EP1500549A3

Controller for driving a permanent magnet type synchronous motor

Abstract

A motor terminal voltage or IPM input voltage necessary to achieve a target operating point (T*, N) is computed based on torque command (T*) and motor revolution (N). When the computed voltage (V) exceeds an actual battery voltage (VB), a booster is inserted between the battery (12) and IPM (14), and the battery voltage, after being boosted, is applied between the direct current terminals of the IPM (14). Since the motor terminal voltage can be made so as to not exceed the boosted voltage even if the motor terminal voltage rises along with a rise in revolution (N) and speed voltage (ω•E0), field weakening control becomes unnecessary.
