Description Générale

The DC Electrical Motors Applications, "AEL-DCEMT", has been designed by EDIBON to carry out electrical/mechanical tests for a great variety of DC motors. Such tests allow obtaining the most significant electrical and mechanical characteristics of these motors .In addition, it is advisable to acquire the Control and Data Acquisition System Software for Electrical Machines, ‘’EM-SCADA’’, with which the user will be able to obtain the characteristic curves for the tested electric motors and fulfill reports and comparisons of the obtained curves for each electric motor to study its advantages and application fields.

The "AEL-DCEMT" allows the user to learn in depth the behavior of a great range of DC motors, such as DC Independent excitation Motor, DC Series excitation Motor, DC Shunt excitation Motor- Generator, DC Compound excitation Motor-Generator, etc.

For this purpose, the application includes a servomotor, an overcurrent relay and a series of measurement devices, such as an analog ammeter , an analog voltmeter, a multimeter and an optical speed meter. All these included elements are essential to study the AC motors characteristics. Dynamic braking tests can be carried out through the servomotor while parameters such as speed, electrical current, the voltage, the power factor or the active and reactive powers are measured.

For the fulfillment of electric motors advanced tests, it is advisable to acquire the Control and Data Acquisition System Software for Electrical Machines, ‘’EM-SCADA’’. This advanced software allows monitoring the waveforms for current, voltage, torque and speed to study in depth the electric machines.
