A 3-phase, 16-pole synchronous generator has a resultant air-gap flux of 0.06 Wb per pole. The flux is distributed sinusoidally over the pole. The stator has 2 slots per pole per phase and 4 conductors per slot are accommodated in layers. The coil span is 1500 electrical. Calculate the phase and line induced voltages when the machine runs at 375 rpm.
An ac power generator produces 50 A (rms) at 3600 V. The voltage is stepped up to 100000 V by an ideal transformer and the energy is transmitted through a long distance power line which has a resistance of 100 ohms. What percentage of the power delivered by the generator is dissipated as heat in the long-distance power line?
An epicyclic gear train as shown in figure the number of teeth on gear A,B,C are 48,24,50 respectively. A) If the arm rotates with 340 rpm in clockwise find Speed of C when A is fixed Speed of A when C is fixed B) Speed of B and C when arm is fixed and A is rotating with 340
A cam with minimum radius of 88 mm rotating clockwise is required to give the motion to roller follower. The motion is as described below: 1. To move outward through 70 mm during 100 deg. With Simple harmonic motion of the cam rotaion 2. To dewell for next 80 deg. 3. To return to its starting posistion during next 90 deg with uniform acceleration. 4. To dewell for the next period of a revolution. if the diameter of the roller is 5mm then Draw the cam profile 1.when the line of the stroke of the follower passes through the center of the cam shaft and 2. when the line of the stroke of the follower is off set by 15mm.
A pinion having 40 teeth drives a gear having 80 teeth. the profile of the gear is involute with pressure angle 20, 12 mm module and 5 mm addendum. Find the length of contact 1) Arc of contact 2) Contact ratio 3) Ratio of the pitch line velocity to Sliding velocity at start point of contact and end point of the contact 4) Angle of action for pinion and gear
A single-phase two-wire feeder 1 kilometre long supplies a load of
50 A at 0.707 p.f. lagging, 35 A at 0.8 p.f. lagging and 60 A at 0.9
p.f. lagging at distance of 250 m, 500 m and 1000 m, respectively
from the feeding end. The resistance and reactance of the feeder
per kilometre length are 0.05 and 0.2, respectively. If the voltage
at the far end is to be maintained at 230 V, determine the voltage
at the receiving end?
