Bucket-wheel excavator is a huge vehicle made for surface mining by using a large wheel. There are two ways how to regulate the speed and the torque of this wheel – the mechanical and the electronic. The purpose of this paper is to analyse both conceptions of the regulation and to devise and implement simulation models of the wheel drive with these two conceptions. For this task we use the electronic regulation model which was already implemented. We finally compare dynamic characteristics and a power consumption of the implemented models.
