ABSTRACT:
A controller for an electric machine, in particular for a linear motor, is disclosed. The electric machine or linear motor includes a first machine section with windings and a second machine section with permanent magnets. The controller includes a memory which can store one or more physical parameters, such as magnetic field parameters, that can be used to control the electric machine. The physical parameter(s) can be determined by having the electric machine perform one or more reference passes.
