Educational Kit for Electrical Machine Winding and Assembly
The Motor Winding Kit is designed to help students understand and master the manufacturing techniques used in rotating electrical machines. It provides a hands-on approach to motor and synchronous machine construction using basic components such as magnetic laminations, shafts, mechanical parts and insulated copper magnet wire.
Electrical Machines That Can Be Constructed
The kit includes two types of stator laminations for constructing single-phase or three-phase windings. Three rotor configurations are also provided:
- A squirrel-cage rotor for constructing a three-phase induction motor.
- A rotor made of open-slot laminations, allowing students to wind a three-phase wound rotor.
- A rotor made of cruciform laminations and a damper assembly, enabling the construction of a four-pole synchronous machine rotor.
The rotors are built around a double-ended stainless-steel shaft, onto which the ball bearings and laminations are permanently assembled. Students can therefore manufacture and assemble several electrical machine configurations by following the instructional procedures provided.
Winding Equipment and Accessories
The kit includes a manual coil winder fitted with an adjustable mandrel and a turn counter, facilitating the production of windings according to the technical specifications provided in the manual. All necessary materials are supplied, including insulated magnet wire, slot liners, insulating materials, wooden wedges and lacing cord.
The essential tools required for winding and assembly operations are also included: a plastic mallet, scissors, wire stripper, soldering iron and compass. The supplied materials are sufficient to wind each type of machine at least five times.
Machine Assembly and Operation
Once the stators and rotors have been wound, students follow detailed procedures for mechanical and electrical assembly. The assembled machines can be mounted on a dedicated support module using clamps and wing nuts. Machine windings are connected to the corresponding module terminals through a polarized connector.
Each machine is provided with an interchangeable cover displaying its rated specifications and winding diagrams. Electrical components such as capacitors, centrifugal switches and potentiometers can be attached to the machine or its base using dedicated tool-free fastening systems.
The assembled machines can subsequently be integrated into a compatible EMS training workstation and operated like conventional preassembled electrical machines. This configuration enables students to perform practical experiments and investigate the operating characteristics of different machine types. The workstation and the equipment required to operate the assembled rotating machines are available as optional accessories.
After each experiment, the windings can be removed from the slots, allowing the stator and rotor laminations to be reused for further winding exercises.
