As with SPI, XGATE can be bit operation through direct counterpart or general asynchronous receiver- transmitter to control software SCI. This is similar to the original function of synchronous communication, of course, critical bit clock edges water pump price are not the same. XGATE coding in the asynchronous serial communication electric motor parts is strictly limit (maximum baud rate usually 19, synchronous generator 200 b/s). Under the condition of maximum response time must keep the baud rate of 20% and 2% of the total, namely every 10.4 mu s for generator price each sample or set up one more time. Although the processing time is allowed to change, but under the baud rate of 19, 200 b/s is not in the sending and receiving the correct 8 bits of data on conflict. XGATE coding send SCI data needs to be generated by a timer compare two fixed duration: one is a cycle;

The other is a breakpoint detection time, usually ac synchronous generator for many bits cycle time. One in the transport Electric motor process is very short, only need ac induction motor to set up lamination a pointer to electric motor low rpm the output state and change. Receive data requirements with a cycle time sampling was carried out on the middle passage, and this will interrupt apart before, like entered another XGATE interrupt, disrupt rate doubled. In addition, this program is very short, in the worst case between interrupt (send/receive, 19 200 baud rate for the b/s) of the interval is 26 mu s; Under the influence of the XGATE clock program (19 200 baud rate for the b/s), SCI before send and receive data, allowing a program about 36 mu s (+ 10.4 mu s allow delay. 26). This is a when XGATE program to join, how to meet the maximum delay and allows other applications to perform good example.

High voltage motor stator coil damage problem Electrical engineers

General electrical engineer pointed out that the long-term operating experience and motor stator

winding accident phenomenon indicates that the generator and high voltage motor stator coil corrosion damage phenomenon is quite common,seriously affect the safe operation and service life of the motor.A,corrosion characteristics and parts of motor stator coil From the high voltage motor stator winding coil main insulation breakdown phenomenon,the main coil corrosion damage of the insulation can be roughly divided into two classes: class starts to coil outside the main insulation inner corrosion damage,often referred to as corrosion;Another kind began to coil internal insulation outside corrosion,commonly referred to as internal corrosion.1.1 main coil insulation outside corrosion damage (1) motor stator winding end inside the stator core and coil vibration,the primary coil insulation corrosion damage.This is the most common corrosion damage accident is also one of the most serious phenomenon.Cause this is the main reason of the corrosion damage,the motor in operation,because of its department of winding vibration under the action of electromagnetic force,the coil in the stator core groove end fixed not firm,article slot wedge,the line between layers of cushion,loose end interval block and tied the rope off,coil and lashing and friction within the interval between block,anticorona lacquer semiconductor corona corrosion damage,resulting in slot and end coil main insulation breakdown.

(2) the stator core wear corrosion of the internal magnetic materials.This kind of situation is mainly due to the maintenance process without careful cleaning and purging of the stator winding,causing the windings cracks and other corner place left some tiny

magnetic sundry,when the motor running magnetic debris was adsorbed on the surface coil insulation Lord,under the action of electromagnetic induction and electromagnetic force,magnetic impurities in rotation movement,grinding main coil insulation to drill a hole.(3) of the stator coil corrosion of

oil.At present,a large generator and high voltage motor bearing shell are widespread leak

phenomenon,thus the motor coil for burning oil corrosion accidents are quite common.Parts of the

basic focus of this kind of failure at the end of motor stator slot,winding and winding nose

leads.Are attached to the coil is characterized by the oil,to dissolve erosion effect to the main

coil insulation,main insulation and conductor is layered whole coil insulation strength is

reduced,after long time running and stator winding short circuit,grounding short circuit fault,etc. (4) the stator core silicon steel sheet of corrosion wear of the insulation.If in the process of being connected in the stator iron core,silicon steel sheet laminated,irregular or stator core ventilation channel and the end pressure refers to fixed installation,or damage to the stator core in the repair,will cause the vibration occurs when the motor running,wear insulating,eventually resulted in the breakdown of the main insulation of wire coil.1.2 coil corrosion Multiple accident statistics and fault coil autopsy results show that the coil internal corrosion is more serious.

Corrosion inside the large coil anatomic analysis showed that the corrosion is generally from insulation and conductors in the air gap between the air bubbles,coil straight line and the end of the R Angle,coil

lead off line welding etc.Corrosion phenomena within the first coil internal insulation to bleach and

gradually expand,then burning insulation form hole and a large number of green powder,so as to

accelerate and main corrosion damage of the insulation between wire strands,until the main insulation breakdown.In addition,the high temperature caused by the thermal aging is also an important factor to the internal corrosion.Second,the coil reason analysis of internal and external corrosion Motor

stator coil of the internal and external corrosion reasons,mainly due to the main coil insulation in

the motor running,long-term in electromagnetic vibration,high temperature and high voltage under the action of three kinds of factors and vibration wear,corona corrosion and thermal insulation

aging,make whole coil insulation shell,layered,burning,wear and dielectric strength reduce wait for a phenomenon,resulting in insulation breakdown of failure.Electromagnetic vibration wear corrosion (see electrical engineer) In the operation of the motor in produce all kinds of mechanical vibration,wear out coil insulation,corrosion is one of the main electromagnetic vibration on the motor end winding and the influence of notches.

If the stator core installation quality is bad,bad winding end binding process,make the coil in the groove by fixed bad,produce great vibration amplitude,article water pump interlayer pad and temperature measuring element pads in the lower level to HuiCuan move between coil and wear on the lower layer coil,the coil main insulation damage.Is more serious is that,if in the operation of the coil wire through the current 2 times frequency electromagnetic vibration,will not only make the coil and iron core and winding end interval block vibration,make the main insulation surface wear,but also can make the wire with the main insulation between the friction between interturn,shares of the wire vibration,causing wire

interturn,loose,short circuit,break between the shares.At the same time,the additional loss and the

temperature rise in short circuit,will accelerate local main insulation ageing,reduce the dielectric strength,even under normal working voltage insulation breakdown caused by failure.Therefore,the electromagnetic vibration is caused by coil outside the main insulation 8500w gasoline generatorcorrosion and the main cause of the corrosion damage.

The vibration and noise of the motor

Normal operation of motor is stable equilibrium, in case of severe vibration shows a malfunction or abnormal noise. Light will affect the normal operation, shorten the life of equipment; Or burning motor, serious will endanger the whole pump room safe. Therefore, once appear, fault, shall be immediately cut off the power and stop running, timely find out the analysis of the cause of the ac electric motor problem, in order to avoid the situation further, causing a greater loss. Must find out the cause of the problem and the correct processing, can continue to run. 

(1) the cause of motor vibration for many reasons, the cause and the treatment methods such as the common motor vibration (1) adverse or lower quality check, calibration installation quality (2) bearing corrosion or wear adjust or replace the bearing (3) the rotor winding is impaired, asymmetric magnetic rotor winding (4) the loose coupling, different maintenance and calibration shaft for the school (2) the phenomenon of abnormal noise of the motor and the reasons are: (1) if there is a huge buzz, said current excess, this is due to overload or imbalance of three phase current, sometimes caused by power frequency instantly change; (2) if a hissing sound, it is caused by relaxation of silicon steel sheet; (3) if there is the voice of "guru, guru", is a bearing frame in damage, noise in operation; (4) when the bearing wear, motor air gap change, is not even touch between rotor and stator grinding sound, and with an exception of anxious burnt smell and smoke; 5. If two phase short circuit and arc has a huge sound, and issue a special caramel flavour. In addition, the monitoring of motor temperature is extremely important. According to the type of motor and winding insulation materials, used in the operation should not exceed one of the biggest manufacturers of winding and iron core allows the temperature and the temperature rise, the maximum allowable temperature and maximum permissible temperature rise is the relationship between: three phase induction motor maximum allowable temperature = maximum permissible www.facebook.com/dongfeng.motor temperature rise + ambient air temperature.
