Abstract
The utility model discloses a star sealing device for a permanent magnet synchronous tractor of an elevator. The star sealing device comprises a main chip (1), wherein the main chip (1) is connected with a brake detecting module (2) and a tractor control module (3). According to the star sealing device, adopting the technical scheme and disclosed by the utility model, a braking torque can be generated for acting a braking effect and restraining the sliding speed or flying speed of the elevator under the condition that the permanent magnet synchronous tractor stops running due to power failure and a brake cannot stop the elevator owing to the fact that the brake is in failure, therefore the safety of the elevator is improved.
Description
Technical field
The utility model relates to a kind of envelope star device, relates in particular to a kind of envelope star device of elevator permanent magnetic synchronous traction machine.
Background technology
Permanent magnetic synchronous traction machine is little with its volume, good energy saving property and controlled good characteristics, has obtained Application and Development widely at elevator industry.
Existing permanent magnetic synchronous traction machine elevator; When the permanent magnetic synchronous traction machine dead electricity of operation and when shutting down, if go wrong can not be with elevator stopping for drg, elevator is having speed but is losing under the situation of driving torque; The phenomenon of slide car or driving can occur, reduce the safety of elevator.
The utility model content
The purpose of the utility model is, a kind of envelope star device of elevator permanent magnetic synchronous traction machine is provided.This device can shut down in the permanent magnetic synchronous traction machine dead electricity, and drg go wrong can not situation with elevator stopping under, produce a braking torque, play brake action, control elevator to slip the speed of car or driving the safety that has improved elevator.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of envelope star device of elevator permanent magnetic synchronous traction machine is characterized in that: comprise master chip, master chip connects drg detecting module and towing machine control module.
In the envelope star device of aforesaid elevator permanent magnetic synchronous traction machine, described drg detecting module comprises speed sensor and current sensor, and speed sensor all links to each other with master chip with current sensor.
In the envelope star device of aforesaid elevator permanent magnetic synchronous traction machine, described towing machine control module comprises contactless switch.
Compared with prior art; The utility model adopts technique scheme, can shut down in the permanent magnetic synchronous traction machine dead electricity, and drg go wrong can not situation with elevator stopping under; Produce a braking torque; Play brake action, control the speed of elevator slide car or driving, the safety that has improved elevator.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Description of drawings:
The 1-master chip, 2-drg detecting module, 3-towing machine control module, 4-speed sensor, 5-current sensor, 6-contactless switch.
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is further described, but not as the foundation to the utility model restriction.
The specific embodiment
Embodiment.A kind of envelope star device of elevator permanent magnetic synchronous traction machine, as shown in Figure 1, comprise master chip 1, master chip 1 connects drg detecting module 2 and towing machine control module 3.Drg detecting module 2 comprises speed sensor 4 and current sensor 5, and speed sensor 4 all links to each other with master chip 1 with current sensor 5.Towing machine control module 3 comprises contactless switch 6.
During use, the drg detecting module 2 of this device is installed on the drg, the towing machine control module 3 of this device is installed on the permanent magnetic synchronous traction machine.When elevator normally moved, this device was inoperative.Detect the permanent magnetic synchronous traction machine dead electricity and shut down at speed sensor 4 and current sensor 5; And drg go wrong can not situation with elevator stopping under; The contactless switch 6 of towing machine control module 3 is given short circuit with the three-phase winding wire of permanent magnetic synchronous traction machine armature, makes permanent magnetic synchronous traction machine inside can form an independently electric loop.Elevator will drive the permanent magnetic synchronous traction machine rotation like this; Make that the permanent magnet of static three-phase winding wire cutting rotation produces magnetic field and induces electro-motive force in the permanent magnetic synchronous traction machine; Thereby the formation braking torque plays brake action, controls the speed of elevator slide car or driving.
Claims (3)
