Patent ID: 7958830

Claim:
A linear motor for a modular transportation device, comprising: at least one primary part having a plurality of field-generating coils that are mounted side-by-side along a predetermined route; at least one secondary part, wherein the plurality of field-generating coils of the at least one primary part provides a propulsion field for propulsion of the at least one secondary part, and wherein the at least one secondary part is configured to support at least one consumer positioned on the at least one secondary part; an energy transmitting interface interposed between the at least one primary part and the at least one secondary part; a set-point interface; a coil drive circuit that is stationary with respect to the at least one primary part; and a support unit for providing rigid support of the at least one secondary part, wherein the support unit guides the at least one secondary part along the predetermined route; wherein an energy supply field having a higher frequency than a frequency of the propulsion field is superposed on the propulsion field, wherein the energy supply field is inductively coupled via the energy transmitting interface and supplies energy to at least one AC/DC converter provided on the at least one secondary part, wherein the at least one AC/DC converter is connected to the energy transmitting interface and supplies the at least one consumer positioned on the at least one secondary part, wherein the at least one consumer is connected to the AC/DC converter via a DC/DC converter, wherein the at least one secondary part includes at least a permanent magnet and a signal-processing device having one of a propulsion controller and a motion controller, wherein the one of the propulsion controller and the motion controller generates at least one set-point value relevant to coil control, wherein the at least one set-point value is supplied via the set-point interface from the at least one secondary part to the coil drive circuit as the quantity used for commutation, and wherein the linear motor is configured to be driven in one of a mono-phase and multi-phase manner.
