What is the speed of a 3kW electric motor?
The speed of motion generated by a motor is not a function of its nominal power. The nominal power, 3kW in this example, is an indicator for the electric power consumed, and for the force available in the direction of motion. The speed of a motor is determined by its construction, and can cover an extremely wide range regardless of its power.
What is motor rated torque?
It is the twisting force that a motor can produce when it is running.
What is the different between 3phase plus N generator coil and motor coil?
Generator coils generate the voltage, motor coils use the generated voltage.
What wll happen if the starting winding in a split pase motor fail to energize?
The motor would not start rotating. The motor will just hum and the rotor will be stationary. If you can get the rotor to start turning the motor will still run on its run winding.I have a cement mixer that has a motor with a burnt out start winding. All I have to do is turn the barrel and the motor will start turning over. Without the start winding you have a choice of which way the motor will turn. If I turn the mixer barrel the opposite direction, the barrel will turn that way until I turn the unit off.
Is it dc motor?
Depending on the construction of the motor, most likely YES. As long as the motors components allow for the opposite flow of electricity, then the only problems would be speed (turning the motor fast enough to generate) and/or force (overcoming the interior magnetic force required to turn the motor shaft).
Even when the power supply is switched on why will a dodgem car not move until the pedal is pressed?
because the motor has to turn on
What are the advantages of using electromagnetic force to power a motor?
Electromagnetism is an efficient way in which to turn a motor. It does not produce pollution and it is otherwise environmentally safe.
How is emf induced in an alternator?
EMF or electromotive force, i.e.Voltage, is generated when the magnets inside the alternator turn within the wire coil of the alternator.
What force makes tray turn in microwave?
It's the mystical force known as "little slow-speed electric motor below the floor of the cooking chamber".
What is the mechanical force of muscle contraction is generated by?
The mechanical force of muscle contraction is generated by a sliding of thin filaments past thick ones.
Why voltage decreases when DC motor starts?
The motor's windings draw extra power from the line when the motor starts to turn because it takes more force to get the rotor spinning than to keep it spinning.
Can a bad condenser stop a motor from starting?
Yes. A shorted condenser will load the electrical supply and prevent the starter from creating the mechanical force necessary to turn over a motor.

Can you turn the kill switch to that position to crank the motor without the engine starting which would force the oil through out the motor?
No. Almost always the oil pump is mechanically driven by the rotation of the engine. When you turn it over, the pump also turns.
What has to be built for wind energy to be used?
Wind Turbines. They have a motor inside of them that produces energy when the blades of the turbine turn and when they turn energy is generated by the wind turning the blades and the motor. <><><> In addition to the wind turbines, you need a grid of powerlines to carry the electricity to where it will be used. This frequently costs more than the wind turbines.
What is the force of attraction or repulsion generated by moving or spinning electric charges?
it is magnetic force
Does induction motor has rotor winding?
Yes, the induction motor has a rotor winding. It is usually one turn, shorted. This is how the magnetic fields generated in the stator induce a current in the rotor, which subsequently generates a torque from the opposing magnetic fields, stator to rotor.
