test system
MTS-IV-1032 asynchronous motor test system
Composition--
Dynamometer (hysteresis, magnetic powder, eddy current, electric power)
KZQ-III dynamometer controller.
DPM3001 three-channel digital power meter/DPM1001 single-channel digital power meter
Computer
AC regulated power supply
Temperature inspection instrument
micro resistance meter
Measured parameters--
Voltage, current, input power, torque, speed, output power, efficiency, power factor, frequency, motor winding resistance, ambient temperature, winding temperature, stator temperature, bearing temperature, etc.
Function--
The test parameters are automatically collected by computer, and the functions are modularized. After each function test is completed, the relevant curve is generated, and the test report can be printed out. After all function tests are completed, the total test report is generated.
Test basis standard--
GB1032-2012 Test Methods for Three-phase Asynchronous Motors
GB 9651-Test Methods for Single-phase Asynchronous Motors
Test accuracy--
Accuracy: 0.2 percent
Main test items--
Cold and hot DC resistance test
Temperature rise test: the resistance temperature measurement method is used to calculate the motor temperature rise, and the temperature inspection instrument can also monitor the motor winding temperature, iron core temperature, etc.
No-load test: measure the no-load characteristic curve and calculate the no-load current, no-load power, iron consumption and mechanical consumption.
Stall-rotor test: measure the locked-rotor characteristic curve and calculate the locked-rotor torque and current.
Load test: measure the modified load characteristic curve and calculate the modified motor parameters
T-N curve drawing: the asynchronous motor real-time T-N curve drawing, and automatically find the maximum torque and minimum torque and single-phase asynchronous motor centrifugal switch disconnect point speed.
Applicable occasions--
Single, three-phase asynchronous motor, synchronous motor, variable frequency motor
