Description
Technical field
The present invention relates to the technical fields of traction machine.
Background technique
Country's elevator industry dog-eat-dog at present, more more and more universal with present elevator, elevator(lift) machine room is also by original
Big computer room is changed to small room, machine room development, and the heat dissipation problem for how improving elevator traction machine also becomes the urgent of industry development
Demand.
Chinese patent 201410385700.7 describes a kind of permanent magnetic synchronous traction machine with aeration structure, the traction machine machine
Seat is provided with ventilation hole, is equipped with fan quenching in a ventilation hole, this scheme can be effectively reduced motor temperature rise,
But the technical solution the problem is that: fan does not control, and connects electricity and just runs, long-term work will lead to the lost of life.
Summary of the invention
It is an object of the invention to provide a kind of, and automatic running is cold according to traction machine temperature and under operational state of mainframe
But, the elevator traction machine of fan service life can be extended.
The invention is realized in this way being placed in circle including base, the circular stator being arranged on base, cyclic annular outer rotor
Outside annular stator, the two sides of base are equipped with brake, and base section is in " huge " shape, and stator cantilever is fixed on " huge " font
The center of base, the stator winding end of circular stator and the annular side of base are adjacent and form certain gap, field ring
Top, the lower section of shape side are provided with ventilation hole, its special feature is that: lower section ventilation hole is provided with fan, fan blowing
Direction to base inner, fan power supply input terminal concatenates in parallel with brake power input after a thermoswitch, and temperature-sensitive is opened
Pass is fixed on base or is fixed on stator or fixes on the brake.
Working principle
When fan is run, cold air passes through fan from ventilation hole entrance → and stator winding end contact → warp below base
Cross temperature after stator winding end is contacted with the annular gap of base inner face flowing → cold air with winding increase naturally → it is cold
Air becomes hot-air and forms ascending air → ventilation hole discharge right above the base, forms cooling circuit, normally opened temperature-sensitive
Switch is fixed on base or is fixed on stator or fixes on the brake.
In view of fan long-term work can shorten the service life, a normally opened temperature-sensitive is then concatenated in the input circuit of fan and is opened
It closes, in parallel with brake power input, when elevator prepares to run, brake guaranties band-type brake is opened, and traction machine starts running,
If temperature is lower, normally opened thermoswitch is in an off state, and fan does not work, and is set when detection position temperature reaches thermoswitch
When determining temperature, thermoswitch is connected, and traction machine operation, fan work cools down traction machine.
Beneficial effect
1. forming cooling circuit, traction machine good heat dissipation effect by forced ventilation.
2. only in traction machine operating condition and when temperature reaches setting temperature, fan is just run, long service life, reality
Now automatically control.
3. stator or rotor are there are when failure, by ventilation hole, the machine that can not tear open is repaired.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention；
Fig. 2 is the right view of Fig. 1；
Fig. 3 is shaft side figure of the invention；
Fig. 4 is elementary diagram of the invention.
Specific embodiment
Now in conjunction with drawings and examples, present invention is further described in detail:
As shown in Figure 1, 2, 3, the present invention include include base 3, the circular stator 4 being arranged on base 3, cyclic annular outer turn
Son 5 is placed in outside circular stator 4, and the two sides of base 3 are equipped with brake 2, brake bush 2a and rotor outer surface 5a
Contact, 3 section of base are in " huge " shape, and 4 cantilever of stator is fixed on the center of the base 3 of " huge " font, the stator of circular stator 4
Winding overhang 4a is adjacent with the annular side of base 3 and forms certain gap, and top, the lower section of base annular side are provided with
Ventilation hole 3a, its special feature is that: lower section ventilation hole 3a is provided with fan 1, and there are two the ventilation hole 3a of top, is located at base
3 annular sides both sides (can effectively enhance heat dissipation effect, shorten the continuous working period of fan, meanwhile, it is convenient logical by this
Air port is safeguarded by stator), to inside base 3, wind direction is as shown by arrows in the direction that fan 1 is dried.
In the present embodiment, normally opened thermoswitch 6 is placed on brake 2, and is connected with 1 input circuit of fan, with system
Dynamic device power input is in parallel, and schematic diagram is shown in Fig. 4, and when elevator prepares to run, 2 energization band-type brake of brake is opened, and traction machine is opened
Begin to operate, if brake temperature is lower, normally opened thermoswitch is in an off state, and fan does not work, when brake temperature reaches
When to thermoswitch set temperature, thermoswitch closure, when giving brake guaranties, fan work cools down traction machine.
Normally opened thermoswitch 6 can be fixed on base 3 or be fixed on stator 4 or be fixed on brake
On 2.
