Today’s high-speed PM motors employ the latest technology in high strength rare earth magnetic materials to achieve high power density and efficiency. Then a rotor made of high energy magnetic material rotates within that field. A stator coil, powered by an alternating current, creates an electric field. Calnetix’s PM motors’ robust rotor construction provides operations at higher speeds with larger turbo wheels, and their associated power electronics are less costly and simpler to use.
The sensorless control is also very popular for high performance PM motor control. This has been made possible with the advent of high-performance permanent magnets with high energy density and high operating temperature, providing the permanent magnet (PM) motor with industry leading power density and efficiency. High-speed permanent magnet machines possess many desirable attributes that make them attractive for direct drive applications in various industries.
