TRANSFORMERS AND MOTORS KITS

The proposed kits consist of a set of components commonly used in the electro mechanics construction and a laboratory exercise handbook.
The components sizes, quality and hardness have been chosen so as to make easy the assembling work for the students and to guarantee at the same time an immediate understanding of the theoretical principles which lay the basis of the electric machines design. The handbook delivered with the kits illustrates comprehensively the construction principles and is an effective guide to the design of the motors and of the transformers.
