Groschopp is presenting a new
electrically excited synchronous motor that is part of a scalable axle drive module for electric vehicles. The axle drive module should be ready by mid-2015 and, thanks to its scalability, will be suitable for various electric vehicles. Six medium-sized industrial companies and four research institutes are participating in the development, which is called 'ESKAM'. Groschopp's sub-project involves the development and design of a high-speed electrically excited electronically commutated synchronous motor (EEEK). In contrast to the 'permanently excited electronically commutated synchronous machine PMEK' used to date, this type of motor does not require permanent magnets. In addition, the magnetic field can be regulated by the excitation current, allowing the machine to be adapted to the required load point. An output power of 2 x 25 kW at a speed of 20,000 min-1 is the target for a demonstrator.
