MACHINE ELECTRIC DRIVE CONTROL DEVICE Russian patent published in 2004 - IPC

FIELD: electrical engineering; controlling drives of miscellaneous machines.

SUBSTANCE: novelty is that control device that can be used for various machines such as pick-and-place ones where driving cab is disposed at certain distance from motors of actuating elements is provided with newly introduced connector and that decoder is connected to relay unit to form interface unit coupled through connector to coder units. Control units with control elements and control modules with control components are integrated by control consoles to form electrical machine control board. Decoder unit has control component position sensors arranged in tandem and provided with permanent magnet incorporating U-shaped permeable clamp. With neutral position of working element permanent magnet is disposed above central sensor and butt-ends of U-shaped clamps, above sensors mounted either side of central sensor.

EFFECT: enlarged functional capabilities, enhanced reliability and service life.
