Abstract

The invention relates to a motor of a dragline scraper. The motor comprises a shell, a stator, a rotor, a fan, a fan cover and a storage battery, a rotating shaft is arranged in the middle of the shell, and the stator is arranged at the outer side of the rotor; a partition plate is arranged at one end in the shell, the fan is arranged on one side of the partition plate, and the stator and the rotor are arranged at the other side of the partition plate; the fan cover is arranged at the outer side of the fan, the storage battery is arranged below the fan, and the heat dissipation ribs are distributed on the outer wall of the shell in a radial direction; an outer cover plate covers the heat dissipation ribs, the heat dissipation grooves and the heat dissipation holes are arranged on the outercover plate, the heat dissipation fins are arranged in the heat dissipation grooves, and the heat dissipation fins and the heat dissipation holes are arranged in a staggered manner. Through the motordesigned by the invention, the problem of the circuit burnout caused by the over-high temperature can be effectively avoided, so that the use safety and stability of the dragline scraper are greatlyimproved.

Description

technical field [0001] The invention relates to the field of engineering machinery power systems, in particular to a dragline excavator motor. Background technique [0002] With the rapid development of social economy, people have higher and higher requirements for the quality of life and living environment. At present, construction machinery has become an indispensable tool for large-scale project construction and urban rescue. The number of construction machinery and equipment is also increasing. At the same time, as we all know, most construction machinery now uses fuel to drive the engine to run, which will generate a lot of exhaust gas during use, thus promoting the generation of draglines. [0003] As the main component of precision machinery, the motor of construction machinery has a crucial influence on the working accuracy of the actuator, so it has become a new industrial requirement to accurately detect the working state of the motor. Dragline refers to the use ...
