Can you run a 60hz 110V motor on 50 hz 220V with a step down transformer?
NO dear we can not rotate a 110 vlolt motor on 220,but if your voltage is 110v then y can rotate it on 50hz ,no problem,but it will rotate at lower speed, ENGR. NASEER AHMED,PAKISTAN
Why don't the transformers rotate as InductionMotors when they are given AC supply?
The transformer components don't rotate (or move at all) simply because they are rigidly mounted. If you suspend a thin wire in the air close to an iron object, and pass a current through the wire, it will move, being attracted toward the iron by the magnetic field produced by the current. Motors are specially arranged with the magnetic field in just the right spot so that it acts on the armature to cause rotation. Of course the armature rides on bearings so it can rotate. Transformers have no components that are free to move, and the magnetic field is directed so as to induce a voltage in the secondary winding. That's what transformers do. Nothing inside the transformer is free to rotate. Interestingly, if you ever get a chance to stand near a large transformer, you will hear a buzz or humming sound. This is the wires and iron core actually moving a very tiny amount as the magnetic field acts on them. There is no rotation though, just a small vibration back and forth as the magnetic field builds and collapses.
Does a dynamo have mechanical load or does it rotate freely without much efforts like a bearing?
It rotates freely until it is required to do work. As soon as a load is placed across the output more effort will be required to rotate the Dynamo.
Why are transformer more efficient that rotating electric machines?
Because the electrical parts of a transformer do not move / rotate.
What are the uses of footstep bearing?
A footstep bearing is essentially a cast-iron block with a gunmetal bush that has a hollow collar fitted on its top. This bearing is used to keep the shaft upright in a vertical position. The shaft is fixed in place and not allowed to rotate by a pin.
Why transformer does not rotate like induction motor Inspite both having same principle?
because transformer has primary and secondary windings only but in motor has stator has two windings and rotorAnswerIt could be something to do with the part that there are no moving parts!
What part does a wheel and tire rotate on?
They rotate on the wheel hub, which houses the wheel bearing.
What is the use of plummer block?
it used to rotate the bearing
When checking the main bearing fits with plastigage?
do not rotate crankshaft
What does a motor bearing do?
A main bearing gives the crankshaft a smooth surface to spin on, and a rod bearing, provides a surface for the connecting rod to rotate on.
How do you make a model of of earth obit the the sun rotate?
Attach a suzan bearing to it :)
What is an inducting motor?
induction motor has two control system one is stator control another rotor control And it comes under the category of asynchronous motors. The term induction is because the rotor of an a.c motor does not receive the electric power through conduction but by induction same as the secondary of the transformer receives the power from primary. And so an induction motor can also be called as a rotating transformer i.e. one in which primary is stationary and secondary is free to rotate.
Major difference between thrust radial bearing?
thrust bearing takes axial loads radial bearing takes radial loads axis is line about which races or ring rotate
Why transformer not rotating?
transformer is not rotating bcoz for rotating rotating magnetic field is required which is produced only when the current is passed through the windings which are displaced physically by 120degrees and phase difference of 120 degrees where as in transformer there is no phsical displacement of 120degrees hence transformer cannot rotate.
State the important difference between a transformer and induction motor?
A transformer uses a varying magnetic field to induce a voltage in another winding, often changing the voltage to match the requirements of the load.A motor uses a varying magnetic field in induce a torque in the armature, making it turn, converting electrical energy into mechanical energy. In the case of an induction motor, the "windings" in the armature are built in as "single turn shorted secondary windings", rather than windings connected via slip rings or commutators, but the end result is the same - opposing and attracting magnetic fields cause the armature to rotate.

What causes loud humming sound on rear of Mercury Cougar?
Bad Tire or wheel bearing, rotate the tires to the front if the noise follows its the tire if remains in rear its the wheel bearing
