An electric motor controller equipped with a controller section for contr olling a plurality of inverters provided corresponding to each of a pluralit y of alternating-current electric motors, wherein processing segments of eac h arithmetic section within the controller section are effectively partition ed to reduce size, mass and cost. A controller section (10) for controlling a plurality of inverters comprises a first common arithmetic section (20) an d a second common arithmetic section (30) which provide computed output of a control signal common to each inverter section, individual arithmetic secti ons (40A, 40B) which separately provide computed output of a control signal for each inverter section, and a common logic operation section (60) which p rovides a gate signal output for switching control of each inverter section in accordance with signals from the first common arithmetic section (20), th e second common arithmetic section (30) and the individual arithmetic sectio ns (40A, 40B). |
