Electric motor influences its surroundings by stray magnetic fields. This influence does matter in certain cases hence reduction of the field intensity outside the motor is a part of the motor design. The primary objective is to provide a safety region for humans, reduce a low-frequency electromagnetic emission, or produce magnetically silent electrical machines for propulsion of some military or...
Modelling of thermal processes in four-wire insulated (XLPE) cables at asymmetric load is considered. The model is based on the connection between the electric energy losses from the conductor temperature, the heat exchange between the phases, and load conditions. Methods uses based on the finite element method of chain-field approach to the construction of mathematical models describing the thermal...
The main purpose of this paper is replacement of an existing DC motor by an optimized Switched Reluctance Motor (SRM) for an automotive application, especially for a first Slovak electric car. The SRM was optimized on the base a new optimization procedure, where input parameters were based on requirements for this vehicle e.g. maximum torque, acceleration and power at different speeds. The optimized...
