Abstract

PURPOSE:To obtain a motor which has good cooling effect in a totally enclosed opposite fan-cooled type rotary electric machine by providing a vent passage which is partly passed elevationally at an oil reservoir of an upper bearing and guiding cooling air of the machine through the vent passage to a stator frame. CONSTITUTION:Cooling air is guided through an upper outer fan 11 and a vent passage provided in an oil reservoir 13 to the top of s stator frame 15. Here, the vent passage 14 provided circumferentially is distributed uniformly on the periphery to cool a cooling fin 16 and to exhaust externally. According to this structure, even if the reservoir 13 is larger than the frame 15, the vent passage can be smoothly formed, and the waste of the stream of the cooling air can be eliminated. Accordingly a rib cooling sturcture can be adapted for a motor of relatively small size.

に制限があるため、リブ冷却構造の適用が困難であった
。従って、第１図に示すような熱交換器１を備えた冷却
方式の電動機を採用していた。Conventionally, in upper bearings with oil lubrication, there is a limit to the size of the oil reservoir, making it difficult to apply a rib cooling structure. Therefore, a cooling type electric motor equipped with a heat exchanger 1 as shown in FIG. 1 has been adopted.

溜である。According to this structure, even if the upper bearing oil sump is larger than the stator frame, the ventilation passage can be smoothly formed, and the flow of cooling air is also less wasteful. Therefore, a lip cooling structure suitable for a relatively small electric motor can be provided. In addition, in the figure, 12 is a cooling pipe, and 13 is an oil reservoir.

A circumferential ventilation passage 21 on the cooling air intake side of the upper part of the stator frame is provided on the outer periphery of the cooling fin. The advantages of this modification are that the cooling fins can be used all the way to the stator frame, resulting in a large cooling effect, and that the shape and size of the ventilation passages can be freely selected as needed, so more effective cooling can be expected. It is in.
