<P>PROBLEM TO BE SOLVED: To provide a motor controller by which a large-sized motor or the like can be driven by driving and controlling a plurality of inverter devices with one motor drive command from the motor controller. <P>SOLUTION: One motor drive command (a torque command) S is output from the motor controller 1. Coefficients A1-A4 preset to the motor drive command S are multiplied and the motor drive commands S×A1-S× A1 to each inverter device are calculated at a relay device 3. The motor drive commands S×A1-S× A1 are input to each inverter device IV1-IV4 respectively. By this, one motor 2 is driven. The motor 2 is driven by the sum total of currents supplied from each inverter device IV1-IV4. Consequently, large torque can be generated. Only a processing part for generating and processing one motor drive command S is required in the motor controller 1. The motor drive command to the other motor can be generated and output. Thus, the other motor can be driven. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
