Electromechanical linear drive for line scanner, with compensation of moments resulting from high accelerations, includes compensation control unit for controlling second actuator in synchronous anti-phase motion with first actuator

摘要

The electromechanical moment compensation drive (13, 21, 31, 33) includes a second actuator (13) with second path of motion parallel to the first. It is supported by a third return spring assembly (31, 33) against a third abutment (37) rigidly connected to the first abutment and biased to the resting position. A second load (21) is rigidly connected to the second actuator (13) and is driven by it. A compensation control unit is provided. This controls the second actuator (13) in synchronous antiphase motion with the first (11).
