starting performance of motor, and electromagnetic noise is bigger than normal, and has obvious cacophony, easily produces noise circumstance and pollutes.
Chinese Patent Application No. is a kind of threephase asynchronous skewed rotor structure of 201310504511.2, discloses the technical characteristic of " rotor block being provided with some rotor chutes ", but does not make restriction to the structure of skewed slot slotted eye itself.
Utility model content
The purpose of this utility model is the defect in order to solve in prior art existing for motor rotor construction, provides a kind of motor rotor construction with skewed slot.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of motor rotor construction with skewed slot, comprise rotor body and be located in the rotor core on rotor body, described rotor body is provided with multiple winding slot extended along rotor body length direction, and the winding slot notch on described rotor body surface is obliquely installed.
Above-mentioned a kind of motor rotor construction with skewed slot, the cross section of the slotted eye of described winding slot is
type, slotted eye is by the first hole wall of bottom, and the second hole wall and the 3rd hole wall that are positioned at the first hole wall both sides surround, and the junction of the junction of the first hole wall and the second hole wall, the second hole wall and the 3rd hole wall is equipped with arc angling.
Above-mentioned a kind of motor rotor construction with skewed slot, is provided with dividing plate between slotted eye adjacent on described rotor body.
Above-mentioned a kind of motor rotor construction with skewed slot, the thickness of described dividing plate is the twice of the bore of winding slot notch.
Above-mentioned a kind of motor rotor construction with skewed slot, the mouth wall of described winding slot notch is provided with arc angling.
Above-mentioned a kind of motor rotor construction with skewed slot, described winding slot notch is 6 °-8 ° relative to the angle of inclination of rotor core.
The beneficial effects of the utility model are: on this rotor, the notch of winding slot is skewed slot, effectively can improve the starting performance of motor, and increase torque, and reduce electromagnetic noise, the mechanical loss of motor also decreases, and can not produce noise circumstance and pollute; And the junction of the hole wall of the slotted eye of winding slot is all with arc angling, add the smoothness of slotted eye, reduce the damage to coiling, dividing plate is provided with between adjacent slotted eye, the thickness of dividing plate is the twice of the bore of winding slot notch, dividing plate enhances the intensity of winding slot, reduces the interference of electric current between adjacent winding slot and electromagnetism, ensure that the stable output of electric current, torque.
Accompanying drawing explanation
