Why is a motor rated in KW's and a transformer rated in?
The mechanical load of a motor determines the necessary output power rating of an electric motor. As mechanical loads are defined in terms of watts (or, in North America, horse power), then motor's output must be rated in watts, too.The so-called 'power' rating of a transformer is determined by the rated voltage and the rated current of its secondary winding. The product of these two quantities is the transformer's rated 'apparent power', expressed in volt amperes.Incidentally, the symbol for "kilowatts" is "kW", not"KW's"!
Why starting currrent is higher in 3 phase id motor than 3 phase transformer?
CLARIFICATION AND ANSWER: 1. STARTING CURRENT PRODUCED ONLY BY ITS LOAD NOT SOURCE(SAY STEPDOWN TRAFO) 2. IF THE INDUCTION MOTOR IS THE ONLY LOAD OF THE STEP DOWN TRANSFORMER (SOURCE)-THE READING WILL BE AND SHOULD BE THE SAME IN THE SECONDARY SIDE UNLESS YOUR AMMETER IS IN THE PRIMARY SURELY WILL READ LOWER BUT POWER CONSUMPTION REMAINS THE SAME. 3. IT ALSO DEPENDS ON THE RATING OF THE MOTOR LOAD AND THE TYPE OF STARTING METHOD USED THAT YOU CAN MEASURE STARTING CURRENT.
What kind of outlet is needed for a sump pump?
Outlet rating should be suitable to the rating of the motor. The type should be preferably IP 55 or higher if mounted outside the sump in dry area.
Why is the motor of the transformer locked?
The only motor associated with a transformer is an on-line tap changing mechanism motor! So your question doesn't really make any sense!
Can a 125 HP 3 phase 460 volt saw be started with an across the line starter?
CAN and WILL BE ALLOWED TO are different questions. Whether or not the motor CAN be started across the line will depend on the available short circuit current (SCC) at your location on the local utility's power distribution grid, and the rating of your service transformer. Check with your utility company. It may be possible to start the motor across the line, based on the transformer rating, but if there is not enough SCC, the utility will not allow you to connect the load without a starter or variable frequency drive system.
What size of wire should i use with a 50hz motor?
Depends on the current rating which should be on the motor.

How do you start a DC motor if there is no 3 point starter?
By the use of auto transformer and bridge rectifier we can start dc motor.
How do you calculate amount of copper used in a motor AC or DC and generator and transformer Datasheets do provide power rating and mass of the equipment can we somehow use this available info?
One thing you could do is look up the datasheet for the motor and/or contact the manufacturer of the motor. Also, if you know the guage of wire, you can calculate it based on the resistance of the coils on the motor/generator or on the coils of the transformer
What capacitor should you use on my step up transformer with an output of 220v so you can use it to run my 220v 60hz motor?
If you have a transformer with an output adequate to run the motor, use it directly for the supply to the motor control circuitry. Remember when dealing with motors, the start current will be about 300% of the full load running amperage. Size the transformer accordingly.
How many watt transformer is needed for 2.5 amp motor?
Need to know the voltage of the motor and primary voltage of the transformer.
Difference between transformer and induction motor?
1. Induction Motor has an air-gap but transformer has no air gap rather it is mutually link. 2. Induction Motor has high no-load current than transformer. 3. Induction Motor is a dynamic device. 4. Induction Motor has high power factor.

What devices transformer electrical energy into mechanical energy?
An electric motor, such as a starting motor

How do you load a transformer?
Anything that draws energy from a supply is a load. So you 'load' a transformer by attaching a lamp, a motor, etc., to the transformer's secondary windings.
