Abstract
An electric drive system in lift trucks has, for driving the lift truck driving wheels, at least one separate excitation electric motor provided with a stator and a rotor which are energized independently of each other by means of an electronic drive and control unit; by this arrangement, space can be saved on the lift truck and the lift truck can be rendered reliable, low in running cost, adaptable to varying load conditions, and adjustable as regards its operational parameters.
