The invention discloses a piece of micro motor rotor test equipment and a micro motor rotor test method. The test equipment comprises a test bench equipped with a slide rail, a drive device arranged on the test bench, and two brush moving devices arranged at the two ends of the slide rail in a sliding manner. A limit board is arranged between the two brush moving devices. Each brush moving device is equipped with a brush at the end. The drive device comprises a drive motor, a base bearing which is arranged in an accommodating hole, and an adapter seat of which the lower end sleeves the base bearing. The upper end of the adapter seat extends and exposes the test bench. The adapter seat is provided with a center shaft hole which runs through the upper end and the lower end. A motor shaft is arranged at the lower end of the center shaft hole. A rotor shaft is arranged at the upper end of the center shaft hole. The upper end of the adapter seat is equipped with a magnetic steel ring which is arranged concentric with a hollow cup coil. Through the device and the method, a micro motor rotor can be tested easily, and the test efficiency is improved. The device and the method have the advantages of simple structure and reliable work.
Description
technical field [0001] The invention relates to a testing device, in particular to a testing device for a rotor of a micro-motor. Background technique [0002] The rotor is one of the three important parts of the micro-motor, mainly composed of a coreless coil and a commutator. The last process of making the rotor is the rotor test, which mainly tests the resistance value between the pole pieces on the top of all commutators to judge the state of the coils of each section and avoid performance defects after the rotor is installed. [0003] The existing rotor test is to manually hold the rotor with one hand, and the other hand holds the two test leads of the multimeter to touch the pole pieces of the commutator, and observe the resistance indication while rotating the rotor to detect whether the rotor is qualified. The main disadvantages are: 1. It is inconvenient to operate the hand-held product test, and it is easy to pinch the hollow cup coil; 2. The pole piece on the top...
