Siemens 1PQ Series AC Motor

Q: I should do this with a AVR microcontroller circuit: The motor speed will follow frequency pretty close- slippage that is related to load You have to vary voltage directly to frequency or it will use too much current at low speeds and won't have torque at higher speeds. Variable frequency drives do this automatically, that is why they cost so much.

Q: my uncle had a GENERAL ELECTRIC/MARS Motor mod: 5KC49WG507X and I don't know what it is...can any one help explain this to me?: To protect motor being burnt even caught fire by overheated due to overload or non stop running. It cut away input power feeds to the coil while it reaches its preset temperature.

Q: AC Repair person said I have oil leaking from fan motor and should have replaced. Even though it still works. Show me how hot it got.: it incredibly is the crankshaft rear oil seal. as a fashion to change this, it incredibly is engine or transmission out, Flywheel off, and on occasion, the sump and rear considerable bearing cap off aswell. no longer a 5 minute job. you'll want extreme lifting kit, and a heat workshop.

Q: I am converting my '79 VW rabbit from ac to non-ac.Where do I find the bracket that holds the alternator low on the block.: Check first with the auto-parts dept.at the dealership. They are fairly knowledgeable as to whether that is possible. Otherwise ask the service manager if that is possible to do. They may have a parts car out back of the dealership and you could get a used bracket there. Otherwise check out autosalvage yards for a 79 non ac car for the bracket.

Q: What will happen if i supply ac current To a dc motor?: DC autos function in basic terms whilst dc modern is given.If we alter the polarity shaft will run in opposite direction.whilst u provide Alternating modern, created magnetic field retains it in a null factor ensuing the coil to get heated up and burned.

Q: What are the advantages and disadvantages of AC and DC motors?: The DC motor is easier to control than the AC motor. It can be applied to a wide range of speed regulation. It can be used in power braking, but it is more complex and more complicated than the maintenance of AC motors.

Q: The Pump Motor Hums when the switch is turned on. Remove the pump and the impeller turns freely.: Impeller shaft may be bent.

Q: I need to know if it is possible to control the speed of a 220 volt ac motor (from a washing machine so I assume it is 3 phase) but the system has to be compatible with the arduino. So if it is please let me know how. Thanks: that would be very hard since arduino is low voltage dc and your motor is very high voltage ac so first off the voltages are incompatible maybe and ac-dc relay this could help you forum.arduino /index.php/topic,...

Q: The difference between three-phase AC synchronous motor and three-phase AC asynchronous motor: Asynchronous motor is stator into alternating current, to produce a rotating magnetic field, and the rotor is produced by induction and magnetic field, so that the two magnetic field, so that the rotor rotates the rotating magnetic field of stator and rotor. The stator rotating magnetic field than a slow slip, not synchronous so called asynchronous machine.The rotor of a synchronous motor is a constant magnetic field which is added by the man to the direct current, so that the rotor is synchronized with the rotating magnetic field of the stator, and then the synchronous motor is called synchronous motorStructure and principle

Q: Hi friends,Can any one help me to find the electric motor with 40HP and 500RPM for my project. RPM upto max.1000RPM is acceptable. Please help me. The motor should be available in INDIA. Thanks in advance :): AC motors in that HP range are usually available as three phase, at RPM's of 1200, 1800, 3600. 1800 RPM is standard speed, so that will be the cheapest. To get down to 500 RPM, you have several options: Reduce the speed using pulley ratios. This is the cheapest if your application will accept it. Use a bolt on gear reducer. This is the best and most popular solution if you only need one output speed. Both the solutions above give you the advantage of reducing the motor HP to around 15 HP since you are reducing the speed but tripling the torque to that of above 40 HP. At 15 HP, you can switch to single phase if you have too, but stick with 3 phase if you can because they are much more efficient motors. Other options which give you variable output speed are an AC motor speed control (very expensive), or switch to a DC motor and controller (very, very expensive, if they even make them that big.) Search Baldor, Emerson, Lincoln or Grainger for motors. See Emerson, Grove or Boston for gear reducers, pulleys. See Gates for belts.
