  • Electric motor with axially movable rotor assembly
    Patent number: 8536750
    Abstract: A mechanical structure (16) for enabling a rotor (28) in a permanent magnet electric motor A to be moved axially relative to a stator (14) under an actuating force, without experiencing frictional sliding during such a movement. As the rotor (28) is moved away from the stator (14), the motor magnetic field is weakened, enabling the motor A to operate efficiently at elevated speeds, extending speed coverage under constant power.
    Type: Grant
    Filed: July 24, 2007
    Date of Patent: September 17, 2013
    Assignee: The Timken Company
    Inventors: Xiaolan Ai, Richard Knepper, Don Remboski, Chris Van Dress, Brad Mularcik
