How do you rotate a shaft?
I presume you are talking about how to change the direction of rotaion on an electric motor. To change the direction of a three phase motor, switch any two wires of the three phase feed, and the motor will rotate in the opposite direction.
Who invented the hand drill and why?
Various people invented different hand drills during WW1. - Why- they were more efficient than drilling by hand, once the small electric motor was available.
What was used before the electric drill?
Before the electric drill , it was done by hand. There's a hand-cranked drill, probably still used by the Amish. My father owned one.
What the applecation of universal motor?
universal motor r mostly used for domestic purpose applicatios like the vaccum cleaner,foodprocessors and mixeshair driers,coffee grinders,electric shavers etc....another applications for blowers.
Where does the ground earth wire go once it is connected to the motor on a two stroke trimmer motor?
On a hand-held machine like a strimmer the earth wire is there to ensure that all the metal parts of the strimmer - that could be touched - are connected together and therefore are all at the same voltage, to avoid electric shocks.Another AnswerNot sure why a 'two-stroke' trimmer motor would require an earth wire as it would not require an electricity supply.
Why motor need pole?
electric and magnetic go hand in hand. One needed to produce other. Motor no magnetic pole, motor no work.
What are the comparisons between motors and generators?
Electric Motors • The electric motor converts electrical energy into mechanical energy • The shaft of a motor is driven by the magnetic forces developed between the armature and field • Current has to be supplied to the armature winding. • Motors obey Fleming`s Left Hand Rule • Electric Motors Fleming`s Left Hand Rule The Left Hand Rule shows what happens when charged particles enter a magnetic field. Generators • A generator converts mechanical energy into electrical energy. • A shaft attached to the rotor is driven by a mechanical force • Electric current is produced in the armature windings. • Generators obey Fleming's Right Hand Rule • Generators The Right Hand Rule shows how a current-carrying wire generates a magnetic field.
An example of an energy input to a genarator is?
Whatever is turning the shaft (turbine, motor, hand crank, etc.).
What is the point of having an electric motor?
It makes work easier than doing everything by hand without the motor.
What kind of threads are on the main shaft nut Left or right hand?
On all Harleys the transmission mainshaft has lefthand threads. The motor's sprocket shaft has righthand threads.
Why are hybrid cars not designed like diesel electric locomotives?
To a certain extent they are. The engine provides motive power when the electric motor does not have enough power for the task in hand. The engine also charges the batteries that run the electric motor.
What is the different between hand tools and power tools?
Hand tools as suggested by the name are hand powered. Power tools all have a motor, usually electric.
How do you rotate a shaft?

How do you crank the engine on a motor boat?
There are many different ways. On an outboard motor it can be a rope, pulley or an electric motor. Inboard engines are usually bigger and have electric, pnuematic or hydraulic starters. They can also be turned over with a hand crank if not too large.

What makes an electric kitchen mixer work?
The general answer is that the electric motor makes it go. Electricity is converted to mechanical energy by the motor, and the power is transferred through gears (to correct speed) and coupled to the mixing head or to the mixer blade shafts.
How an electric motor from electric generator?
You can use your permanent magnet electric motor as a generator. All you have to do is spin the shaft of any permanent magnet electric motor with an external power source, and your motor will turn into a generator. You can create an electric current with almost any motor if it is properly wired and used according to precise guidelines. As a result, you can't simply reverse the components of a generator to turn it into a motor. Brushed and brushless DC motors can both be used to generate electricity.
