Description
Technical field
The utility model relates to a kind of motor, especially a kind of 2 pole three phase asynchronous motors.
Background technology
As everyone knows, every groove conductor number of threephase asynchronous stator is a very important parameter, and it directly has influence on motor performance index, for example: efficient, power factor, locked-rotor torque, locked rotor current, breakdown torque etc.Usually have this situation, find by designing and calculating: the every groove conductor of the stator number of motor integrated performance index preferably the time is decimal or is odd number or approaches odd number.At this moment, technological means commonly used is to increase winding way in parallel, can make every groove conductor number become integer by decimal like this or near integer, or makes every groove conductor number become even number by odd number, perhaps gives up the two layer winding form and replaces with single layer winding.
Usually, adopt the advantage of two layer winding to be: form that can be by the winding short distance to be eliminating or to slacken the high order harmonic component in the motor-field, thereby reduces the noise and the vibration of motor.For example: for number of stator slots is 18 2 utmost point motors, and it is whole, and often adopting winding pitch is 7 or 8 apart from be the 18/2=9 groove, and promptly the short distance ratio is 7/9 or 8/9, influences 5,7 the most serious subharmonic in the motor gas-gap magnetic field in order to weaken; In like manner, be 30 2 utmost point motors for number of stator slots, it is whole, and often adopting winding pitch is 12 or 13 apart from being the 30/2=15 groove, promptly the short distance ratio is 12/15 or 13/15; For number of stator slots is 42 2 utmost point motors, and it is whole, and often adopting winding pitch is 15,16,17 or 18 apart from being the 42/2=21 groove, and promptly the short distance ratio is 15/21,16/21,17/21 or 18/21.
For 2 pole three phase asynchronous motors, the stator winding pattern of middle-size and small-size threephase asynchronous generally has: individual layer chain type, individual layer are with one heart, individual layer intersects, double-deck lap wound; When every extremely every phase groove is counted odd number and adopted single layer winding, then the coil number in 2 parallel branches can not equate, can not realize the balance of 2 parallel branches, will produce circulation between motor when operation two branch roads, cause that current of electric increases, heating in winding is serious, shorten electrical machinery life until burning.When every extremely every phase groove is counted odd number and when adopting double-deck lap wound, though then the coil number in 2 parallel branches equates that conductor number and conductor phase angle in the coil there are differences the balance that can not realize 2 parallel branches.
It is the every groove equivalence of stator winding conductor number divided by the number of stator slot that conductor in all grooves of stator is counted sum.The conductor number of setting in a certain groove of sub-winding is an even number, and then the conductor number is that the conductor number in the stator slot of odd number is that conductor number in the stator slot of even number adds 1 or subtract 1 for the conductor number; If the conductor number is that the interior conductor number of the stator slot of even number is " idol ", if the conductor number is that the interior conductor number of the stator slot of odd number is " very ", then " very "=" idol "+1 or " very "=" idol "-1, the basic conductor number of the every groove of stator winding is " very "+" idol ".
