Document Type and Number:
Japanese Patent JP2001502761
Kind Code:
A
Abstract:
A drive system (10) for driving an inertial mass (40) over a drive path between first and second extreme positions comprises an electrical drive motor (12, 14), linkage means (30) connecting the drive motor (12, 14) to the mass (40) for driving the mass, a storage capacitance (20) for storing electrical power, and a control system (16, 18) for applying electrical power to the drive motor (12, 14) to accelerate the mass (40) over a first portion of its drive path from one of the first and second extreme positions. The control means (16, 18) connects the drive motor (12, 14) to the storage capacitance (20) such that when the drive motor acts as an electromagnetic brake during deceleration of the mass (40) over a second portion of its drive path towards the other of the first and second extreme positions electrical power generated by the drive motor (12, 14) is used to charge the storage means (20). A monitoring device (22) monitors the level of energy stored in the storage means (20) and the control means applies power from the storage means (20) to the drive motor (12, 14) during acceleration of the mass (40) over the first portion of the drive path when the electrical power stored in the storage means (20) exceeds a preset level.
