ELECTRIC MOTORS AND METHODS OF CONTROLLING THEREOF

Electric motors and methods of controlling electric motors are described herein. The electric motors include a mobile component having at least one permanent magnet coupled thereto and a stator spaced apart from the mobile component. The stator includes at least one stator pole having a ferromagnetic core and a coil wrapped around the ferromagnetic core. The ferromagnetic core is naturally attracted to the at least one permanent magnet. The motors also include a magnetic position control system configured to monitor a position of the at least one permanent magnet relative to the stator and controllably deliver an electric pulse to the coil of each stator pole to generate a repulsive magnetic flux on the ferromagnetic core to cancel an attraction force between the ferromagnetic core and the at least one permanent magnet to control movement of the mobile component. En el presente documento se describen motores eléctricos y métodos para controlar motores eléctricos. Los motores eléctricos incluyen un componente móvil que tiene acoplado por lo menos un imán permanente y un estator separado del componente móvil. El estator incluye por lo menos un polo del estator que tiene un núcleo ferromagnético y una bobina envuelta alrededor del núcleo ferromagnético. El núcleo ferromagnético es naturalmente atraído por el por lo menos un imán permanente.
