Motor test bench UHV-316

dynamometerresistanceperformance

Product Introduction:

• This bench is designed for automated factory electrical testing of three-phase asynchronous motors (squirrel-cage and wound-rotor) and DC motors. It verifies product compliance with control and quality standards by running standardized electrical tests and automated test sequences. The system is intended for high-throughput end-of-line, incoming inspection and production-line quality control.
