- Q:Why in general larger aircraft make use of both AC and DC electrical systems.?
- AC motors and controls can be made smaller and lighter, especially when driven at 120V and 400 hz. Almost all, if not all, systems that are intended for normal use with normal power will be AC. DC, on the other hand, is the old stand-by when down to just battery power. If a pilot arrives at a dead airplane, with no external power (AC), how will he get the thing running if it requires A/C? With one or two batteries, one DC fuel boost pump, a DC starter on the APU, DC fire detection and DC fire fighting systems, he can safely get the airplane up and running, and if a fire breaks out during the process, he can fight the fire. If there is a loss of all AC generators, then there needs to be some DC powered stuff from the battery (basic flight instruments, basic lighting, etc.) to allow continued flight while attempts are made to restore the AC. On the Boeings, the fallback really important stuff will be found on the hot battery bus, battery bus, DC transfer bus, and standby DC bus. The Airbus probably does the same thing using different names.
- Q:How did they convert ac to dc current on electric train transformer when they didnt have transistors then?
- Electric Train Transformer
- Q:Hey I understand the basic concepts of a dc motor/ alternator and want to know how many turns and such can anyone help I am going to try to make it charge some batteries by wind
- An alternator is not a DC motor - it is wound to produce alternating current (thus the name) which is rectified by diodes on the case to make DC. Winding a DC motor/generator is not a simple task requiring multiple segments and a commutator to collect the segments in detail. You would be much better off just buying one, perhaps used, than spending your time trying to build something with reliable bearings and speed.
- Q:motor control
- Electrical drives are electrical motor controls that control motor speed. For many years, most electrical drives used DC motors, but AC motor drives have now become the dominant type. The most common AC motor speed controls are variable frequency drives (VFDs) that control the speed of 3-phase induction motors. In the most common type of VFD, mains power is rectified to provide DC power. The DC power is then converted to 3-phase AC power using electronic switching circuits in an inverter configuration. The inverter controls both the frequency and the voltage supplied to the motor using pulse width modulation to control the voltage. The voltage supplied to the motor must be proportional to the frequency. To operate at half of normal speed, the motor must receive half of the mains frequency and half of the mains voltage. The motor can produce its full rated torque at reduced speed, but the power is reduced because power is proportional to torque multiplied by speed. Electrical drives are electronic power conversion devices. The electronic circuits operate at 3-phase mains voltage and carry the full motor current. Thus their power rating is the same as the motor power rating. Their efficiency is typically 95% to 98%, but that means they must dissipate 2% to 3% of the motor power as heat which can be quite a lot of heat.
- Q:What about the capacitance of the AC motor?
- In general, the starting capacitor of single-phase AC motor can not be chosen too large, the starting torque angle will deviate from the maximum value, and the secondary winding current consumption will increase. The motor is too long for the motor to run for a long time!
- Q:Why don't AC motors use commutators?
- Because the direct current motor changes the current direction through the commutator, the coil continues to rotateThe alternating current is always changing direction, there is no need to use the commutatorThe difference between an engine and an electric motor is that there is no power supply on the engine connected to the motor, and the motor is connected to the power supply, but it may not have no other electrical appliance
- Q:easy to understand explanation would be nice
- This is not so easy to explain. If you looked on the web for how ac motors work and also for DC motors, you could almost certainly find some animations that would be understandable. Generally an DC motor uses commutators to create an offset in the magnetic fields created in the rotor. An AC motor uses a capacitor to slightly delay the AC waveform, and in that way, offset the magnetic field produced in the rotor. but without actually seeing some sort of diagrams, this will not make much sense.
- Q:Does anyone know of any websites to do this? I have an old 110v AC motor from an old vacuum.
- Actually, almost any AC motor can be turned into a generator. Your AC motor will produce an output aafter you excite it with a quick hit with a vattery. Once you have AC, you can rectify it.
- Q:AC servo motors generally choose synchronous or asynchronous?
- It seems that there are asynchronous servo motors, but the synchronous servo motors are used in the market.
