Disassembly and Assembly of an Induction motor
Instructors Introduction:
Disassembly and Assembly of A.C. Motors
What we will be working on today is the disassembly and assembly of an A.C. Three Phase Squirrel Cage Motor. You will be using the Lab-Volt Trainer Model no 8020. The Model 8020 Dissectible Machines is an electromechanical (EMS) trainer that provides hands-on instruction in the construction and operation of rotating machines. The system fulfills educational requirements that include industrial applications of electric power technology. It employs training equipment that has characteristics similar to industrial equipment.
The dissectible machines are assembled without the use of tools from a complete set of components, including stators, rotors, and armatures. Once assembled the motors can be mounted on basic modules that lock into place on one of Lab-Volts EMS workstations. The components allow the students to construct two different machines at the same time; fifteen different machines can be constructed with these components.
Motor windings are connected to the faceplate of the module with polarized plugs, allowing for the correct interconnection of motors. Schematic connections are silkscreened on the interchangeable plastic face on the basic module. Once assembled and plugged into the EMS workstation, motors can be coupled together to demonstrate electrical and mechanical characteristic.
Laboratory procedures in the correlated courseware guide students through each assembly and disassembly of the three phase squirrel cage motor. Each component is identified, and a complete assembly drawing is supplies with each motor.
A mobile work bench with a component storage area and a work surface for motor assembly are included in the system. An extra partially wound stator, a set of windings, and a set of loose laminations are included with the system to assist in the teaching of basic winding techniques.
Features of this Lab-Volt (EMS) test set is that it comes complete with assembly drawings for each motor, no tools are required for motor assembly, two motors can be assembled at the same time and once the motors are assembled they can be used to demonstrate their electrical and mechanical characteristics.

We will now watch a short video on the assembly and disassembly of an induction motor. The following video shows the basics of motor assembly. As motors in general are built along the same lines there are very little differences between how the parts are put together. The basic design is fundamentally the same for all three phase motors and the differences lie in the addition of one or more extra components mounted on the shaft and the number of wiring connections made to the motor.
