Abstract

The invention relates to a large-scale excavator motor, which includes a casing, a stator, a rotor, a fan, a windshield and a storage battery. A rotating shaft is arranged in the middle of the casing, the stator is arranged outside the rotor, and One end is provided with a baffle, one side of the baffle is provided with the fan, the other side of the baffle is provided with the stator and the rotor, and the windshield is provided outside the fan, so The storage battery is arranged below the fan, the outer wall of the housing is radially distributed with cooling ribs, the cooling ribs are covered with an outer cover plate, and the outer cover plate is provided with cooling grooves and cooling holes. A cooling fin is provided, and the cooling fin and the cooling hole are arranged in a dislocation manner. The motor designed by the invention can effectively avoid the occurrence of the circuit burning problem caused by excessive temperature, thereby greatly improving the safety and stability of the large excavator.

Description

technical field [0001] The invention relates to the field of engineering machinery power systems, in particular to a large 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, which will generate a lot of exhaust gas during use, thus promoting the production of large excavators. [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. Large excavators refer to the ...
