In the network packets of data flow can be respectively in 2, 3, or 4 layer for identification. Each layer will provide more detailed information about the data flow. In the second layer, each packet of data flow through the motor electric source site and destination MAC address is identified. Within the broadcast domain, layer 2 switching function is limited, this is because the source and destination MAC address is only account for a packet of information in a rough. Layer 2 switches can provide cheap and high bandwidth Internet connection, but they are unable to provide necessary control data flow of the trunk. In the third layer, the data flow through the source and destination network IP address is identified, the ability to control the data flow is limited to the source, ANP gost motor destination address.

 If a client is using multiple applications on the same server at the same time, the layer 3 information is not detailed description to each application flow, which makes it impossible to identify the different data streams, more can't one by one for each data flow to implement different control rules. The fourth floor is the transport layer of the OSI model. It is responsible for coordination of network communication between the source and destination system. TCP (transmission control protocol) and UDP (user datagram protocol) are located in the fourth floor. In the fourth layer, each packet contains can be used to identify only send the package information application. Can do this because the TCP and UDP header generator set contains "port", the port can determine each package contains application protocols. The port number of the layer 4 header information and the layer 3 header source - goal combination can realize accurate control of real information. Specific application dialogue can flow control between the client and the server, if the switching router is a full-featured, is all this work can be done at wire speed.

 Repeaters to go in and out In and out of Repeaters is the interface circuit between the trunk and switching network, is used to switch trunk connections. Its features and circuit and switching system used in the system and trunk signal way has a close relationship between innings. To simulate relay interface unit (ATU), its role is to realize the simulation of the trunk and exchange network interface, basic functions in general are: sending and receiving said trunk status (such as idle, occupy, reply, release, etc.) of the line signal. Forward to receive on behalf of the called number of register signal. Supply the power supply and signal. Provide the received signal to control equipment. For the simplest case, a switch relay through solid line trunk with another switch connection, and USES the subscriber loop signal, then the simulation of the repeater function and equivalent to a "phone". If other more complex signal method, the repeater should implement the corresponding voice, signal transmission and control function.

Digital trunk interface unit (DTU) role is to realize the digital trunk and the interface between the digital switching network, it was related by PCM timeslot transmission trunk signaling, complete is similar to the basic function of the simulation should bear repeater. But as a result of the digital trunk transmission way of PCM digital signal, therefore it has some special issues of digital communication, such as frame synchronization, the clock recovery, type exchange, signaling insertion and extraction and so on, which to solve the signal transmission, synchronization and signaling with three aspects of the connection 3 phase induction motor problem. The basic function of digital acmotor2.blogspot.com ac motor relay interface unit including the frame and the complex frame synchronization code generation, frame, even zero suppression, type transformation, alarm processing, clock recovery, frame synchronization search and inter-office signaling insertion and extraction etc., like permanent magnet motor BORSCHT simulated user circuit, also the above eight kinds of function of digital relay unit can be summarized as GAZPACHO.

ZC25B - 4 type insulation resistance meter test three-phase insulation. The insulation ac electric motor resistance tests measuring leakage current between the two wires. So need to put the two clip sandwiched between two wire line core. (shaking table on the grounding wire don't let it empty) wire core yellow green, A and B are measured relative phase of the insulation resistance between A to B. Red line core green B and C, the Induction motor relative phase between measurement is B to C is insulation resistance. The wire core is A and C, the measurement of the insulation resistance is A relative phase between the C. Wire core A and N, insulation resistance measurement is A relatively is zero. A line core with PE, the insulation resistance measurement is A relatively. And so on. 1 kv under low pressure, the test ZC23 or 25, two clip clamp respectively clean two conductor, from slow to quick turn the crank, about 120 r/min, maintain uniform, pointer corresponding calibration is insulation resistance magnet generator value. Such as refers to 200, is 200 ohms.

The similarities of stepping drive way

If readers are smart,or very careful when practice,maybe you will note that single polar stepper motor and bipolar stepper motor on the stepper drive mode is very similar.As described above the single polarity of stepper motor step way form,for example,by exchanging electricalmotor1.blogspot.com the positions of the column and column C B,all the "tong" replace with "+",then in the lead with status to "+" in another column of the same winding up ".",will see and bipolar stepper motor in the same format on the form,only motor to the electric motors 12 voltopposite.This shows that any logic control single polar stepper motor can also be

used to drive a bipolar stepper motor.Pay attention to is the logic,rather than drive circuit.Bipolar

magnetic generator stepper motor windings need H bridge circuit,and the single polarity stepper motor only need a simple transistor switch.Do in single polar stepper motor control and switch between single phase asynchronous motorbipolar stepper motor,the only change is the exchange of B and C need logic output.

Motor points for attention

(1) before disassembly,should surface dust with compressed magnet generator air

blowing off the motor,and scraped clean surface dirt.2 choose motor working place,the disintegration of the clean up the scene environment.(3) familiar with acmotor2.blogspot.com the

motor structure characteristics and maintenance technical requirements.(4) ready to collapse the

required tools and equipment (including special tools).5] in 220v electric motor

order to further understand the defects of the motor running,conditional when can do an inspection test before disassembly.For this,turn motor with load test,the detailed check parts,such as temperature,sound,vibration motor,and test the voltage,current,speed,etc.,and then disconnect the load,do a no-load check test,no-load loss and no-load current is measured and recorded.
