Electrical Drives for Autonomous Ecological Vehicles

In the paper two specific examples of electrical drives for autonomous ecological vehicles are presented. The first one is a realization of the electrical drive propulsion of a boat for tourist purposes. A DC electrical drive with a chopper-based speed control system and a mechanical gearbox is chosen taking into consideration purpose of the boat and design solutions. Accumulator batteries are employed for power supply. A drive wheel with paddles ("Mississippi" system) is used rather than a propeller to make the boat more attractive for tourists. The second example presents a solution of an additional electrical drive for a bicycle. A drive involving permanent magnet synchronous motor connected to a drive wheel by cog-wheels and chains system is described. Characteristics of the motor as well as a transistor-converter as power part of this electrical drive are described. Presented solutions of electrical drives for autonomous vehicles have shown good ecological properties so they can be related as "autonomous ecological vehicles".
