Abstract

Providing control apparatus with a maximum torque/current ratio control means by which the relationship between the maximum torque and current amplitudes and the relationship between the maximum torque and current phases are converted to numeric expressions including one or more than one linear function with the torque taken as the parameter, then the current amplitude command and current phase command data that yields a maximum torque is computed, and computed data is sent as an output signal.
