In the modern world the economy of industrial resources has got the greatest value. To save on energy is possible only by construction of the electrical machines, that best of all satisfy the requirements for them by these systems.

The constantly growing use of a municipal motor-vehicle transport has led to the necessity of development of the machines which are not pollute air pools by exhaust gases, have low noise level and progressive constructive decisions. Modern technical systems have a number of lacks in the technical and economic parameters due to forces of friction [1]. The new concept of motor-wheel drive excludes many mechanical losses between the engine and the working unit, in which the electric motor and the mechanical transfer are connected [2].

The main area of a motor-wheel’s application is motor industry. Such kind of these devices is used in electric cars, bicycles, invalid carriages, moon rovers. Hence the development of trolley buses with independent power supplies is worthwhile today.

As the engine of motor-wheel’s drive the variant of the contactless synchronous electric machine with a ring coil on the stator and permanent magnets on the rotor was chosen and designed. It provides wider functionality in the heaviest conditions and operating modes in comparison with asynchronous machine [3]. For the majority of control systems the contactless engine is designed as the high-torque low-speed electrical machine.

The magnetoelectric engine is capable to work also in a mode of the generator of electric energy. The design of the stator of the electrical machine allows to simplify the winding and to protect it from various influences. Owing to the very small front parts of a ring winding, the electric engine has the best power and mass-overall characteristics.
