This work deals with complete designing of electric drive for lightweight motorcycle. There are mentioned options of electric drive and types of batteries. One solution for Jawa 50/555 motorcycle frame is picked. In this work are measured losses of traction motor and cooling system is modified. There are some necessary calculations of drive. In next part 10S6P Li-ion battery with balancer and undercharge controller is realized. In this thesis design of step – down converter with current control is described, cooling and PCB is proposed. Complete converter with cover is made.
Electric drive, brushed DC electric motor, step – down converter, current controller, pulse width modulation. Li-ion battery
