Machine tool equipment electrical troubleshooting - for appearance inspection fault area

In determining the scope of the possibility permanent magnet generator of failure,for within the scope of the electrical components and wires are appearance inspection,such as:the melt blown fuse;The location of the travel switch adjustment is not appropriate;Wire connector is loose or fall off;Contactor and relay contactor fall off or poor contact,coil burn 12v motor discoloring the burning surface electric motor insulation paper,flashing the insulating varnish outflow;Spring falls off or broken;Electrical switch,acmotortrading.blogspot.com etc.,the action mechanism of blocked failure can clearly show that point of failure.

WTD/YBT/YTD series elevator motors

Using permanent magnet synchronous motor of elevator traction system,usually a gearless traction.Highlight the permanent magnet synchronous motor is easy to make the advantages of low speed and high power.Its compact structure,complete functions,traction motor,traction wheel,electromagnetic brake,in a photoelectric encoder,and easy to install,easy to use.Especially in the development and application of machineroomless elevator,the permanent magnet synchronous electrical motor 12v 1000w traction motor installed in the hole of the lift,the room of construction cost is saved,and beautify the appearance of the building.The wholesalemotor.blogspot.com control chart is shown in figure 4.When the load changes,the permanent magnet synchronous motor by adjusting the Angle between 8 to adapt,its response is fast.

In order to make the elevator has the good comfortable starting and brake and leveling accuracy,joined the accurate rotor and stator rotor position in the system unit and voltage current detection device,determine the size of the motor magnetic field,direction at any time.Position detection device using rotor position sensor (photoelectric encoder or rotating transformer,etc.).Capsules load detection device can ac motor wind generator use a variety of forms such as position,pressure,to measure and calculate in advance,the elevator load given proper direction and the size of the moment,can switch output,analog (voltage) and frequency (hf anti- jamming is strong,can remote transmission),etc.The feedback signal is compared with the given signal,computing,according to the predetermined control mode control,can get better than that of the other performance of the drive system.

The diagram of three-phase asynchronous motor

In the industrial field, three-phase asynchronous motor because of its easy to use, high efficiency, was welcomed by many factories. A lot of people for this device, also began to have a preliminary understanding. And this kind of three-phase asynchronous motor, but also the emergence of a three-phase asynchronous motor diagram. A lot of people don't know such figure how what kind of role, also some people don't understand. Really want to say to the role of, or more. www.facebook.com/dongfeng.motor First: to know the motor vehicle spare parts working principle of three-phase asynchronous motor The three-phase asynchronous motor, chart for some people who do not understand, is very confused. In fact, as long as people will look at the picture, through this picture, can know what is the working principle of three-phase asynchronous motor.

 And through such a working principle, can also learn about the three phase asynchronous motor is used in what areas. The second: know how to work through the three-phase asynchronous motor Through such a figure, also can let people know how to let the three-phase asynchronous motor, according to their own needs. So that the three-phase asynchronous motor can also according to their needs, to work and production. Third: learn how to asynchronous motor for three-phase asynchronous motor operation Most people for three-phase asynchronous motor is not very familiar with, although know the principle, but still don't know how to operate. However, map can help people to solve this problem, it can let people know that if the operation for three-phase asynchronous motor, so as to avoid because of not operating and the embarrassment. This is the diagram of three-phase asynchronous motor. In addition, such as three phase asynchronous motor wiring diagram, can bring people a lot of useful information, help people better understand the operation of the three-phase asynchronous motor, etc.
