Question

Write three applications of DC motors and explain them briefly.

(a) Elevators, Electric Cars, Conveyor Belts
(b) Refrigerators, Air Conditioners, Washing Machines
(c) Power Tools, Electric Fans, Robotics
(d) Wind Turbines, Power Plants, Spacecraft Propulsion

Answer 1

DC motors are used in elevators, electric cars, and conveyor belts.

Step-by-step explanation:

DC motors are used in a variety of applications. Here are three examples:

1. Elevators: DC motors are used in elevators to control the movement of the elevator car. The motor powers the pulley system that moves the elevator up and down.
2. Electric Cars: DC motors are used in electric cars to drive the wheels. The motor converts electrical energy from the batteries into mechanical energy to propel the car forward.
3. Conveyor Belts: DC motors are used in conveyor belts to transport goods or materials. The motor powers the belt, which moves the items along the conveyor.
