How does an electric motor work class 10?

The electric motor works on the principle that when a coil is placed in the magnetic field and the current passes through it resulting in rotation of the coil.

What affects electric motor efficiency?

The efficiency of an electric motor depends on the choice of materials used for the core and windings, their physical arrangement and the care and precision with which they are handled and assembled. Losses can be categorised into two groups.

IT\'S FUNNING:  Can you have a heat pump and an electric furnace?

What is the efficiency of electric motor?

Most electric motors are designed to run at 50% to 100% of rated load. Maximum efficiency is usually near 75% of rated load. Thus, a 10-horsepower (hp) motor has an acceptable load range of 5 to 10 hp; peak efficiency is at 7.5 hp. A motor’s efficiency tends to decrease dramatically below about 50% load.

Why are electric motors more efficient?

Electric motors are actually pretty simple, consisting of a central rotor, typically connected to a single gear. … Their simplicity also means that almost no energy is lost in friction between moving parts, making them far more efficient than internal combustion engines.

What is electric motor Class 10 Brainly?

Answer: An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor’s magnetic field and electric current in a wire winding to generate force in the form of rotation of a shaft.

What is the electric motor Class 10?

The Electric Motor. An electric motor is used to convert electrical energy into mechanical energy. … Motors convert electric energy to mechanical work. The opposite is done by generators that convert mechanical work to electrical energy.

What is electric motor Class 10 CBSE?

Electric motor is a device that converts electrical energy to mechanical energy. Parts of a Electric Motor. Insulated Copper wire: A rectangular coil of wire ABCD. Magnet Poles: A magnet as placed above ie North Pole and South Pole.

What causes motor efficiency?

Poor motor choice or overloading.

If the wrong choice of motor is used in an application then this can cause further inefficiency. Typically this would involve overworking a motor or gearbox which is not capable of operating in a particular application.

IT\'S FUNNING:  What electrical cable can I use underground?

How do you find the efficiency of a motor?

Typical Motor Efficiency Values: Efficiency is simply output (useful) power divided by input power, with the difference being losses due to imperfections in design and other inevitabilities. Efficiency in this context is a decimal varying from 0 to 1.0, or sometimes a percentage.

Which electric motor is most efficient?

Tests carried out on a 44 megawatt 6-pole synchronous ABB motor shortly before delivery showed an efficiency 0.25 percent greater than the 98.8 percent stipulated in the contract, resulting in the world record for electric motor efficiency.
