Title:
ELECTRIC MOTOR
Document Type and Number:
WIPO Patent Application WO2003055042
Kind Code:
A8
Abstract:
The invention relates to an electric motor, in particular for high speed operation, comprising a motor housing (4); inside the housing (4), a stator (2) having a core (8) and windings (9) toroidally wound on the core (8); and a rotor (1) inside the stator (2). The motor comprises an inductance controlling ring (3) in soft-magnetic material around the stator core (8), increasing for each phase the leakage inductance and forming for each phase an integrated filter inducatnce (L1, L2, L3) outside the core (8) of the stator (2) but still inside the motor housing (4).
