MP-D Machines are direct current machines of the multipolar type, i.e. ma chines whose torque is produced in a cylindrical current tube through axiall y oriented current flow in a plurality of turns between pairs of parallel pe rmanent magnet poles attached to cylindrical concentric magnet tubes. Unlike other multipolar type machines, MP-D machines' magnet tubes comprise a plur ality of permanent magnets in the form of continuous circumferential sleeves . The current tube in MP-D machines remains stationary while at least one of the two magnet tubes rotates. MP-D machines may be powered or may generate direct current. |
