ABSTRACT:
The motor according to one aspect of the present invention has an output waveform correcting unit for correcting the waveform of the output signal of a magnetic sensor during operation of the electric motor. ID codes for identification purposes are assigned respectively to a plurality of magnetic sensors. The output waveform correcting unit receives, from an external device, output waveform correction values for the magnetic sensors together with the ID codes, and stores the output waveform correction values for the magnetic sensors in memory. The drive system according to another aspect of the present invention has a plurality of electric motors, and a system controller connected to the plurality of motors via a shared communication line. Each electric motor has an identification code register that stores an identification code for identifying each electric motor. The system controller has an individual control mode in which operation of individual motors is controlled by transmitting commands to individual electric motors together with identification codes via the shared communication line.
