Embodiment Construction

[0021] figure 1 It is a side view of the motor 10 which concerns on one Embodiment of this invention. The motor 10 is placed vertically outdoors, that is, the side of the motor opposite to the load is located above the load side in the vertical direction. In addition, the central axis of the motor 10 does not need to completely coincide with the vertical direction, and the motor 10 may be installed such that the central axis is inclined from the vertical direction.

[0022] The motor 10 is mainly composed of a motor main body 12 , a load side cover 13 , a terminal box 16 , a fan (not shown), a fan cover 18 , and an umbrella member 20 .

[0023] The motor main body 12 is, for example, a cage-type induction motor, but may be other types of motors. Since the structure of such a motor is well known, detailed description thereof will be omitted in this specification. On the load side of the motor, for example, a planetary gear reducer is mounted.
