Abstract

The invention provides low-speed permanent magnet synchronous motor direct-drive variable-frequency speed regulation ore grinding equipment, which comprises ore grinding equipment, a low-speed permanent magnet synchronous motor for driving the ore grinding barrel of the ore grinding equipment to rotate and a variable-frequency speed regulation control system of the low-speed permanent magnet synchronous motor, wherein the rotor of the motor is composed of a semicircular rotor upper section and a semicircular rotor lower section which can be combined into a circular ring, the rotor is arrangedbetween the end face of the ore grinding barrel and an end cover, and is fixedly installed on the ore grinding barrel through a roller connecting bolt, the stator of the motor is composed of a statorupper section and a stator lower section which can be combined to form a circular inner hole, the stator lower section is arranged in a base, lapping lugs on the two sides are fixedly installed on bearing tables on the two sides of a notch of the base, and the stator sleeves the periphery of the rotor. The low-speed permanent magnet synchronous motor direct-drive variable-frequency speed regulation ore grinding equipment is simple in structure, safe, reliable, convenient to maintain and capable of saving operation cost.

Description

technical field [0001] The invention belongs to the technical field of ore grinding equipment, and in particular relates to an ore grinding equipment directly driven by a permanent magnet synchronous motor with frequency conversion and speed regulation. Background technique [0002] The structure of traditional grinding equipment is mostly motors, reducers, large and small gears, and grinding equipment cylinders are connected to each other through intermediate mechanical transmission parts. There are many transmission connections and complex structures. Tune. With the development of permanent magnet synchronous motor and frequency conversion speed regulation technology, it is possible to use low-speed permanent magnet synchronous motor to directly drive the cylinder of the grinding equipment, simplify the structure of the grinding equipment, further improve the safety and reliability of equipment operation, and reduce the operating cost of equipment. .
