Abstract
The utility model is related to a kind of magneto eccentric rotor structure, it by：Rotor punching, permanent magnet trough, axle, ventilation slot are constituted.Rotor punching is on axle, and one week difference of rotor punching is uniformly provided with multiple permanent magnet troughs and ventilation slot, and the cylindrical of rotor punching is off-centre operation, and the center of relative axle is eccentric.The product structure is simple, it is reasonable in design, due to being provided with permanent magnet trough and ventilation slot within one week in rotor punching, the cylindrical of rotor punching is off-centre operation, can substantially reduce the torque of rotor teeth groove, eliminate skewed stator slot, welded without punching be superimposed, solve rotor using flume structure can not mosaic magnet the problem of, manufacture craft is simple, man-hour is saved, cost of labor is reduced.
Description
Technical field
The utility model is related to a kind of magneto eccentric rotor structure.
Background technology
Because permanent magnet machine rotor itself has cogging torque, the torque directly affects magneto starting characteristic and torque
Pulsation, reduces the control characteristic and reliability of operation of magneto servo drive system, influences the control accuracy of system, and
Vibration noise etc. can be caused.The mode of more traditional elimination cogging torque is that skewed stator slot is provided with stator, on rotor
Rotor chute, skewed-rotor etc. are provided with, but is not applied to for permanent magnet machine rotor skewed slot, skewed-rotor is operated in technique to be relatively stranded
Difficult, it is impossible to mosaic magnet, skewed stator slot, which needs punching being superimposed, to be welded, and it is long that welding expends man-hour, it is impossible to makes
Use cramp.
The content of the invention
The purpose of this utility model is to overcome disadvantages mentioned above there is provided a kind of magneto eccentric rotor structure, and it is main
The mode for solving traditional elimination cogging torque is that skewed stator slot is provided with stator, and rotor chute is provided with rotor, is turned
Sub tiltedly pole etc., but do not applied to for permanent magnet machine rotor skewed slot, skewed-rotor operates more difficult in technique, it is impossible to inlay permanent magnetism
Body, skewed stator slot, which needs punching being superimposed, to be welded, and it is long that welding expends man-hour, it is impossible to the problems such as using cramp.This
The purpose of utility model be achieved in that magneto eccentric rotor structure by：Rotor punching, permanent magnet trough, axle, ventilation slot
Constitute.Rotor punching is on axle, and one week difference of rotor punching is uniformly provided with multiple permanent magnet troughs and ventilation slot, rotor punching
The cylindrical of piece is off-centre operation, and the center of relative axle is eccentric.The product structure is simple, reasonable in design, due to the one of rotor punching
Week is provided with permanent magnet trough and ventilation slot, and the cylindrical of rotor punching is off-centre operation, can substantially reduce the torque of rotor teeth groove, eliminate
Skewed stator slot, welded without punching is superimposed, and solving rotor can not mosaic magnet using flume structure
Problem, manufacture craft is simple, saves man-hour, reduces cost of labor.
Brief description of the drawings：
Accompanying drawing 1 is the structural representation of the utility model magneto eccentric rotor structure.
1-rotor punching, 2-permanent magnet trough, 3-axle, 4-ventilation slot
Embodiment：Describe most preferred embodiment of the present utility model in detail below in conjunction with the accompanying drawings, magneto is eccentric
Rotor structure by：Rotor punching 1, permanent magnet trough 2, axle 3, ventilation slot 4 are constituted.Rotor punching 1 is mounted on axle 3, rotor punching 1
Multiple permanent magnet troughs 2 and ventilation slot 4 are uniformly provided with one week respectively, and the cylindrical of rotor punching 1 is off-centre operation, in relative axle 3
The heart is eccentric.When manufacturing, the eccentric throw of rotor punching 1 can be determined according to real electrical machinery amount of capacity.
