1results about How to "Real-time test" patented technology

This utility model provides a technical field of testing devices, disclosing an overspeed testing device for commutators, including a frame with a platform on its top surface; a laser displacement sensor section mounted on the platform, comprising a laser displacement sensor for detecting inter-segment errors and circular runout errors of the commutator; a high-speed electric spindle section mounted on the platform for mounting the commutator and providing it with overspeed rotation; and an industrial hot air blower section with its outlet pointing towards the commutator to provide a heat source. The device tests and monitors inter-segment errors and circular runout errors of the commutator in real time under high-temperature and high-speed rotation conditions, providing experimental basis for commutator manufacturers to improve commutator materials and processes.
