Note:
In order to prevent electric shock, the motor and frequency converter must be
grounded before use.
• Do not install the incoming capacitor or surge suppressor, radio noise filter
to the output of the frequency converter. This will lead to the failure of the
frequency converter or the damage of the capacitor and surge suppressor. If any
of the above equipment has been installed, please remove it immediately. When
it is necessary to set a non fuse circuit breaker at the output end, please
consult the manufacturer for the selection of non fuse circuit breaker.
• With regard to electromagnetic wave interference, the input / output (main
circuit) of the frequency converter contains high-frequency components, which
may interfere with the communication equipment near the frequency converter
(such as AM radio). Therefore, EMC filters are installed to minimize
interference.
• For details of peripheral devices, please refer to the user manual of each
option and peripheral device.
• PM motor cannot operate on power frequency power supply.
• Because PM motor is a motor with built-in permanent magnet, even when the
power supply of frequency converter is disconnected, as long as the motor is
still rotating, high voltage will be generated at the motor terminal. When the
output switch is closed, turn on the power supply of the frequency converter
- Q: how do i work out the voltage output of the second winding on a transformer if i know the Primary voltage is 35v and the first winding has 355 windings and the second winding has 4500 how do you do this ?thanks
- Assuming that the transformer is designed for a primary voltage of 35 or more, then you can simply multiply the applied primary voltage (up to the design limit) by the turns ratio and this will give you the output voltage. In this case: output voltage 35 x 4500/355 444.
- Q: Any help much appreciated here, I cannot understand the following formulas at all. If there is anyone who can please explain in very SIMPLE words I would be very grateful. My exam is next week and I am still stumped on the following.VP/VS NP/NS IS/IP ok this bit I understand, but then here are the QAs that don't make sense to me:Q1) A single phase transformer has 1250 primary turns and 200 secondary turns. Primary V I are 230V and 3A. What are the secondary V I?A) 1250/200 230/vs transpose too: VS 200 X 230/1250 36.8V Why has it been turned upside down?230/36.8 Is/3transpose too: Is 3 X 230/36.8 18.75A Why??The following Q I am even more stuck withQ2) Single phase transformer has a rating of 300/230V, 15KVA. What is the full load of primary and secondary?A)S VI Where did S come from?!Ip 1500/3300 4.55A KVA - is this taken as the V? Not I? Is that why Is 1500/230 65.22A it has been reversed? I'm very confused, please can someone help explain this process to me?

- Q: Want to use in the air compressor, I do not know it?
- Can not. Because the main role of transformer oil insulation is not lubrication. Its water absorption is strong.
- Q: does anybody know what Transformers 2: Revenge of the Fallen is going to be about? Like what is the whole plot, or storyline?
- The battle for Earth has ended but the battle for the universe has just begun. After returning to Cybertron, Starscream assumes command of the Decepticons, and has decided to return to Earth with force. The Autobots believing that peace was possible finds out that Megatron's dead body has been stolen from the US Military by Skorpinox and revives him using his own spark. Now Megatron is back seeking revenge and with Starscream and more Decepticon reinforcements on the way, the Autobots with reinforcements of their own, may have more to deal with then meets the eye. I'd take that with a pinch of salt though as it's probably fan invented.
- Q: Transformer Lightning
- Dry coil internal coil will burst open, so that the transformer outside the four sides of the shell will be bulging. Cylinders on the porcelain will burn black, porcelain will be black and cracked. The line breaker is tripped.
- Q: An AC adapter for a telephone answering machine uses a transformer to reduce the line voltage of 120 V to a voltage of 8.00 V. The RMS current delivered to the answering machine is 570 mA. If the primary (input) coil of the transformer has 600 turns, then how many turns are there on the secondary (output) coil?What is the power drawn from the electric outlet, if the transformer is assumed to be ideal?What is the power drawn by the transformer, if 13.5 percent of the input power is dissipated as heat in the coils and in the iron core of the transformer?
- Hello Samantha, in case of ideal transformer the power at the out put would be the same as that in the input. To get the power we need voltage and current. Voltage at the out put is 8 V and current is 570 mA. Hence power consumed by the machine is 4.560 W. So the power drawn in case of ideal transformer will be the same as 4.560 W If the efficiency of the transformer is 86.5% (100-13.5) then the input power will be 5.27 W (approx) To get the number of turns in the secondary let us use Ns/Np Vs/Vp Hence Ns 600*8/120 40 turns.
- Q: assuming a delta connected single phase transformers , why is the neutral side is connected to ground, my question is will the current be shunted to ground since it has a low resistance??? please explain
- In electric distribution structures transformers are available countless sizes. Heavy ones are generally located on the floor with a concrete pad located under it to furnish help. those pad fastened transformers are risk-free against touch with the regularly occurring public generally with a fence. Pole fastened transformers are lighter and can be accurately located immediately on the skill pole. i don't comprehend of any floor fastened transformers different than for transformers located in vaults while the distribution strains are underground. yet those additionally desire some form of pad under them.
- Q: I just purchased a little halogen spotlight lamp with an Class II transformer that converts 110v-120V to 11.5V. When I put my ears about a 12 inches from the transformer near the wall outlet, I hear a little buzzing or humming noise. Is this normal or is there something wrong?
- A transformer creates a magnetic field that varies at the rate of the line voltage (60 or 50 cycles per second). If there is something in that field that is magnetic, it will be pushed back and forth at that rate, and if it can move, it will create a buzzing sound. Almost all transformers produce a little bit of sound, because the core is made up of layers of magnetic material that are glued together. It's not anything to worry about, just a nuisance.
- Q: What is the transformer absorption ratio (R60 / R15)
- Generally, the absorption ratio should be greater than or equal to 1.3 as the absorption ratio is acceptable.
- Q: explain the role of both types of transformers in getting electric energy from an electric power plant (coal-fired, natural gas or nuclear) to our homes.
- A step UP transformer is used to boost the VOLTAGE, as by doing so the CURRENT is reduced by the same factor, e.g. boost voltage by 100 x, reduces current to 1/100th. By reducing current, power losses due to the transmission line RESISTANCE is very significantly reduced, especially in long run distances between consumers and the generating plant. The formula I^2*R is power, and the square of (say) 100A is 10,000, whereas if the current were reduced by 100 fold as above, the current becomes 1A., so you can see the difference! 1^2 1, versus 100^2 10,000. But the voltage is too high for consumer use, So a step DOWN transformer is used to change the voltage down to the required domestic voltage. The ratio of this transformer can easily be adjusted to allow for the minute power lost in the high voltage lines. The overall effect is very much less power lost in heating the connecting wires in the transmission lines, so much more power available to consumers.
