Abstract

The invention discloses equipment for testing permanent magnetic rotor magnetic steel. The equipment comprises a driving motor, a dial plate, a first lead screw, a second lead screw, a wound core, a dynamic balance tool, a rotor, a photoelectric induction element, a supporting frame and a proximity switch. Hardware equipment is mounted on the dynamic balance tool, the rotor rotates on the dynamicbalance tool, the wound core can generate induced electromotive force, the two ends of a coil of the wound core are connected to an oscilloscope controller, the coil can generate waveforms, and through waveform comparison, whether the rotor is qualified or not is detected. According to a testing method of the rotor magnetic steel, the rotor rotates, the magnetic flow in the wound core changes allthe time, and according to the faraday electromagnetic induction principle, the induced voltage can exist on the coil; and the waveforms of the voltage can change along with change of the magnetic flow change rate, thus by measuring and analyzing the induced voltage and the current waveforms, change of the magnetic flow of the wound core can be directly judged, and then intensity and polarity of amagnetic field of the rotor, designed harmonic wave magnitude and the like can also be judged.

Description

technical field [0001] The invention belongs to the technical field of motor manufacturing, in particular to a device for testing permanent magnet rotor magnetic steel. The invention also relates to a testing method for the rotor magnetic steel. Background technique [0002] As labor costs continue to rise, more and more companies are adopting automated equipment to replace manual work and further reduce human errors and mistakes. At present, the products produced by industrial units are subject to production inspection, delivery inspection, routine, ring screening and other tests before delivery according to the standards. There are many test items and complicated test data records. In the existing motor test, the test of the magnetic steel is a key step to ensure the performance of the motor. [0003] Magnetic steel components are mainly used in permanent magnet motors, which are important components of permanent magnet motors, and their quality directly affects the outp...
