Sistema di prova motori MTS-IV

Composition

Dinamometro (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 power supply

Temperature inspection instrument

Micro-resistance meter

Measurable parameters

Voltage, attuale, potenza in ingresso, coppia, velocità, potenza in uscita, efficienza, fattore di potenza, frequenza, resistenza dell'avvolgimento del motore, temperatura ambiente, temperatura dell'avvolgimento, temperatura dello statore, temperatura del cuscinetto, ecc.

Function

The test parameters are automatically collected by the 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 the function tests are completed, the total test report is generated.

Test basis standard

GB1032-2012 “Three-phase asynchronous motor test method”
GB 9651 “Single-phase asynchronous motor test method”

Test Accuracy

Accuracy: 0.2%

Main Test Items

Cold and hot DC resistance test
Temperature rise test: The temperature rise of the motor is calculated by the resistance temperature measurement method, and the temperature of the motor winding and the iron core temperature can also be monitored by the temperature inspection instrument during the test
No-load test: Measure the no-load characteristic curve, calculate the no-load current, no-load power, iron loss, and mechanical loss
Locked-rotor test: Measure the locked-rotor characteristic curve, calculate the locked-rotor torque and the locked-rotor current
Load test: Measure the modified load characteristic curve and calculate the modified motor parameters
T-N curve drawing: real-time drawing of the T-N curve of the asynchronous motor, and automatically find the maximum torque and minimum torque, and the speed of the centrifugal switch disconnection point of the single-phase asynchronous motor.
