It maximizes it, by reducing the internal losses to friction.

Reduction of losses, such as those due to friction, makes a machine more efficient.

A three phase induction machine have the Following losses:- 1. Stator core loss 2.Stator Ohmic loss 3.Rotor core loss 4.Rotor ohmic loss 5.Friction losses 6.windage losses 7.Stray losses 8.Also it'll depends upon the types of motor as if it is a slip ring type IM then it will have sparking losses at slip contact etc etc which are very small in comparison to above losses.

Entropy. There are always losses - usually by friction.

User Avatar

Generally, friction losses redcuce efficiency.

User Avatar

By reducin friction between the machine parts and also by avoiding any sorts of power losses.

User Avatar

There are always energy losses within the machine due to inertia, friction, etc.

User Avatar

Reduce losses from friction so forth in transmission of power. Ensure fuel utilized to the fullest.

User Avatar

induction motor has mechanical losses whereas transformer is a static device the mechanical losses are absent hence induction motor has less efficiency

User Avatar

what are the various losses occurring in the motors

User Avatar

No. Work out is always less than work in due to friction and other losses..

User Avatar

the circle diagram of induction motor is used to find the losses and efficiency of induction motor

User Avatar

TNSTAFL There's no such thing as a free lunch. There are ALWAYS losses in any machine (friction being the most common) There is a joke exception - the electric heater ... since the losses are the desired result.

User Avatar

An efficiency factor of 1 (or 100% efficiency) is not possible due to losses that cannot be reduced to zero. These losses take the form of friction, heat loss etc.

User Avatar

There are MANY sources of Friction within the machine that we call a CAR. All of the moving parts experience frictional losses that result in Heat Generation, which results in Power losses. Even the tires Heat up due to rolling friction. So, when the engine's power is reduced below the level required to overcome all those friction losses, the CAR slows down.

Just like a transformer, the core losses are a combination of eddy current losses and hysteresis losses.

User Avatar

There are always losses in the system . Friction causing heat. Vibration taking away energy . There are no prefect systems therefore there will always be losses.

User Avatar

Because, the losses of IM is more due to the contribution of friction losses at shaft bearings and wind age losses in rotor air gap, this reduces the efficiency of the equipment, Since transforms is a static equipment zero mechanical loss so efficiency of the equipments in high .

User Avatar

(Output work) + (friction losses) = (input work) on any type of machine.

User Avatar

No. Nice idea, perpetual motion and all that, but there are too many losses e.g., friction, induction lag, electrical resistance etc

User Avatar

Use thicker wire in the windings, use a larger magnetic core, use low-friction bearings. These features reduce the power losses but might increase the mass of the motor.

User Avatar

As there are many types of losses in a machine & these losses reduces the efficiency of that machine, hence ideal machine can never be there. For an ideal machine, its efficiency should be 100% i.e. Output of the machine= Input of the machine. But in practice, due to various losses & temperature effects, our output is always less than the input. For non ideal machine, input= output + losses.

User Avatar

stray losses,armature copper losses,iron losses(Hysteresis and eddy current losses),mechanical losses(friction and windage losses)

User Avatar

Stray losses refer to secondary voltage to be inappropriately distributed to transformers, induction motors and generators. Stray losses essentially mean that there is leakage that causes a weakening of the voltage being delivered to the motor.

User Avatar

Losses of energy within the machine- some of the energy is used up by friction, and converted to heat. There is also the matter of efficency of a machine. The less efficent, the more power you must put in to get the same output.
