Abstract

The invention discloses a flame-proof type frequency conversion integrated permanent-magnet synchronous motor, which comprises a motor base and a frequency conversion control cabinet, wherein the frequency conversion control cabinet is welded on the motor base; and a frequency converter is mounted in the frequency conversion control cabinet. The inside of the frequency conversion control cabinet is divided into a first cavity, a second cavity and a third cavity through separation plates; the motor base comprises a cylinder and an end cap; the cylinder is formed by an inner cylinder and an outer cylinder which are sleeved together; the inner cylinder and the outer cylinder are integrally welded in an interference fit manner; a spiral groove is formed on the outer cylinder surface of the inner cylinder; the end cap comprises a first end cap and a second end cap which are respectively located at two ends of the cylinder and a third end cap located inside the cylinder; a rotor and a stator are arranged between the first end cap and the third end cap; and an input reactor and an output reactor are arranged between the third end cap and the second end cap. The permanent-magnet synchronous motor is novel in structure, is reasonable and compact, can effectively utilize the limited space, is compact in product structure, high in power factor, efficiency and power density, and can effectively reduce the motor volume and the energy consumption.

Description

technical field [0001] The invention relates to a flameproof frequency conversion integrated permanent magnet synchronous motor, which is mainly used in coal mining equipment such as coal plows, scraper machines and belt conveyors in coal mines. Background technique [0002] At present, the frequency conversion integrated motors used in coal mining equipment such as coal mine plows are all frequency conversion integrated asynchronous motors imported from abroad, and there is no similar product in China. Due to the high price of imported frequency conversion integrated motors, troublesome maintenance, technical limitations, trade protectionism and other factors, in addition, compared with permanent magnet synchronous motors, asynchronous motors have lower power density and efficiency, which is not conducive to reducing the size of the motor. size and reduce energy consumption. Contents of the invention [0003] The purpose of the present invention is to provide a permanent...
