Motor controller
Abstract:
When the torque command value is zero, a set point of DC current for an inverter is calculated to obtain a difference between the set point and a detected DC current so that an error in magnetic pole position may be estimated and corrected. By correcting the magnetic pole position, unwanted power running and regenerative torque of the motor can be avoided and unnecessary charge or discharge to or from a battery can be prevented.
