MOTOR CONTROL DEVICE Russian patent published in 2011 - IPC H02P5/74 H02P27/08 B60L15/20 

FIELD: electricity.

SUBSTANCE: motor control device having controller to control multiple inverters which are provided for each of multiple ac motors; at that, the size, weight and cost have been reduced by effective grouping of operations performed with each computing unit included in the controller. Controller (10) to control inverters includes the following: first common computing unit (20) and the second common computing unit (30), which compute and output control signals which are common for each of the inverters; individual computing units 40A and 40B, which individually calculate and output the control signal referring to each of the inverters; and common logic computing unit (60) which outputs enabling signal for controlled switching of each of inverters on the base of the signals received from the first common computing unit (20), the second common computing unit (30) and individual computing units 40A and 40B.

EFFECT: decreasing dimensions, weight and cost of motor control device.
