Abstract:
An algorithm for identifying a motor type of a multi-phase (typically 3-phase) motor is described. The algorithm applies a series of active voltage vector pulses to the phases of the motor and measures the current rise-time for each applied voltage vector. The motor type is determined on the basis of the measured current rise-times.
