12, 1930. [Class 38 (iii).] A synchronous motor 10 is started as an induction motor under excess voltage supplied by a compensator 11, switches 15, 20 being closed. Thereafter field switch 29 is closed, switch 20 is opened, leaving the motor under supply with part of the compensator ...
The Permanent Magnet Synchronous Motor back EMF methods of estimation is based on the motor of the mathematical model, a general based on the motor stator two coordinate system of the model equations, the back EMF and motor speed and position of the relationship, and get speed and position.5...
The control under sampling of synchronous motors in a (α-β) representation is considered as a case study. This allows us to underline some pathology due to the discretization and reduction of this kind of nonlinear systems关键词: digital control discrete time systems machine control nonlinear ...
ac Motor Control and Protection: Starting, Running Protection, and Surge Protection Starting methods for ac motors range across a broad spectrum from across-the-line starting to various types of reduced voltage starters; more recently, electronically controlled starting is being used. When rated voltag...
