Example Embodiment

[0025] In the following, the present invention will be further described in conjunction with the drawings and specific implementations. It should be noted that, provided that there is no conflict, the following embodiments or technical features can be combined to form new embodiments. .

[0026] Such as figure 1 As shown, a permanent magnet linear motor 100 includes a primary assembly 10 and a secondary assembly 20.

[0027] Such as Figure 2-6 As shown, the primary assembly 10 includes a body 11, a cooling connector 12, a power connector 13, a primary iron core 14, a coil winding 15, a primary potting compound 16, a connecting rod 17, a connecting block 18 and a cooling channel 19.

[0028] The body 11 includes a front protective plate 111, a rear protective plate 112 and a top mounting plate 113. The front protective plate 111 and the rear protective plate 112 are threadedly connected to both ends of the body 11 to form a cavity. A connecting hole 114 and a threaded hole 115 are...

Abstract

The invention discloses a permanent magnet linear motor, which includes a primary assembly, the primary assembly includes a machine body, a primary iron core, a plurality of coil windings, cooling joints and cooling channels, a plurality of coil windings are connected to each other and fixed on the primary iron core, the primary iron core and the body It is fixedly connected and located inside the machine body. The cooling joint is fixed at one end of the machine body. The outer wall of the cooling channel is close to the primary core and several coil windings. The cooling channel includes the top cooling channel and the side cooling channel. One end of the side cooling channel is connected to the top cooling channel. The flow channel is connected, and the other end is connected with the cooling joint, and the hole diameter of the cooling flow channel is larger than the hole diameter of the cooling joint. In the present invention, the cooling channel is closely attached to the primary iron core and the coil winding, directly cooling the heat source, and the effect is good; the aperture of the cooling channel is larger than the aperture of the cooling joint, which increases the amount of refrigerant in the cooling channel and effectively suppresses the temperature rise of the body; in addition, the side The cooling channel cooperates with the top cooling channel to further increase the volume of the refrigerant stored in the body.

Description

technical field [0001] The invention relates to a mechanical motor, in particular to a permanent magnet linear motor. Background technique [0002] Permanent magnet linear motors have the dual characteristics of permanent magnet motors and linear motors. They have the characteristics of large thrust, high speed, and small size. They are the first choice for high-speed and high-precision linear feed systems. At present, permanent magnet linear motors are more and more widely used in industrial machinery such as machining centers, PCB drilling machines, forming machines, electrical discharge machines, and gantry systems. In order to solve the problem of poor thermal shock performance, there are usually the following methods: increase the refrigerant flow rate, use a larger refrigerant flow rate to quickly take away the heat from the motor; isolate the machine from the primary component, use other cooling devices to separate the primary and The machine is isolated to prevent t...
