Abstract: An electromagnetic propulsion system includes a plurality of primary windings and a permanent magnet arranged to move with respect to the plurality of primary windings. A secondary winding of the system is disposed in a non-moving relationship with the permanent magnet. An excitation energy is applied to the plurality of primary windings for creating a magnetic field that includes a base component and low frequency harmonic components. The base component substantially contributes toward motion between the plurality of primary windings and the permanent magnet and the low frequency harmonic components substantially contributes toward generating an electro-motive force in the secondary winding based on displacement between the plurality of primary windings and the permanent magnet.

Abstract: An elevator system includes an elevator car disposed in and arranged to move along a hoistway. A linear propulsion system of the elevator system is constructed and arranged to propel the elevator car, and includes a plurality of primary coils engaged to and distributed along the hoistway generally defined by a stationary structure. A wireless power transfer system of the elevator system is configured to inductively transfer power to the elevator car. The wireless power transfer system includes a secondary coil mounted to the elevator car and is configured to be induced with electromotive forces by the primary coils and output power for use by the elevator car. A communication system of the elevator system is configured to utilize the secondary coil and the plurality of primary coils to exchange a communication data signal.

Abstract: An elevator system may include an elevator car having an electrically powered car subsystem and a guide rail constructed and arranged to guide the elevator car along a hoistway and in a direction of travel. Primary windings of the system are positioned along the hoistway, and a permanent magnet assembly is coupled to the elevator car. Together, the primary windings and the permanent magnet assembly define a linear motor for imparting motion to the elevator car in response to a drive signal. A secondary winding assembly of the elevator system is coupled to the elevator car and is located adjacent to the permanent magnet assembly along the direction of travel. In operation, the secondary winding assembly generates a current to power the car subsystem.
