What mechanism increase torque?
the motor
What is the difference between electromagnetic torque and load torque in electrical machines?
Electromagnetic torque and load torque are different.Electromagnetic torque is the torque that is produced inside the machine which makes the machine rotate,while load torque is the torque that is applied externally with brake drum and and spring balance.Electromagnetic torque can be varied by varying the speed of the machine,but load torque is fixed.
What mechanism can increase torque speed?
the motor
What is the explanation for the mechanism of DC in pmmc?
a pmmc has a coil suspended in permanent magnetic field.acording to the laws of electromagnetism a current carrying coil susspended in a magnetic field experiences an electromagnetic torque.This torque is counterbalanced by the mechanical torque devoloped in the coil in equlibrium.The angle teta can be measured and it is calibrated to directly give the current
What is the mechanism used to minimize torque in tricopter?
A small tilt is applied to one rotor to counteract yaw from unbalanced rotor torque
What is the name of the mechanism that produces the amount of torque?
An angular force would produce a large torque like angular momentum of a spinning wheel.
What is the name of the mechanism that produces the greatest amount of torque?
An angular force would produce a large torque like angular momentum of a spinning wheel.
Why single phase motor has low starting torque.?
The starting torque is low because this type of motor requires an additional way of ensuring that it starts rotating the right way. It is not economical to give this additional mechanism the capacity to deliver the full load torque.
What is induction motor?
Induction motor is an AC electric motor which uses electromagnetic induction to induce the electric current in the rotor to produce torque.
What is bull gear mechanism?
In a rack and pinion system, a bull gear is typically the last reduction gear in the geartrain. It transmits torque to an output pinion which is in contact with a rack.
Why electromagnetic torque opposes prime mover torque in dc generator?
It's a practical example of the conservation of energy, and is explained by Lenz's Law. The direction of the load current is such that its magnetic field will create a force acting in the opposite direction to the force causing the conductor to move in the first place.
What are the different types of torques?
There are various kinds of torques involved in opeartion of a motor:-Starting Torque: At the starting, motor has to deal with standstiill condition, this torque should be good enough to deal with friction and windageLoad Torque: It is the torque which a motor faces on apply of load.Breakdown Torque: more than this torque if more load is applied on a motor, torque generated will not increase and motor will starts slowing down
