I Description This machine is used for testing AC asynchronous motors, with automatic, full testing function, fast testing speed, and all data can be tested one time. Testing range: DC resistance, locked rotor current, locked rotor loss, no-load current, no-load loss, power factor, voltage test with working frequency, inter-turn test, three-phase resistance and three-phase current balance, power grid frequency, etc. Suitable motors: Single three-phase fractional horsepower motor, micro-motor, small and medium-sized motor, household appliance motor, power tool, explosion-proof motor and pump motor and so on. Voltage: 0-700V, Current: 200A, Frequency: 45-65HZ. II Main technical data
