Abstract

Method for adjusting i.e. matching the speeds in r.p.m. of several asynchronous motors that drives, in particular, a mining machine, as in P23 03250, and where each drive unit is associated with a hydrostatic governor. In addition, the asynchronous motors of each drive unit are now connected in non-positive drive, via a superpositioning gear, by means of which one outgoing shaft is connected to the operating machine and another outgoing shaft is connected to a hydrostatic governor. An equal load sharing is given even when the asynchronous motors have different characteristics. The intermediate shafts and governors protect the motors against sudden loading from the operating machine.
