Why synchronous motor is called synchronous capacitors?
A synchronous motor can operate as either a Generator or a Motor.When a synchronous motor has current applied to the windings on its rotor and the stator is energized with say a 50hz line supply (with little or no physical load) then the exact amount of excitation provided by the rotor can determine whether the stator displays inductive or capacitive properties.If the rotor is under excited (too Little rotor current) the Synchronous Motor will behave as an Inductor, however if the rotor is over excited then the Synchronous Motor will behave like a Capacitor.Hope this helps

What happen if 3 phase supply given to rotor instead of stator?
If the motor was running in a clockwise rotation it will continue to run in a clockwise rotation. Single phase motors have to be built to allow for rotation reversal and then tap changes are made at the motor terminal box to reverse the motor.
What is synchronus capacitor?
A synchronous condenser (also known as a synchronous capacitor or synchronous compensator) is a DC-excited synchronous computer (large rotating generators) whose shaft is now not connected to any using equipment.
Difference between synchronous generator and synchronous motor?
ASYNCHRONOUS is a mode whereby events happens irregardless of control. SYNCHRONOUS are this same events but controlled by a timing and/or control
Which motor is used for domestic purpose?
In the home induction motors are used the most, because they are reliable and last a long time. They are the favoured type for refrigerators and washing machines. The exception is portable appliances like vacuum cleaners and hand tools, which use commutator motors, basically the same as DC motors. These are preferred for their better power to weight ratio, even though they are noisy and require more maintenance such as replacement brushes and regular commutator cleaning. Some types of electric clock use small synchronous motors that have permanent magnets built into the rotor. These motors produce only a couple of watts of mechanical power at the most.
What is the difference between asynchronous and synchronous motors?
Synchronous AC motors run at a speed fixed by the input line frequency. Typically 60 Hz in the USA. Run a clock with the sync motor from the USA in England and it runs slow because they use 50Hz. Asynchronous motors run at whatever free-run speed they feel like, and slow under load. A DC wound hand-drill is such a motor, runs pretty fast till you start drilling, then it slows down. A synchronous motor will develop maximum power at its' designed speed, try to slow it down and it puts out more torque. Slow it down by overload, it doesn't create more power, it just creates more heat. An Async motor creates highest torque at stall speed, least torque as it approaches maximum speed.
What is a rotor cap?
A rotor cap is a protective cover used in various mechanical and electrical applications, particularly in rotary devices like motors and generators. It helps to shield the rotor from dust, debris, and other environmental factors that could affect its performance and longevity. Additionally, rotor caps can play a role in maintaining the proper alignment and balance of the rotor during operation.
The basis of general theory and generalised equation of ac machines?
The general theory of AC machines is based on the principles of electromagnetism, which link magnetic fields and electric currents. The generalized equation for AC machines typically includes components for the electromagnetic field, stator and rotor windings, and mechanical motion. These equations are used to analyze the performance and behavior of various types of AC machines like induction motors and synchronous generators.
Where can you buy a motor for a fiber optic Avon scarecrow with a synchronous motor ac12v?
You can purchase a synchronous motor like the one you described from online retailers such as Amazon or eBay. Make sure to check the motor specifications to ensure it is compatible with your Avon scarecrow. Additionally, specialty electronics stores or fiber optic component suppliers may carry such motors.
What causes motion in electrical motors?
Electricity. The energized coils in the A.C. motors' stator cause eddy currents forcing the rotor to move. A D.C. motor acts like magnets turning on to repulse the opposite magnet, pushing it away. Switching polarities so it continues.
