How much copper in a 100 HP electric motor 100 HP electric Chicago air compressor motor?
The amount of copper in a particular motor is not determined by horsepower only, there is no relationship between the total weight of MAGNET WIRE to the HORSEPOWER of an electric motor. Determining factors are the vintage, frame, make, speed, and frame designation.
What is difference IN DRIVE AND MOTOR?
An electric motor is an electromechanical energy conversion devicewhereas an electric drive is that which involves control of speed or position of the motor.
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.
Does the RPM of a motor vary if a load is added to the motor?
The speed of an electric motor is directly proportional to the frequency of supply. The rpm written on the name plate is the maximum operating speed for the motor design. Typically, for a squirrel cage induction motors, the speed is constant by design and this type of motor cannot operate for a long time at speeds below the rated value. It is true that loading affects motor speed to some extend but the electric motor will accelerate to the rated speed. If the loading is within the design parameters of the motor, the electric motor speed will not drop. What typically happens is that if the loading increases, the speed goes down, and the current increases. Because voltage is constant, this result in a high I2R loss in the windings and the motor circuit protection trips on thermal and electrical overload. The formula for electric motor speed is SRPM=(120f)/P. The above is for AC motors. If you are referring to a DC motor, what you have stated is correct. The motor will slow down as load is added. That is why you are not supposed to run many DC motors under no load conditions - they will overspeed.
Replace two speed electric motor with single speed electric motor?
Replace with single speed of the same electrical, speed, and mechanical considerations for mounting, choosing the preferred speed from the existing two speed. In general it is common practice especially in the HVAC industry to replace a three speed motor with a four speed motor, using only three of the speeds that match the existing. Replacement must be with a single speed of the same horsepower, torque, and other electrical considerations of the needed or preferred two speed choice of speeds. Often the choice of speed, changes the horsepower or torque.
What the factor affect the speed of DC motor?

What factors affect the speed of sound in a medium?
Temperature, coefficient of restitution, density are some of the factors that affect the speed of sound in a medium.
What is the relationship between torque and speed for an electric motor?
Torque and speed are inversely proportional
Does the number of batteries affect the speed of a motor?
If they are connected in series the voltages will add and, theoretically, proportionally speed up the motor.

3 factors that affect the speed of an enzyme catalysed reaction are: .Temperature .Enzyme Concentartion .Substrate concentration
What is the name of electric motor in which both rotor and stator fields rotate with same speed?
only synchronous motor

Why 3 phase induction motor never atteined sinkronas speed?
Induction motors run at sub synchronous speeds because the slip (difference between synchronous and actual speed) causes, or controls the electric field strength in the motor. As more load is put on the motor, the motor's speed decreases, increasing slip, and increasing the electric field strength.
