TID1 Inverter For Three-Phase Asynchronous Motor Vocational Training Equipment Electronic Drives For AC/DC Motors
Mod.TID1 has been designed and carried out to enable deep theoretical/ experimental study on V/Hz scalar servomechanisms for three-phase asynchronous motors with sinusoidal PWM control. TRAINING PROGRAM: • Asynchronous three-phase motor: electrical andmechanical characteristics; • Equivalent circuits; • Structure of the scalar V/Hz bidirectional servomechanism; • Application range; • Analysis of the IGBT three-phase inverter; • Sine three-phase PWM modulation; • Voltage wave-forms on the motor phases; • Current wave-forms on the motor phases; • Variation of the control frequency; • Set-point/frequency/speed ratio; • Acceleration/deceleration ramp; • Dynamic response of the system; • Analysis and use of the supervision software from PC inoperations of speed setting / reading; • Speed/current graph plotting; • Troubleshooting experiences in the servomechanism. TECHNICAL SPECIFICATIONS: • EDUBOX mounting structure; • Silk screen printed diagram with the different circuitblocks of the system; • Measurement test-points; • 2 bar-graph indicators for speed and current; • External control panel with switches and rotarypotentiometer; • Non-destructive fault simulator: possibility of insertion of 8faults at max with the same number of switches.
