AAC-1 Modular Educational Systems For Drives Of AC Motors Teaching Equipment Electrical Workbench

System mod. AAC-1 has been designed and manufactured with industrial components according to educational standards. It is the suitable tool for the theoretical-practical study of AC motor drive.
TECHNICAL CHARACTERISTICS:
Trainer mod. AAC-1 consists of three units for the exhaustive study of the industrial drive of an AC motor. These units are:
A1A AC DRIVE - Microprocessor module
A2A AC MOTOR CONTROL - Power circuit
MDAQ - Data acquisition module
The development of the exercises of the training program consists in fixing the units in the support mod. TSI-1, placing over the due overlay for the exercise under test and arranging the proper connections.
Each unit includes a panel of insulating material with Ø = 4 mm safety terminals, for connections.
Connecting module MDAQ will supply the (opto-isolated) signals of voltages and currents of unit A2A.

A1A AC DRIVE – Microprocessor module
Module A1A is connected with module A2A via a 25-pole connector and enables its operation by generating the necessary signals for control of power circuits.
It includes a 4-line alphanumeric display to show various data, such as the codes of the module and of the connected overlay, the set point value, the selected control mode (open or closed loop, with tachogenerator or armature voltage) etc... This Module includes a PID controller for the speed of the AC motor coupled to a tachogenerator (motor & tachogenerator are not included), connected with unit A2A.
It is possible to set the P, I and D values and the acceleration & deceleration ramps. The on-board pushbuttons enable the navigation through the menu, and the potentiometers allow to modify the selected parameters. Furthermore two other analog inputs of 0 to 10 V are available for the connection with any source of external signals.
A2A AC MOTOR CONTROL – Power circuit
Unit A2A includes the power circuits for the AC motor.
It consists of a VSI-type three-phase inverter whose control signals come from unit A1A. This three-phase inverter includes 6 IFBT transistors. The maximum power of motors that can be connected is of approximately 1000 W. A “Chopper”-type braking circuit is available and two Ø = 4 mm safety terminals enasble to control motor overtemperature. The DC power supply for the inverter comes from a Graetz bridge with capacitor fi lter. Three Ø = 4 mm safety terminals available on the panel enable to connect this unit with the three-phase motor. Other two specifi c Ø = 4 mm safety terminals allow the connection with a tachogenerator for closed loop control. Connecting module MDAQ with 15-pole connectors will supply the (opto-isolated) signals of voltages and currents available in the circuit.
MDAQ - Data acquisition module
Module MDAQ supplies the (opto-isolated) signals of the unit which it is connected with, on 30 safety terminals (Ø = 2 mm).
The opto-isolated signals ensure electrical safe conditions for students when carrying out measurements: for instance, it is not necessary to use differential probes when using oscilloscope.
