An electric motor controller equipped with a controller section for controlling a plurality of inverters provided corresponding to each of a plurality of alternating-current electric motors, wherein processing segments of each arithmetic section within the controller section are effectively partitioned to reduce size, mass and cost. A controller section (10) for controlling a plurality of inverters comprises a first common arithmetic section (20) and a second common arithmetic section (30) which provide computed output of a control signal common to each inverter section, individual arithmetic sections (40A, 40B) which separately provide computed output of a control signal for each inverter section, and a common logic operation section (60) which provides a gate signal output for switching control of each inverter section in accordance with signals from the first common arithmetic section (20), the second common arithmetic section (30) and the individual arithmetic sections (40A, 40B). |
