Problems solved by technology

[0005] Purpose of the invention: The purpose of the present invention is to provide an outer rotor switch reluctance direct drive drum, the overall structure design is reasonable, and solve the problem of the existing traditional drum motor and reducer in the open drive device outside the driving drum, the problem of complex structure, The three-phase asynchronous drum motor has a large starting current (close to 200A), low starting torque, and difficult speed adjustment. When the drum motor is running, it produces a lot of noise, consumes a lot of power, has weak sealing performance, takes up a lot of space, and is difficult to install. There are many problems with maintenance, and its operation status is stable and its safety factor is high.

Abstract

The invention belongs to the technical field of roller motor application, and particularly discloses an outer rotor switch reluctance direct drive roller, which comprises a shaft, a stator, a rotor, aroller, a first bearing, a second bearing, a first bearing inner cover, a second bearing inner cover, a first bearing outer cover, a second bearing outer cover, a group of shaft seats, a sensor seatand a sensor. The outer rotor switch reluctance direct drive roller has the advantages that 1, low-speed direct drive is achieved, a speed reduction system is omitted, a transmission chain is simplified, and reliability is high; 2, the speed is low, the torque is large, start and stop are stable, and overload start can be realized; 3, a mechanical deceleration system is omitted, the structure is simple and compact, and the occupied space is small; 4, the use and maintenance are convenient, the operation is safe and reliable, demagnetization is avoided, and the service life is long; 5, full-vector control is realized, operation modes are diversified, and accurate control and adjustment characteristics are realized; 6, the roller has higher comprehensive efficiency, and is efficient and energy-saving; 7, during multi-machine operation, power balance can be realized; and 8, a motor runs as usual without being burnt due to lack of items.

Description

technical field [0001] The invention belongs to the technical field of drum motor applications, and in particular relates to an outer rotor switched reluctance direct drive drum, which is widely used in industries such as metallurgy, mining, papermaking, coal, steel, building materials, electric power, chemical industry, transportation, and road construction machinery. Background technique [0002] At present, the production of the machinery industry is showing a trend of rapid growth. The main purpose of the three-phase asynchronous drum motor is as the power source of the equipment to make the equipment run normally. The drum motor is widely used. The drum motor is widely used in various industries as the active roller, such as Coal and ash transportation in steel mills, water pump operation in power plants, etc. [0003] At present, the electric drum produced in our country can be divided into two categories, one is the ordinary electric drum with the motor inside the dru...
