Servo Motor Trainer

• The Vectorial field oriented control servomechanism for asynchronous three phase motor mod.FDC/EV enables the student to learn.

• Demonstrate and experiment the main concept of field oriented control, enriching the personal theoretical background with the practical aspects f industrial designed maintenance.

• The power of the servomechanism, the circuit solutions, the used components, make the training program to be developed on a totally industrial product and not on a simulator.

Following demonstrational capabilities would be included with the trainer:

• Asynchronous three-phase motor: electrical and mechanical characteristics

• Vectorial field-oriented control (F.O.C.)

• Speed and torque control

• Analysis of the IGBT three-phase inverter

• “Space vector” vectorial modulation

• Voltage/current wave-forms on the motor phases

• Dynamic response of the system

• Programming the servomechanism via keyboard or PC with dedicated software

• Analysis and use of the data acquisition software from PC.

• Troubleshooting experiences in the servomechanism.
