Which law is used to find direction of rotation of motor?

The direction of the rotation of the motor is determined by the Flemings left-hand rule. Flemings laws can be summarized as whenever, a current-carrying conductor comes under a magnetic field, there will be a force acting on the conductor, and on the other hand, if a conductor is forcefully brought under a magnetic field, there will be an induced current in that conductor.

How to Calculate EMF of DC Motor using EMF Equation?

EMF of DC Motor using EMF Equation calculator uses Induced Back EMF=Number of poles*Magnetic Flux*Number of conductors*Motor Speed/(60*Number of parallel paths) to calculate the Induced Back EMF, The EMF of DC Motor using EMF Equation that a motor has coils turning inside magnetic fields, and a coil turning inside a magnetic field induces an EMF.

FAQ

What is EMF of DC Motor using EMF Equation?
The EMF of DC Motor using EMF Equation that a motor has coils turning inside magnetic fields, and a coil turning inside a magnetic field induces an EMF. This EMF, known as the back EMF, acts against the applied voltage that's causing the motor to spin in the first place and reduces the current flowing through the coils of the motor and is represented as Eb=P*ΦB*Z*N/(60*A) or Induced Back EMF=Number of poles*Magnetic Flux*Number of conductors*Motor Speed/(60*Number of parallel paths). Number of poles is the number of finite open loop poles for constructing the root locus, Magnetic flux (ΦB) is the number of magnetic field lines (also called "चुंबकीय प्रवाह घनता") passing through a surface (such as a loop of wire), The number of conductors is the variable we use for getting the correct number of conductors, Motor Speed is the speed of the rotor(motor) and The number of parallel paths in a DC machine depends on the type of armature winding used.
