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: electrical and 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 in operations of speed setting / reading and speed/current graph plotting;
