A core with three legs is shown in Figure Q6. Its depth is 5 em, and there are 200 turns on the leftmost leg. The relative permeability of the core can be assumed to be 1500 and constant. Caleulate the amount of flux and flux density that exists in each of the legs Assume a 4% increase in the effective area of the air gap due to fringing effects ст 25 cm 15 cm- 25 cm 9 cm 2 A 200 tums -0.04 cm 25 cm 9 cm Figure Q6 A ferromagnetic core with three legs

A: In this question,   We need to determine the speed and efficiency of the generator

Gear Motor

A gear motor is a combination of a gearbox and an electric motor. This combination of two systems is used for efficient usage of the motor. It makes a cost-effective solution for high torque, low-speed applications. These motors are used in our household as, garage door openers, alarm clocks. In commercial areas, hospital beds, cranes.
