PURPOSE:To improve the cooling performance of a stator by providing a through hole for connecting between adjacent stator side spaces at an intermediate bracket. CONSTITUTION:A plurality of rotors are mounted on one motor shaft, stators corresponding to the rotors are individually sealed by cans, thereby forming a liquid-sealed motor. An intermediate bracket which has bracket units 13a, 13b for holding radial bearings at both end sides and a base 13c is disposed between the stators, and through holes 15 are formed at the solid unit except a recess of the base 13c. A hole 17 for leading power supply wirings 16 to a stator is formed at one of the holes 15, and the hole 17 is blocked by a blocking plate 19. The both spaces of the stators are connected via the holes 15, thereby circulating liquid in the both spaces through the holes 15. |
