Abstract
A floor cleaning apparatus driven by a switched reluctance drive that is soft-started to substantially avoid any transient torque reaction disturbing the body of the cleaner. The soft-start is produced by profiling the current demand for the drive system as a function of the rotor speed. Profiling is typically done with a continuous function, a series of steps or a pair of values. Related methods provide similar advantages.
