DSD1 Servomechanism For DC-Shunt Motor Educational Equipment Electrical Laboratory Equipment
Mod. DSD1 is the instrument necessary to the high level theoretical-practical study on the subjects concerning the thyristor AC/DC servomechanisms for DC-SHUNT motors. TRAINING PROGRAM: • DC-SHUNT motor with separated excitation: electricaland mechanical characteristics; • Structure of the bidirectional SCR servomechanism; • Application range; • Current and voltage waveforms of the motor; • Speed control with tachogenerator; • Speed control with inner current loop; • PI regulators; • Proportional action-speed controller calibration; • Proportional action-current controller calibration; • Integrative action; • Set-point/ignition angle/SCR/speed ratio; • Acceleration and deceleration ramps; • Synchronism signal; • Signal produced by the modulator; • Dynamic response of the system; • Analysis and use of the supervision software from PC inoperations of speed setting / reading and speed/currentgraph 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.
