Why friction and windage loss for an induction motor remain constant with change of stator voltage?
Because the RPM remains same
What is windage loss in a dc machine?
Friction losses due to airCommentIt's worth pointing out that the windage is pronounced 'wind-age' (i.e. 'wind' as in breeze, not 'wind' as in coil!), and not 'winde-age'.
What are the possible losses for a dc generator?
Friction in the bearings and in the commutator, and windage loss. Electrical resistance of the armature and field windings and the brushes.
What is the efficiency of a 12 volt electric motor?
Efficiency of any electrical machine is maximum when the load on that machine is such that the variable loss ( copper loss) is equal to constant loss (eddy current loss, hysteresis etc).the same applies to dc machines too.
Core loss of an induction motor?
Just like a transformer, the core losses are a combination of eddy current losses and hysteresis losses.
Why friction and windage loss for an induction motor remain constant with change of stator voltage?
Because the RPM remains same
Is there any windage loss in transformer?
In this context, 'wind', in 'windage', is pronounced as 'wind' -as in 'breeze' or 'gale'. 'Windage means air-resistance, and this only applies to rotating machines, such as generators and motors, whose rotors have to overcome air-resistance (windage) as they rotate. As transformers have no moving parts, they are NOT subject to windage loss!
What is mechanical loss in dc machines?
Friction and windage causes mechanical loss in DC machines.
What is windage loss in a dc machine?
Friction losses due to airCommentIt's worth pointing out that the windage is pronounced 'wind-age' (i.e. 'wind' as in breeze, not 'wind' as in coil!), and not 'winde-age'.
What are the possible losses for a dc generator?
Friction in the bearings and in the commutator, and windage loss. Electrical resistance of the armature and field windings and the brushes.
Why torque is not zero in no-load speed?
Because even on no load the motor has frictional losses in the bearings and windage around the rotor.
What causes 3-phase motors to heat up?
It is not only 3 phase motor, but every electrical device heats up. The reason is the current flowing through the windings causes the I^2*R heat loss. Apart from that, in case of an induction motor, the alternate cycle of magnetization and demagnetization of core material causes the hysterisis loss and eddy current loss. Last but not the least, there are friction and windage losses for a rotating electrical machine. All of these losses are dissipated as heat energy and hence the machine heats up.
What are the losses have an induction machines?
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. Regards,,
Why the no-load current of an induction motor is high compared to a transformer?
Because of the presence of the air-gap between stator and rotor in motor the magnetization current is much higher than that of a transformer in addition to the friction and windage losses due to the rotation of the rotor.
What neuological diseases cause loss of motor function in arms and legs?
What would cause loss of motor function in upper thighs
Which dial is which on a mossberg M4D scope windage vs elevation?
Elevation will be the one that moves it up and down. Windage will be the one that moves it from side to side.
What is Anarthia?
Loss of the motor ability that enables speech.
