Linear rolling motor
Abstract
Abstract A LINEAR MOTOR IS DISCLOSED USING STATOR ELECTROMAGNETS SPACED ALONG A LINEAR GUIDEWAY, FOR EXAMPLE, TO GUIDE A VEHICLE FOR RAPID TRANSIT GUIDANCE AND PROPULSION. THE VEHICLE CARRIES AN ARMATURE REACTING WITH THE STATOR ELECTROMAGNETS FOR THE PROPULSION OF THE VEHICLE. THE ARMATURE IS MAGNETICALLY POLARIZED AS BY A PERMANENT MAGNET TO ELIMINATE ANY NEED FOR ELECTRICAL POWER OR CONTROL CONNECTIONS TO THE VEHICLE, FOR EXAMPLE, BY THE USUAL THIRD RAIL OR OVERHEAD CATENARY. THE ARMATURE IS PREFERABLY A ROTATABLE WHEEL RUNNING ON THE GUIDEWAY AND THE STATOR ELECTROMAGETS ARE ENERGIZED IN TRAVELLING SEQUENCE TO REACT WITH THE ARMATURE TO PROPEL THE VEHICLE INDEPENDENT OF ANY TORQUE ON THE WHEEL.
