P0480 code Condenser fan motor is hot to touch. It will run for a few minutes when AC is turned on. Could it b?
- It sounds like the fan motor has gone south on you. Shouldn't be too horribly priced--I'd say anywhere from $50-$300.s
for a wind turbine can i use an ac motor to charge a battery system,?
- AC motors use the AC power to create the magnetic fields of fixed and rotating parts so there is no field unless AC is supplied. The device you need to use is an alternator, as in a car, which is simpler and more reliable than the old DC generators with their commutators. The alternator makes AC power and diodes in the body convert it to DC.s
Along with coils in a 7.5 HP AC motor, Are magnets are used?
- Unlikely, most ac motors are induction motors. If your 7.5HP motor is 3 phase, which is most likely as it seems large for single phase, the rotor will be what's called squirrel cage. This is aluminum bars made into a cage. The rotating magnetic field in the stator induces a current into the rotor, the same way a transformer does but the resulting magnetic field produced is opposite to that of the stator causing the rotation. Smaller single phase motors may contain windings and there are a number of different types of single phase motors. Larger 3 phase motor may be wound rotor so that some resistances can be added through slip rings for starting or speed control. There is a type of ac motor called synchronous motor. The rotor is powered by dc and is, in effect, a large magnet but this type of motor is not self starting and uses some other method to get up to speed before the dc is applied.s
The difference and advantage between DC motor and AC motor
- DC motor：Advantages: 1., you can achieve a smooth and economical speed adjustment;2. does not require the coordination of other equipment, as long as the input or excitation voltage, currents
Who knows the main difference between DC motor and AC motor, I hope to say a little more simple, thank you
- DC characteristic:(1) good speed control performance. The so-called "speed performance" refers to the motor in a certain load conditions, according to the needs of artificially change the speed of the motor. The DC motor can achieve uniform and smooth stepless speed regulation under heavy load condition, and the speed range is wide. (two) starting torque is large. The speed regulation can be realized uniformly and economically. Therefore, all the machines which start or require uniform speed regulation under heavy load, such as large reversible rolling mills, winches, electric locomotives, trams, etc., are all driven by DC motors and motors.Communication characteristics:The AC motor has higher working efficiency, no smoke and dust, no pollution to the environment and little noise. Because of its series of advantages, it is widely used in industry and agriculture, transportation, national defence, commerce and home appliance, medical equipment and so on.s
How did the electric motor change the world?
- You are using the term electric motor too loosely because there is the DC type and AC. Also Faraday's motor was a proof of concept, and was not a practical design to use. The modern DC motor with a commutator got its design ideas from Thomas Davenport's motor. The modern AC induction motor is the design of Tesla. The electric motors of both AC and DC changed the world by replacing the combustion engine in manufacturing applications with proven reliability and ease of speed and torque control (DC motors initially, since speed and torque control of AC motors was hard to figure out back then). Electric motors (mostly AC induction) are used in applications such as plastic injection molding machines, milling and lathe machines, compressors, forge presses, pumps, cranes, locomotives, conveyor belts, oil well pump jacks, hammer mills, ball mills, sawmills, printing presses, HVAC systems, etc. Basically, your average Joe would not know that electric motors greatly outnumber combustion engines and that electric motors are what make the majority of the products we buy. I hope you write a good essay so you can educate people that the combustion engine is the underdog, not the electric motor which has more market share. :)s
what happens when an electric motor is overloaded?
- When an electric motor is running nomally, it will be generating electricity as well. This generated electricity will oppose the power supply to the motor, and thus decrease the current being consumed by the motor. This is known as Back EMF (Electro Motive Force). If the motor is then overloaded it will slow down. This will decrease the ammount of Back EMF being generated, and so the current will increase dramatically. This will cause overheating, depending on how much the motor is overloaded. If it is stalled, it may well catch fire. Air cooling the motor, using perhaps a fan, will help the situation.s
Why is the capacitance of a single-phase motor adjustable speed?
- Compared with the inductance governor, the capacitor governor has the advantages of small size, easy installation and long service life, especially if it does not consume power. In addition, the use of capacitor speed regulation can also improve the power factor of the grid. Therefore, the use of capacitive speed of small single-phase motor is also more common.s
