Embodiment Construction

[0027] The invention provides a linear motor liquid cooler with fast cooling speed, high efficiency, compact structure and space saving. The cooler is a plug-in inner cooler, and the cooling device for a linear motor will be described in detail with reference to the accompanying drawings. In the assembly diagram of the internal cooling cooler shown in Figure 1, the cooling water pipe 3 is inserted into the wire release slot of the iron core 1 and is close to the coil 2. The liquid channel 3.1 is connected by the external connector 7, and then forms a cooling circuit with the water inlet 5 and the water outlet 6 of the cooling liquid; Good filler.

[0028] The cooling water pipe has two kinds of dual cooling liquid channels (as shown in Fig. 2 and Fig. 3(a) and (b)) and single cooling liquid channel (as shown in Fig. 5).

[0029] The communication of the dual coolant channels is in the form of an external channel communicator 7 (as shown in FIG. 2 ) and a communication hole 8...

Abstract

This invention relates a linear motor cooler. The cooling water tube of the cooler is inserted into the iron-core of the motor and placed in the wire trough close to the coil. The two cooling water tubes are connected by a connecting piece. The double cooling liquid pass-way of the other end of the cooling water tube is connected by an external connector. An then connected are inlet and outlet to form a complete cooling loop. Then the same is linked with an external circulation cooler. The advantages are: quick cooling, high efficiency, compact structure and small space occupation.

Description

technical field [0001] The invention belongs to the technical scope of motor cooling, and in particular relates to a linear motor cooler aiming at the unique structural characteristics of the linear motor. Background technique [0002] Linear motors are zero-transmission systems that directly generate high-speed motion. Compared with rotary motors, they are more likely to generate heat, especially for high-thrust linear motor systems. When linear motors are used on machine tools, they are often sealed to avoid inhaling a large amount of magnetic dust due to the strong magnetic field of linear motors. Sealed use makes the heat dissipation conditions of linear motors worse. The heating problem directly affects the fast response of the linear motor, limits its maximum rated thrust, and changes the operating point of the permanent magnet. It has become a bottleneck problem restricting the development of linear motors. Therefore, it is necessary to develop an efficient cooling ...
