Description
Set of Modular Electric Machines
This set of modular machines is proposed as ”first approach” in a Laboratory of Electric Machines; it has been designed to assembly and test a large number of electrical machine (motors and generators) using few base components. In fact, with this set it is possible to study:
- the components of each type of machine,
- the mechanical assembly of these components,
- the electric connections of these components,
- the power supply of the various windings; and
- applying the measurement instruments to detect the most important parameters
Trainin Program
- This set enables to expound the following training program on the machines of the table included in this leaflet:
- Measurement of the resistance of windings and correction for temperature
- Mechanical assembly of the various machines of the list with the proper care for alignments and the respect of the air gap
- Electrical connections of the machines of the list. In detail, as regards DC machines, the connections with separate, shunt, series, additive compound and subtractive compound excitation will be examined
- Influence of the position of brushes on DC motors
- For all the motors, when the brake is provided, detection of electromechanical characteristics: Torque, RPM and efficiency of motors
- Detection and measurement of the characteristics of DC generators and calculation of the output power
- The same for the three-phase alternators, with R-L-C load. Measurement of power factor. The “Prime Mover” unit is recommended to drive the generators
