Abstract

PURPOSE:To reduce noise and to further eliminate the suction of rainy water by cooling a heat pipe inserted into the primary core. CONSTITUTION:Suitable number of holes 2 are formed at a laminated core which forms the primary core in the thicknesswise direction of the laminated core. Independent heat pipes 3 are respectively inserted into the holes. The pipe 3 has threaded portions 4 at both ends, the pipe 3 is inserted into the hole 2 to project the threaded portions 4 from the both ends of the primary core 1, a nut 5 is inserted into the threaded portion 4 to clamp the both side ends of the core 1. A heat sink fin 6 is mounted by clamping at the portion 4. With this construction, a noise can be eliminated, and the suction of the rainy water can be obviated.

れている。(b) Prior art and its problems Since linear motors have a large air gap length, it is necessary to have a large current density in the primary winding in order to obtain a specified thrust.
It usually reaches 5-l QA/mxn2. As a result, the amount of heat generated is excessive, so conventionally air cooling using a fan has been performed.

Furthermore, since rainwater is sucked in by the fan, when used outdoors, there are problems such as deterioration of the insulation performance of the motor.

ある。(C) Means for Solving the Problems In order to solve the above problems, the present invention provides a primary core made of a laminated core with holes penetrating in the thickness direction of the laminations.
A heat pipe having threaded portions at both ends is inserted into the hole, a nut is fastened to the threaded portion protruding from both sides of the primary core, and a radiation fin is attached to the threaded portion. The heat pipe is used not only for cooling, but also for tightening the laminated iron core.
