Abstract

The utility model discloses a three-speed motor. The three-speed motor comprises a shell, end covers, a stator winding, a rotator component and a control center, wherein the end covers are fixedly arranged at the two ends of the shell; the stator winding and the rotator component are fixedly arranged on the inner surface of the shell; two junction boxes are arranged outside the shell; 9 wiring terminals are arranged in each junction box and are connected with the control center in a control way; a plurality of temperature sensors are embedded in the stator winding and is connected with the control center in a control way; and different mark numbers are arranged on the wiring terminals respectively and correspond to wiring terminals on the control enter one by one. Due to the adoption of the three-speed motor and the temperature sensors which are arranged in the motor, the temperature in the motor can be monitored in real time through the control center, the control center controls the motor to stop when the temperature in the motor is more than set value, the safe running of the motor is ensured; at the same time, the mark numbers corresponding to the wiring terminals of the control center one by one are marked on the wiring terminals of the motor, so a wiring error caused by an operator is avoided.

Description

A kind of three-speed motor
Technical field
The utility model relates to a kind of three-speed motor, particularly relates to a kind of three-speed motor with automatic protection functions that is used for the subway tunnel blower fan.
Background technology
For the subway tunnel blower fan; Owing under different working conditions, need to adopt different rotating speed, regulate the rotating speed of subway tunnel blower fan like the mode that adopts VFC, not only cost of investment is bigger; Frequency-variable controller also belongs to the parts that damage, and can influence the ventilation of subway tunnel.For this reason, present subway tunnel blower fan generally adopts three-speed motor, as adopts the three-speed motor of 4/6/8 utmost point, can realize three kinds of rotating speeds of subway tunnel blower fan, can realize basically that it is to the work under the different operating modes.Because the subway tunnel blower fan need work long hours sometimes, when the blower fan operating time was longer, the temperature in its motor can raise; When temperature raises above behind the certain value, cause the damage of motor easily, simultaneously; Existing three-speed motor has nine binding posts usually; Could realize that through certain mode of connection motor turns round under three kinds of speed, but only mark 1-9 numeral on its binding post usually, the manufacturer who has even nine binding posts are not marked; When blower fan was installed, the accident of blower fan counter-rotating even burn-down of electric motor appearred causing because of wiring error through regular meeting.
The utility model content
For overcoming above-mentioned defective, the utility model aims to provide a kind of after the motor internal temperature rise surpasses the linchpin definite value, motor stall automatically, and be not easy to cause the three-speed motor of wiring error.
For achieving the above object; The technical scheme that the utility model adopts is: a kind of three-speed motor; Comprise casing, be fixed on the end cap of casing two ends, the stator winding that is fixed in casing inner surface and rotor assembly, said casing has two terminal boxes outward, has nine binding posts in the said terminal box; The three-speed motor of the utility model also comprises a control centre; Said binding post and control centre's control connection, said stator winding is embedded with the plurality of temperature transducer, said temperature sensor and control centre's control connection.
Said temperature sensor is two, and said temperature sensor places stator winding near end caps respectively.
Have different labels on the said binding post respectively, said label is corresponding one by one mutually with binding post in the control centre.
Adopted the three-speed motor of the utility model,, can monitor the temperature of motor internal in real time through control centre owing to be provided with temperature sensor at motor internal; When the motor internal temperature rise surpasses set point; Control centre's control motor is shut down, and guarantees the motor safety operation, simultaneously; On the binding post of motor, put on and the binding post of control centre label one to one, avoided operating personnel's wiring error.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the connection terminal structure sketch map of the utility model.
Among the figure: 1-casing, 2-end cap, 3-stator winding, 4-rotor assembly, 5-terminal box, 6-binding post, 7-temperature sensor, 8-control centre, 9-label, 10-binding post, 11-sign.
Embodiment
As shown in Figure 1; The utility model discloses a kind of three-speed motor; Comprise casing 1, be fixed on the end cap 2 of casing 1 two ends, the stator winding 3 that is fixed in casing 1 inner surface and rotor assembly 4, have two terminal boxes 5 outside the said casing 1, have nine binding posts 6 in the said terminal box 5; In sum, with the structure basically identical of existing three-speed motor.
The innovative point of the three-speed motor of the utility model is that mainly it also comprises a control centre 8; Said binding post 6 and control centre's 8 control connections; Be exactly binding post 6 specifically with the corresponding one by one mutually electrical connection of binding post in the control centre 8 after; Can carry out the control that three speed turn round and shut down to motor through control centre 8, said stator winding 3 is embedded with plurality of temperature transducer 7, said temperature sensor 7 and control centre's 8 control connections.Temperature in motor raises, and when exceeding set point, temperature sensor 7 sends signal and gives control centre 8; Control centre 8 cuts off the power supply of motor immediately, makes the motor stall, after motor is passing through the shutdown of certain hour; When its internal temperature drops to working temperature; Temperature sensor 7 sends signal and gives control centre 8, and the power supply that control centre 8 recovers motor makes motor rotation.
In practical application, the said temperature sensor 7 of the three-speed motor of the utility model can be two usually, and said temperature sensor 7 places stator winding 3 near end cap 2 places respectively.Place stator winding 3 can guarantee accurate monitoring basically with less temperature sensor respectively to the motor internal temperature near two temperature sensors 7 at end cap 2 places.
Usually on the binding post 10 of control centre 8, have certain sign that is used to distinguish 11; As shown in Figure 2; Have different label 9 respectively on the said binding post 6 of the three-speed motor of the utility model, said label 9 is corresponding one by one mutually with binding post 10 in the control centre 8.That is to say that the label 9 on the binding post 6 is identical with sign 11 on control centre 8 binding posts 10; Like this; Operating personnel only need to connect one to one label on the binding post 69 and sign 11 on the binding post 10 mutually when carrying out line and can guarantee the accurate of wiring; Both convenient, avoided the generation of wiring error again.
