Using inductive transmission devices, sensors and actuators on moveable appliances could be easily supplied with electrical energy without any huge effort. Based on an electromagnetic energy-field, which is transmitted from a primary coil to a secondary coil, a reliable electric power supply can be assured. This dedicated near field transmission offers great advantages also considering harsh industrial environments conditions. Thus, the power transmission will not be deranged, even not by water, dirt, dust or coolant. The Air gap Power Coupling Unit SPS-PCU allows save transmission in an easy way, particular previous knowledge is not required.
Having no parts to wear out or service the system needs no maintenance work. Due to operating in a low frequency range electrical and magnetic emissions (EMI) are not expected.
