Abstract

The invention relates to an internal drive type electromagnetic roller and an electromagnetic roller heat dissipation method, the internal drive type electromagnetic roller comprises a central shaft, a roller, a permanent magnet, a stator core, a coil, a fan and a transmission assembly, the fan and the transmission assembly are rotatably installed on the central shaft, the stator core, the coil and the fan are located in the roller, the stator core is provided with a central hole, and the permanent magnet is arranged in the central hole. A cavity communicated with the two ends of the stator core is formed between the inner wall of the center hole of the stator core and the center shaft, the fan is located at one end of the center hole, fan blades of the fan face the center hole, and the roller is connected with the fan through the transmission assembly so as to drive the fan to rotate. The internal drive type electromagnetic roller and the electromagnetic roller heat dissipation method have the advantages that the electromagnetic roller is simple in structure, convenient to use and good in heat dissipation effect.

Description

technical field [0001] The invention relates to the technical field of electromagnetic drums, in particular to an internal drive electromagnetic drum and a heat dissipation method for the electromagnetic drum, which are applied to industries such as petroleum, mining, metallurgical steel rolling and the like. Background technique [0002] The electromagnetic drum has the advantages of simple mechanism, reliable operation, low loss, high efficiency, and direct drive control. When the outer rotor electromagnetic drum is working, the coil installed on the stator will generate a large amount of induced heat, which will easily lead to motor aging and affect the service life of the outer rotor electromagnetic drum. The outer rotor electromagnetic drum mainly relies on the cooling water circuit inside the stator, and the drum is cooled by an external water cooler or an external water source. The cooling method is single and the heat dissipation area is limited. [0003] In order t...
