How do you determine the direction of rotation of a DC motor?
The direction of such force i.e. the direction of rotation of a motor can be determined by Fleming’s left hand. So Fleming’s right hand rule is to determine direction of induced e.m.f. i.e. for generating action while Fleming’s left hand rule is to determine direction of force experienced i.e. for motoring action.
How do you determine rotation of a motor?
There are only two possible rotations: clockwise and counter-clockwise. However, there are also two perspectives: looking at the shaft end of the motor or looking at the lead end (opposite the shaft end). A motor which turns clockwise looking at the shaft end is turning counter-clockwise when viewed from the lead end!
Which rule determines the direction of current in DC generator?
Fleming’s right hand rule:-
(for generators) shows the direction of induced current when a conductor attached to a circuit moves in a magnetic field. It can be used to determine the direction of current in a generator’s windings.
How do you change the direction of a DC motor?
The direction of rotation of DC series motor may be reversed by changing the polarity of either field or the armature winding.
Does a motor turn clockwise or counterclockwise?
Most automobile engines rotate clockwise looking at the front of the engine.
What is rotation motor direction?
Electric motors are designed either for clockwise rotation, or counter-clockwise, or both. This is very simple. The IEC standard says that the direction of rotation is always viewed from the driven end side, where the load is. … If you swap a pair of the phases, it shall rotate counter-clockwise.
Which rule is applied to identify the direction of flux in DC motor?
Fleming’s left-hand rule is used for electric motors, while Fleming’s right-hand rule is used for electric generators.
