Description
Technical field:
The present invention relates to explosion separation motor field, particularly to a kind of double-stator and double-rotor explosion separation motor.
Technical background:
Explosion separation motor is a kind of a kind of motor that can use in inflammable and explosive place, is mainly used in colliery, oil sky
So field such as gas, petrochemical industry and chemical industry.The profile chi of the explosion separation motor that the manufacturer of explosion separation motor provides according to user
Very little and parameter needs to carry out producing motor, and in colliery field, the environment of mine differs, and the size dimension for explosion separation motor needs
Summation power demand also differs.So, during design motor, determine that key dimension is the key of design, key dimension determines
Afterwards, other sizes also just can substantially determine, the key dimension of motor refers to diameter and the length of armature core.Different for three
For step motor, key dimension refers to frame bore.Want effectively to utilize stator core, its internal diameter, external diameter and length
Reasonable ratio determine electromagnetic performance, operating characteristic and the operational reliability of motor.
Produce underground mine use Flame-Proof Three-Phase Induction Motors, overall dimensions and the technology being provided according to user is provided
Parameter is designed.Because mining motor is limited by factors such as Underground working site space, safety, when motor overall dimensions are true
After fixed, not only the every technical performance of satisfaction to be calculated by electromagnetism and reach industry or company standard requirement, and structure to be passed through
On ingehious design come to guarantee motor profile meet user require.
With power 315kw, as a example voltage 1140v motor, by user profile dimensional requirement, this motor length value is diameter value
More than 2 times, determine that this motor belongs to slender type.Calculated by rational electromagnetism, if finding that the overall dimensions of this motor are designed to
Power is 315kw, a stator, the normal mode of a rotor, and in its electromagnetism result of calculation, many parameters are very poor, can not meet
The requirement of standard.If optimizing these parameters, motor rotary shaft diameter can be less, because motor is elongated, allows for motor in fortune
By the deflection of rotor weight and generation during turning, easily produce air gap inequality, and then produce unilateral magnetic force, lead to turn
Shaft deflection increases with unbalanced the increasing of magnetic pull, causes shaft bending to deform, produces and sweep thorax phenomenon, until motor burns
Ruin, greatly reduce running reliability of motor.
Content of the invention:
In view of this, in order to overcome drawbacks described above it is necessary to provide a kind of double-stator and double-rotor explosion separation motor.
A kind of double-stator and double-rotor explosion separation motor, including the first rotor, the second rotor, the first stator, the second stator, transmission
Axle, binding post, rosette, housing, end cap and bearing cap, the first rotor and the second rotor are connected in turn on power transmission shaft, the
One stator sleeve is contained on the first rotor, and the second stator is sleeved on the second rotor, and binding post is fitted in rosette, end cap and
Bearing cap is fitted on housing, and three main leads of three main leads of the winding of the first stator and the winding of the second stator adopt
It is connected with binding post with item mode in parallel.
Preferably, leave wiring gap between the winding of the winding of the first stator and the second stator.
Preferably, the winding of the first stator is separate with the winding of the second stator, equipped temperature on the winding of the first stator
Degree sensor, the winding of the second stator is equipped with temperature sensor.
It is 315kw that the present invention effectively solves power, and the design difficulty of the explosion separation motor of voltage 1140v, in electro permanent magnetic
Can go up and meet the requirement of output, effectively save the use of raw material and so that whole machine installation difficulty is substantially reduced.
