What generates heat when the motor is running?
The frictional losses and the resistive losses generate heat in a motor
What oil used in hydraulic bending machine?
to reduce frictional losses and increase lubrication
What is windage loss of motor?
Windage loss is essentially frictional losses acting on rotating members due to air resistance.
Which loss is not common between a transformer and rotating machines?
Frictional , rotating losses are not common to transformers and rotating machines. these are specific to rotating machines.
What are the constant losses in a DC machine?
Constant losses Those losses in a d.c. generator which remain constant at all loads are known as constant losses. The constant losses in a d.c. generator are: (a) iron losses (b) mechanical losses (c) shunt field losses
What generates heat when the motor is running?
The frictional losses and the resistive losses generate heat in a motor
Are the frictional losses of the induction machine linear?
No, the frictional losses of an induction machine are not linear. Friction losses increase with speed and are affected by factors such as temperature, lubrication, and surface finish. These losses are typically represented as a quadratic function of speed in machine modeling and analysis.
What oil used in hydraulic bending machine?
to reduce frictional losses and increase lubrication
What is the losses of three phase induction motors?
Iron Loss Copper Loss Frictional loss
Why cant a machine be one hundred percent affective?
The reason why amachine cant be one hundred percent effective is as a result of losses.For Electrical machine such as alternator we have Mechanical losses(such as windage and frictional losses)and Electrical losses(such as copper loss in the rotor winding and stator winding).In Mechanical machine the main losses are windage and frictional losses.NOTE;ALL THIS LOSSES RESULT IN THE PRODUCTION OF HEAT,THUS REDUCING THE EFFICIENCY OF THE MACHINE.
How does the amount of work the screwdriver does on the can compare with the amout of work you do on the screwdriver?
A screwdriver should be 100% efficient, if there are any small losses they will be due to deforming the screwhead, or frictional losses on the screwhead.
What affects RPMs?
Friction affects the RPM of a vehicle. Frictional losses in the engine result in a restriction in revolutions per minute.
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 is the effect of friction on the flow through a steam nozzle?
Friction in a steam nozzle can result in energy losses, reducing the efficiency of the nozzle. Frictional forces can cause pressure drops and decrease the velocity of the steam flow, impacting the overall performance of the system. Proper design and maintenance are essential to minimize frictional losses in steam nozzles.
What are the factors of thermal efficiencyhow does each factor affect thermal efficiency?
Factors of thermal efficiency include combustion efficiency, heat transfer efficiency, and frictional losses. Combustion efficiency refers to how well fuel is converted into heat energy, while heat transfer efficiency measures how effectively heat is transferred within the system. Frictional losses occur due to resistance in moving parts and can reduce overall energy output. Improving combustion efficiency, enhancing heat transfer mechanisms, and minimizing frictional losses can all help increase thermal efficiency.
What is windage loss of motor?
Windage loss is essentially frictional losses acting on rotating members due to air resistance.
Which loss is not common between a transformer and rotating machines?
Frictional , rotating losses are not common to transformers and rotating machines. these are specific to rotating machines.
