Document Type and Number:
WIPO Patent Application WO/2019/138308
Kind Code:
A1
Abstract:
The invention relates to a permanent-magnet synchronous motor or generator comprising at least one rotor (2) and at least one stator (3, 8). The motor comprises two rotors (2), four stators (3, 8) and a cooling system (7, 7a) comprising three cooling circuits (7, 7a), i.e. two outer circuits (7) which are each accommodated in a longitudinal outer wall of a casing (8), adjacent to an outermost stator (3, 8), for cooling said outermost stator (3, 8), and an intermediate circuit (7a) located between the two innermost stators (3, 8) in the motor for simultaneously cooling said two stators (3, 8), the central shaft (5) being common to the two rotors (2) which are connected to the central shaft (5) by mechanical means.
