An induction motor is a type of electric motor. It uses alternating current (AC) electricity and induces (hence the name) a current in the rotating part to make it move. You might call it a rotating transformer. A hydraulic motor is powered by a fluid. Typically this might be an oil, The oil forces round some gears or vanes to make the motor shaft turn. A hydraulic motor requires an external supply of pressurised fluid, e.g. oil. Large earthmoving equipment or diggers use hydraulic power as it is compact and powerful for its size.

When slip motor is negative what conduction obtained?

Your question can not be answered as it is. Reword the question - is it about induction motors or synchronous motors, for example?


What are the different types of AC motor?

slip ring, synchronous, and squirrel cage induction motors....


Why is the speed of synchronous motor is more then induction motor?

Synchronous motors run at synchronous speed. An induction motor that has the same number of poles must run at a sub-synchronous speed to create a second magnetic field (a field that is at a different phase angle) to generate torque.


When the slip ring induction motor is preferred?

larger synchronous motors start with a squirrel cage and run when dc is applied thru the slip rings small motors can have magnets in the rotor these can accelerate from rest to synchronous speed in a few seconds


What motors does not utilize electrical conductors in its rotating component A synchronous B wound rotor C universal D squirrel cage-induction?

All motors require electrical conductors in their rotor!


Why single phase induction motor always runs below the synchronous speed?

For exactly the same reason as three-phase motors always run below synchronous speed. If they were to run at synchronous speed then no voltage and, therefore, no rotor current will be induced into the rotor to drive it.


Difference between synchronous and asynchronous motors?

1)Synchronous motors are those that run only at Synchronous speed i.e. constant speed. But Motor can run in various speeds. 2)Synchronous motors runs at same speed of magnetic filed. but if one consider case of induction motor the rotor rotates at different speed than revolving magnetic field. there is slip between field and rotor.


Why the no of poles are less in induction machine compared to synchronous machine?

The number of poles determines the speed a machine has to turn (RPMs). The more poles, the slower the machine can turn. I don't believe your statement is true. I've seen synchronous generators, for example, that turn at 1200 RPMS, and induction motors that turn at ~1800RPMs.


What is the difference between synchronous motor vs induction motor and which one is better?

The big difference is that the synchronous motor's rotor can have a variable current applied to it through its field slip rings. Both types of motors have their own advantages. With a synchronous motor in the system, the systems power factor can be regulated.

What is a synchronous motor?

Synchronous motors are those that run only at Synchronous speed ie.. constant speed.


Is a 3 phase motor a Synchronous motor?

A synchronous motor can be a type of 3-Phase AC motor, or not.A synchronous motor is defined by the period of the rotor being synchronized with the frequency of the stator windings' current. The stator windings might be 3-Phase or not (2-Phase would work).Also synchronous motors are not the only type of 3-Phase AC motors. An induction motor could also be 3-Phase AC and has a few advantages and disadvantages over a synchronous motor.
