Webgenerator, induction generator, etc. DC generators are mainly two types which are Separately excited DC generator and Self-excited DC generator. According to field and armature connection, they can be further classified as DC series, shunt or compound generators respectively. 14 Cost The initial cost of an AC generator is high. WebThe DC motor working principle is that a current-carrying conductor experiences a mechanical force when placed in a magnetic field. This is known as the Lorentz force. And the direction of this force is given by FLEMING’S LEFT-HAND RULE. DC motor working principle is similar to the working principle of a DC generator. 81 and 18 on hand WebDC generator converts mechanical energy into. electrical energy. when a conductor move in a. magnetic field in such a way conductors cuts. across a magnetic flux of lines and e.m.f. produces in a generator and it is defined by. faradays law of electromagnetic induction e.m.f. causes current to flow if the conductor circuit.

WebAug 13, 2024 · The operation of the DC motor is based on the principle that when a current carrying conductor is placed in a magnetic field, a mechanical force acts on the conductor. The magnitude of the force is given by, F = B I l N e w t o n s. The direction of this is given by the Fleming’s left hand rule. WebJul 6, 2024 · Hence, the equation for induced EMF in a DC generator is given as; e = ϕ P N 60 × Z A v o l t s. Where, Z represents the total number of conductors. A stands for the number of parallel paths. P is the number of poles in the generator. Z/A = number of serially connected conductors. N represents the rotation of armature in r.p.m. 81 and 99 gcf WebJul 2, 2024 · The EMF induced in an electric generator can be explained as follows −. When the loop is in position-1, the generated EMF is zero because, the movement of coil sides is parallel to the magnetic flux. When the loop is in position-2, the coil sides are moving at an angle to the magnetic flux and hence, a small EMF is generated.
