Originální abstrakt

An electric lawn mower supplied from batteries was designed and constructed. Li-ion cells are used because of their high volumetric and weight energy density. Falling prices of these batteries allow such a conception to be practical. Two separate motors are used – one for the traction and the other for the main blade drive. Both motors are brushless DC motors (three-phase synchronous motors with permanent magnets with a specific waveform of the induced voltage). Hall sensors are used to sense the rotor position which is necessary for the control of converters. A high torque outrunner construction of the blade motor was selected to eliminate the need of a gearbox. The used battery capacity of 1.6 kWh was shown to be unnecessarily high for a practical operation – a long operation time (more than 3 hours for one charge), high weight.
