An interface apparatus for releasably attaching a primary part of a linear motor to a carriage includes an attachment module configured to attach the primary part of the linear motor to the interface apparatus. At least one insertion portion is configured to permit insertion into a holding portion of the carriage along an axial direction of the linear motor. At least one blocking apparatus is configured to releasably block the at least one insertion portion in the holding portion of the carriage.

A magnetic track system for a transport device for moving a rotor along the magnetic track system includes a plurality of linear sections having an even number of magnets of alternating polarity, which are disposed on a support in each case, the magnetic orientation of the magnets reversing itself at regular intervals across abutting sections n the linear regions of the magnetic track system. In the curved regions of the magnetic track system, on the other hand, the polarity of two adjacent magnets of different sections is the same.

In a method for generating a PWM-signal to drive the power transistors of a half-bridge of a converter with the aid of a digital circuit, a digital reference value is compared to the counter content of a digital counting ramp, and a logic state of the PWM-signal is dependent upon whether the reference value is greater than the counter content of the counting ramp. In this context, at least two counters count counter contents of the counting ramp following one another in alternation, and the logic state of the PWM-signal is dependent upon whether the reference value is greater than the counter contents of counting ramps of each of the at least two counters.
