Description

The frequency control threephase asynchronous
Technical field:
The utility model relates to a kind of frequency control threephase asynchronous, is used for cigarette high speed cigarette making and tipping machine, belongs to field of power equipment technology.
Background technology:
Before the utility model was made, in prior art, the high speed cigarette making and tipping machine was to adopt DC motor to make transmission power source.Dc motor rotor is to adopt the Wound-rotor type structure, and rotor applies exciting current by carbon brush, and passes to the rotor winding through commutator and form magnetic field and rotate.Though the motor speed adjusting performance of this kind structure is better, its structure is complicated, make and safeguard trouble, and the armature of price height, particularly DC motor contact with carbon brush and easily produces carbon distribution, must periodic maintenance could guarantee normally to move.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned weak point, thereby provides a kind of simple, compact and reasonable for structure; Low cost of manufacture, volume is little, operation and need not safeguarding continuously when long; Good cooling results, the frequency control threephase asynchronous that speed adjusting performance is reliable and stable.
Main solution of the present utility model is achieved in that
The utility model mainly comprises stator 11, rotor 10, cover plate 6, protective cover 18, it is characterized in that adopting rotor 10 to be fixed on the front and rear cover 9,22, front and rear cover 9,22 is fixedlyed connected with stator 11, terminal box 17 is housed on stator 11, cover plate 6 is fixed on the front and rear cover 9,22, at front end housing 9 and 8 on bearing wavy spring sheet 7 is housed, internal bearing cover 12 is installed on the front and rear cover 9,22, and protective cover 18 is housed on the rear end cap 22.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Low cost of manufacture, volume is little, and is easy for installation; Owing to adopted cage-type rotor, operation and need not safeguard that operation and maintenance cost is lower continuously when motor can be grown; Good cooling results, speed adjusting performance is stable, and can improve the reliability of complete machine.

Embodiment:
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
The utility model adopts rotor 10 to be fixed on the front and rear cover 9,22 by bearing 8, and its rotor 10 comprises parts such as axle and rotor core.Front and rear cover 9 is fixedlyed connected with stator 11 by bolt, packing ring.Stator 11 comprises parts such as stator core and support.Cover plate 6 adopts screw 4, packing ring 5 to be fastened on the front and rear cover 9,22.On rotor 10 joint outer parts, key 3 is housed.Wavy spring sheet 7 is contained between bearing 8 and the front end housing 9 and prevents from axially to wear.Internal bearing cover 12 adopts bolt 13 to be contained on the front and rear cover 9,22, hanger 4 on the packing ring 16 fastening front end housings 9, is installed terminal box 17 by bolt 15 on stator 11, protective cover 18 is fastened on the rear end cap 22 by packing ring 19, and front and rear cover 9,22 is fastened on the stator 11 by bolt 20, packing ring 16.Air inlet seal felt 21 is installed on the front end housing 9, is shaped on installing hole 23 respectively on front and rear cover 9,22, is convenient to install nameplate 2 and adopts rivet 1 to be fastened on the stator 11.
The working range of the utility model frequency control motor is big, motor is a speed regulation by constant torque with 0-3000r/min, 3000r/min is above to be constant-power speed regulation, satisfied the requirement of speed regulation by constant torque when the high speed cigarette making and tipping machine runs up, be that general frequency control motor institute is unappeasable, and possess the good speed adjusting performance of DC motor.
