Description
Technical field
A kind of the present invention relates to field of motor manufacturing, more particularly to three phase alternating current motor integer groove stator lead-out wire phase sequence inspection
Survey device.
Background technology
It is after stator coil rule that wiring drawn by three phase alternating current motor integer groove stator, and end line is coupled to U, V, W
Lead-out wire from left to right or from right to left ordered arrangement.For small volume, closely, U, V, W lead-out wire is shorter for structure
Motor, after dipping lacquer, assembling during test run, such as finds that phase sequence is not right, can not exchange lead-out wire in the position of terminal box.Can only cut
Fall bandage to reform lead-out wire.Due to dipping lacquer, do over again more difficult.
Content of the invention
It is an object of the invention to overcoming disadvantages described above, there is provided can detect before a kind of dipping lacquer that the three of lead-out wire phase sequence intersects
Stream motor integer groove stator lead-out wire detection device for phase sequence.
The present invention is achieved through the following technical solutions：A kind of three phase alternating current motor integer groove stator lead-out wire phase sequence
Detection means, it include the motor stator of the three phase alternating current motor integer groove stator lead-out wire of a correct phase sequence, magnetic pole detection
Unit, the motor stator and three phase alternating current motor to be detected of the three phase alternating current motor integer groove stator lead-out wire of the correct phase sequence
The requirement of integer groove stator design is identical, and quantity N of the detector unit is three phase alternating current motor integer groove stator to be detected
Divided by number of pole-pairs, Hall element, current-limiting resistance, light emitting diode constitute a magnetic pole detector unit to stator core slot number, just
Both threads in addition direct current is taken between motor stator lead-out wire U, V of the three phase alternating current motor integer groove stator lead-out wire of phase sequence really
Stream, lead-out wire U connect positive pole, and lead-out wire V connects negative pole, the three-phase that the first detector unit of N number of detector unit is aligned correct phase sequence
The teeth portion of motor stator iron core wire embedding the first groove sidepiece of alternating current generator integer groove stator lead-out wire, remaining detector unit connect successively
The motor stator core teeth portion of the continuous three phase alternating current motor integer groove stator lead-out wire for being placed in correct phase sequence, detector unit connect phase
The dc source of coupling, records the lumination of light emitting diode situation of N number of detector unit respectively, will be whole for three phase alternating current motor to be detected
Number groove stators according to the same position of the three phase alternating current motor integer groove stator of correct phase sequence two lead-out wires respectively with power supply
Both positive and negative polarity be connected, N number of detector unit is continuously placed in three phase alternating current motor integer groove stator core teeth portion to be detected successively, when send out
The luminous situation of optical diode is identical with the LED lighting situation of the three phase alternating current motor integer groove stator of the correct phase sequence of record
When, then the motor be qualified, otherwise unqualified.
Preferably, on same printed circuit board, the detector unit is installed in printing for N number of detector unit
After on circuit board, the distance of neighbouring detecting elements is matched with three phase alternating current motor integer groove stator core tooth pitch to be detected.
The Cleaning Principle of this device is, when Hall element front is subject to the N poles magnetic line of force, its output end is sent out in high level
Optical diode lights.When Hall element front is penetrated by the S poles magnetic line of force, its output end is low level, and light emitting diode is not
Luminous.
The method have the benefit that, a dc source need to be connected between two phase sequences only, you can by detection
Three phase alternating current motor integer groove magnetic pole of the stator to be detected is compared with the three phase alternating current motor integer groove magnetic pole of the stator of correct phase sequence
Relatively judging cross streams motor integer groove stator to be measured whether misphase, whole to three phase alternating current motor so as to can achieve before dipping lacquer
The detection of number groove stator lead-out wire phase sequence.
