Question

What is the principle of motor? Name some of the devices in which electric motors are used.

Answer 1

Hint:An electric motor is an electric motor which transforms electric power into mechanical energy. The interaction between the magnetic field and the electric current in a wire rolling process is used for most electric motors to create force by means of torque on the engine shaft.

Complete answer:
The electric motor principle is based on the current transmission driver producing the magnetic field. A current conductor is perpendicular to the magnetic field such that it has a power. The current conductor is put between the two magnets and linked to the battery. The current flows through the conductor and magnetic field from north to south when the battery is activated.

We realise from Fleming's left hand rule that the conductor is driven by an upward and downward force. The left hand rule of Fleming; hold the forefinger, the middle finger, and the thumb of your left hand in the correct angles to each other. Adjust your hand to show the direction of the magnetic field and the centre finger points towards the current and in the direction of the thumb points, the direction of force acting on the conductor. Direct current (DC) sources, such as batteries, rectifiers, or alternating current (AC) sources, such as power grid, inverter or electrical generators, are used to power electric motors.

In today's life, electric motors are incredibly significant and are often used in different areas, e.g. vacuum cleaners, dishwashers, computer printers, fax machines, tape recorders, presses, cars, underground stations, drainage and water treatment facilities. In industrial suppliers, blowers and pumps, machine tools, home appliances, power instruments and disc drives electric motors are found. electric motors. In electric watches, little engines may be present.

Note: In the process of propelling external mechanisms, electric engines provide linear or rotational force (tintail), for example, a fan or a lift. In general, an electric motor is built for continuous rotation or a linear movement at a considerable distance from its size. Magnetic solenoids are likewise transducers which transform electrical power into mechanical movement but may generate movement over a limited distance.
