Title:
MOTOR CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/003807
Kind Code:
A1
Abstract:
In a multiphase motor, no matter which phase there is phase interruption for, the phase of the current is adjusted appropriately. A controller 203 controls the driving of a motor 100. The motor 100 has a plurality of armature windings 121a, 121b, 121c corresponding respectively to a U phase, V phase, and a W phase, and each armature winding is connected independently from each other. When there is phase interruption to any phase of the U phase, the V phase, and the W phase, with any of the normal phases excluding the phase for which there was phase interruption as a reference phase, the controller 203 adjusts the phase of the current flowing in the normal phase other than the reference phase so as to not extend to the phase for which phase interruption occurred.
