Control Of Motors That Do Not Use Commutators
(AREA)
Abstract
This invention presents a starting method and apparatus for permanent magnet synchronous motor drives. The basic idea is to determine the commutation according to the current of either permanent magnet synchronous motor or DC-link of inverter during starting up. The permanent magnet synchronous motor can speed up to the required speed without any position sensor while limiting the starting current.
