Technical field
The present invention relates to field of motor manufacturing more particularly to a kind of three phase alternating current motor integer slot stator lead-out wire phase sequence to examine
Survey device.
Background technique
It is that end line is coupled to U, V, W after stator coil embedding that three phase alternating current motor integer slot stator, which draws wiring,
Lead-out wire and from left to right or from right to left ordered arrangement.For small in size, structure is very compact, and U, V, W lead-out wire are shorter
Motor after dipping lacquer, assembly when test run, such as finds that phase sequence is not right, cannot exchange lead-out wire in the position of terminal box.It can only cut
Fall bandage and reforms lead-out wire.Due to dipping lacquer, do over again more difficult.
Summary of the invention
It is an object of the invention to overcome disadvantages described above, three intersections that can be detected lead-out wire phase sequence before a kind of dipping lacquer are provided
Galvanic electricity machine integer slot 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 slot stator lead-out wire phase sequence

Unit, the motor stator and three phase alternating current motor to be detected of the three phase alternating current motor integer slot stator lead-out wire of the correct phase sequence
The requirement of integer slot stator design is identical, and the quantity N of the detection unit is three phase alternating current motor integer slot stator to be detected
Stator core slot number is divided by number of pole-pairs, and Hall element, current-limiting resistance, light emitting diode form a magnetic pole detection unit, just
Both threads are taken to be subject to direct current between motor stator lead-out wire U, V of the three phase alternating current motor integer slot stator lead-out wire of true phase sequence
Stream, lead-out wire U connect anode, and lead-out wire V connects cathode, by the three-phase of the first detection unit alignment correct phase sequence of N number of detection unit
The teeth portion of the first slot of motor stator iron core wire embedding side of alternating current generator integer slot stator lead-out wire, remaining detection unit successively connect
The motor stator core teeth portion of the continuous three phase alternating current motor integer slot stator lead-out wire for being placed in correct phase sequence, detection unit connect phase
Matched DC power supply records the lumination of light emitting diode situation of N number of detection unit respectively, and three phase alternating current motor to be detected is whole
Number slot stators according to the same position of three phase alternating current motor integer slot stator of correct phase sequence two lead-out wires respectively with power supply
Positive and negative anodes are connected, and N number of detection unit is successively continuously placed in three phase alternating current motor integer slot stator core teeth portion to be detected, works as hair
Optical diode luminous situation is identical as the LED lighting situation of three phase alternating current motor integer slot stator of the correct phase sequence of record
When, then the motor is qualified, otherwise unqualified.
Preferably, N number of detection unit is mounted on the same printed circuit board, and the detection unit is mounted on printing
After on circuit board, the distance of neighbouring detecting elements matches with three phase alternating current motor integer slot stator core tooth pitch to be detected.
The testing principle of the present apparatus is, when Hall element front is by the pole the N magnetic line of force, output end is in high level, hair
Optical diode shines.When Hall element front is penetrated by the pole the S magnetic line of force, output end is low level, and light emitting diode is not
