AEL-EMSS | ELECTRICAL MACHINES SOFT STARTERS APPLICATION

Description

This application includes an eddy current brake to study the induction motor response to different load conditions.

On the other hand, for more advanced studies of induction motor dynamics, it is recommended to acquire the “N-SERV1K” servomotor, which includes a controller to perform different braking tests with greater precision. This controller can work together with the “EM-SCADA” module.

When the braking torque is increased, the power consumption of the induction motor is increased too, the power factor changes, etc. In order to analyze the power consumption of the induction motor a network analyzer is included. It shows the main electrical parameters which are relevant in industrial installations: voltages, currents, frequencies, Power Factor, active power, reactive power, apparent power, etc.

This application can be supplied with the Control and Data Acquisition System Software for Electrical Machines, “EM-SCADA”, a Data Control and Acquisition Software developed by SOHAIL CORPORATIONS that allows monitoring all voltage, current and torque waves shape. This allows studying the behavior of the three-phase induction motor via different soft starters offered in this application. The servomotor can be controlled from the PC with EM-SCADA to generate different load curves on the induction motor shaft. In this way it is possible to graphically obtain the characteristic curves of this type of motor.
