The design of the traction electric drive for electric cars "Formula Student Electric"
The paper is concerned to possible designs of car traction electric drives according to the regulations «Formula Student Electric». A racing car is to have high dynamic properties, and that can be achieved in a variety of ways. Thus, the advantages and disadvantages of the following designs are analysed: a central motor plus a reducer plus a mechanical cross-axle differential; two onboard motors (one for each driving wheel); electric motor-wheels (with sub-variants with two and four motor-wheels). The following results are presented: the examples of using of different designs are given, the design scheme with the central motor is examined, with the electric motor-wheel design to preserve high dynamic electric properties being proposed. However, there are some difficulties that may occur when implementing the proposed scheme. They are also revealed
