BEARINGLESS ROTATING ELECTRIC MACHINE WITH FIELD WEAKENING
WARF: P230035US01
Inventors: Eric Severson, Bharat Ramadas
The Invention
UW researchers have discovered that a bearingless permanent magnet motors can be designed to operate in the field-weakening regime. They have found that the airgap length and permanent magnet thickness can be designed within specific parameters to prevent field-weakening from degrading the machine’s force capability. Motors using these geometries, combined with field-weakening methods, enable near complete elimination/significant reduction of torque winding field impact on force creation.
