1 Engineering and Technical Teaching Equipment Motor-Generator Group AEL-EGMG24 Electrical Machines EMT7C EMT6B INTRODUCTION Synchronous machines can use permanent magnets to provide the magnetic field and since no power is used in providing the field this means that the machines are simpler and more efficient. However, the drawback is that there is no simple way to control such machines. Permanent magnet synchronous generators (PMSGs) are typically used in gensets and applications such as wind turbines.

2 GENERAL DESCRIPTION The AEL-EGMG24 Motor-Generator Group has been designed by Edibon in order to study the behavior of permanent magnet alternator with main motor control. Thanks to this trainer, the student will be able to train the permanent magnet synchronous generator, wire the generator-motor group, analyze the power factor, observe the relationship between speed and voltage, study the behavior without load and check the drop voltage when the user connects resistive, inductive and capacitive loads. The AEL-EGMG24 includes the following modules: N-ALI02. Main Power Supply. N-VVCA/M. AC Motor Speed Controller (intermediate option). EMT7C. Asynchronous Three-Phase Motor of Squirrel Cage (8 poles). EMT6B. Permanent Magnets Synchronous Three-Phase Generator (24VAC). N-TRA30. Three-Phase Isolating Transformer 24VAC/380VAC. N-REFT Ohms Three-Phase Fixed Resistor Module. (2 units) N-INDT. Three-Phase Variable Inductive Load with commutator. N-CONT. Three-Phase Variable Capacitor Load with commutator. N-EAL. Network Analyzer Unit. Optional learning software: In addition, Edibon provides optional software (AEL-EGMG24/ICAI) to reinforce knowledge about this field. This software is formed by: ECM-SOF. EDIBON Classroom Manager (Instructor Software). ESL-SOF. EDIBON Student Labsoft (Student Software).
