Abstract

The present invention discloses an annular permanent magnetism gearless ball mill direct drive motor, and belongs to the ball mill drive equipment technology field. The direct drive motor comprises a stator and a rotor, wherein the rotor is fixedly installed on the outer surface of a ball mill cylinder via a block type rotor iron core and is concentric with the ball mill cylinder, the stator is a sectional stator, is laminated and spliced into a whole circle to sleeve the periphery of the rotor and is concentric with the rotor, and the block type rotor iron core is formed by laminating and splicing small fan-shaped punching sheets. A part of magnetic steel of the rotor is wrapped in a pole shoe, the other part is embedded in the rotor iron core, and air magnetic insulation grooves are arranged between the fan-shaped punching sheet structures and the ball mill cylinder. According to the present invention, the gear transmission mechanisms, such as a reducer, a small gear, a large gear ring, etc., in the conventional ball mill are canceled, thereby effectively improving the transmission efficiency of a system, avoiding and reducing the maintenance work of the gears, prolonging the overhauling cycle and the service life of the equipment, and improving the reliability of the equipment.

Description

technical field [0001] The invention relates to an annular permanent magnet gearless ball mill direct drive motor, which belongs to the technical field of ball mill drive equipment. Background technique [0002] In industrial production, especially in heavy industrial production, ball mills, as key equipment in the production of material crushing operations, are widely used in related industries such as mineral processing, cement, silicate products, new building materials, refractory materials, chemical fertilizers, and glass ceramics. . In traditional ball milling equipment, the transmission method used is mainly open peripheral gear transmission, that is, a wound asynchronous motor is used to drive the reducer—the reducer (or a large wound synchronous motor) drives the pinion—the pinion and the The transmission mode in which the large ring gear installed on the mill drum meshes to drive the mill to run. In this driving mode, there are many defects such as low transmissio...
