Technical Field

[0001] The utility model relates to the field of full-contact voltage and current wiring terminals of permanent magnet motors, in particular to a full-contact detection tool for voltage and current wiring terminals of permanent magnet motors. Background Art

[0002] AC permanent magnet synchronous motors have been widely recognized in various industries in today's society due to their small size, light weight, high efficiency and energy saving. As the operating characteristics of the motors and their control technology become increasingly mature, they have attracted more and more attention. Practice in recent years has shown that in order to reduce size, save materials, improve efficiency and reduce energy consumption, more and more asynchronous motors are being gradually replaced by permanent magnet motors.

[0003] However, when testing the current, resistance, voltage and insulation of the permanent magnet motor's stator, there are many copper wire terminals on the motor. If the inspection is done manually, it will not only increase the workload of the inspectors, but also reduce the inspection efficiency. Secondly, when inspecting the motor stator, it is necessary to turn on the power for inspection, so the inspectors need to pay attention to the safety of electricity use at all times. When the inspectors are always performing one inspection, it is easy to cause mental fatigue, which may lead to safety accidents. In order to solve the above problems, we have proposed a full-contact inspection tool for the voltage and current terminals of the permanent magnet motor. Summary of the Invention

[0013] Compared with the prior art, the utility model has the following beneficial effects: the permanent magnet motor voltage and current terminal full-contact detection tooling, through the output end of the first cylinder will drive the connecting block to move upward, and then prompt the placement base to drive the motor stator to move upward, so that multiple detection terminals are in contact with multiple copper wire terminals at the upper end of the motor stator.
