7.5kw Brushless AC Alternator Stc Price Stamford New Design

Generator characteristics:
1.Large Short circuit capacityimprove the ability to start the motor directly.
2. Integral casting machine body improves the concentricity and mechanical strength.
3. Convenient wiringmakes itmoreeasier to change the output voltage
4.Better voltage regulator, so that the generator output voltage is basically stable unchanged.
5.The designof aviation conductive ring make generator runmore smoothly.
6.2/3concentric winding distribution way, let the generator voltage waveform distortion is smaller.
7.Simple wiringmake windings and components lead wiring more reasonable and smooth.
8.A reasonable production process and a lot of detail designs make the generator has longer service life.
Engine casingcharacteristics
1.One-piece frame castingincrease the mechanical strength, and in the process to ensure good concentricity to improve the machining accuracy.(The ST STC casingis divided into drive end cover, the body and the non drive end cover assembly, the three partscan not be processed at the same time, must be processed separately, thus, when machining is assembled, machining errors and assembly errors can be generated.The three can not reach concentric, thusgenerator in the process of running easily mechanical resonance, Reduced service life, Increase the rate of voltage waveform distortion and electromagnetic noise.)
2.Increase the thickness of the body casting, Make the generator run more smoothly, better heat dissipation effect.(Such as the ST/STC generator chassis and rear end cover is easy to rupture, Some have not yet delivered to the customer and in transit has been broken, And some to the customer did not use a period of time also broke up.
3. Use TH200 brand of cast iron casting base,More resistant to corrosionand able to operate in harsh environmental conditions.(Such as the Stamford generator for thin plate forming, running in corrosion resistance and harshenvironment,after a period of time the shell is easy to corrode a lot of holes,Causes the damage of winding and core components are exposed.Conducting ringcharacteristics:
1. Aviation electric conduction ring make running more stable,don't worry about the Carbon brushpoorcontactany more, or the carbon brush and the copper ring is worn too fast.(such asthe carbon brush and the copper ring of ST/STC generator often bad contact and shift,cause the generator does not generate electricity, the carbon brush and the copper ring is worn too fast, not for a whileit has to be replaced carbon brush or copper ring.)
2.Conductive ring connectorwith the lotus type copper core connector, make maintenance more convenient and replacementmorefaster.(The ST/STC to replace the copper ring,firstneedto dismantle the carbon rod and bearing cover, and second need to take non drive end capapart, then remove bearing, at this time canremove the copper ring, the procedure is complex, replace is very troublesome. if the exciter armatureof brush-lessgeneratorfailure, dismantling is very troublesome, And needs special tools and professional maintenance personnel toreplaced.
3.Sealed conductive ring,don't have to watch out for the oil or water droplets.(If the ST/STC generator hasa little grease adhered to the above, the copper ring will produce a layer of insulation isolation, so that the generator can not generate excitation voltage without generating electricity.)
Winding characteristics:
1. The concentric 2/3 winding distribution reduces voltage waveform distortion and improves power quality.
2.Bare part of the winding spray paint,Can effectively prevent dew, corona, anti-corrosion, at the same time can improve the winding mechanical strength.
Voltage regulator characteristic:
1.Binary dual path controlled voltage regulator,it makesthe generator run more smoothly,no-load and load voltage variation is not more than 2%,Cold and hot state voltage regulation rate is less than 3%.
2.The fixturesof Shockproof regulatorincrease the earthquake resistance of the regulator.No longer have to worry about the solder joints due to vibration and damage.
Fan characteristics:
1. The designof centrifugal fan haslargerair volume,better heat dissipation, so the winding insulation is durable.
2. The cast -aluminumthermal sleeve type of fan bracket, No longer have to worry about using a long fan out of rotation.
3.Fan and fan bracket separate designs make the replacement fan more simple.
Bearing characteristic:
Using double sealed bearing, make the bearing service lifelonger, run more quiet. No longer like open bearings that need to add grease regularly. Such as ST/STC generators are open bearings, this bearing is easy to grease, bearing beads damage caused by dry millin the bearing room.
Process details:
1. All parts contacted with the wire are wrapped or isolated with specially designed insulation devices.
2. All terminals with insert type, the two terminals inserted into the guiding wire in the insulating sheath,the other two stuck copper wire,so that the end is not easy to loose from the lead wire and lead wire is not easily broken due to vibration.
3. The markof terminals is distinct, so that each line can be found in the corresponding position on the wiring diagram,and not as connecting the wrong wire damage the motor or component.
