Magnetomechanical drive or torque amplifier with electrodynamic energy recovery

摘要

The drive consists of at least two similar permanent magnetic drive cells with drive pistons (1.1, 1.4) made of a non-magnetic light metal body (1.2) and a permanent magnet (1.3) pref. based on a rare earth. The drive pistons have axial bores for a drive shaft (1.12) and are joined so that no dynamic imbalance forces occur even at high revolution rates. The light metal body in the operating pistons (1.5,1.6) can be connected via suitable non-magnetic bolts to a non-magnetic thrust rod (1.7) which is connected to the crankshaft (1.8) via another bolt. One end of the crankshaft is connected to a flywheel mass (1.9) for dynamic storage of mechanical rotation energy. The pistons, crankshafts and bearings are in a light metal housing (1.10). The pistons, drive shaft and bearings are joined to the housing via the bearing block (1.11). The permanent magnets are arranged with facing magnetic North poles and both parts of each piston are designed for optimum rotation.
