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 torque applied on the motor’s shaft.

How does a simple electric motor work?
This simple electric motor works by the magnetic force F = IL x B. … The magnetic field at both of these spots points in the same direction. Thus, the magnetic force on the wire at opposite ends of the loop points in opposite directions, causing it to spin.
What are 2 household appliances that use an electric motor?
The electric washing machine, invented Alva J. Fisher in 1906, is a common home appliance that makes use of an electric motor. Other home appliances that use electric motors include clothes dryers, vacuum cleaners, fans, air conditioners, refrigerators and freezers.
What makes an electric motor more powerful?
The strength of the motor (torque) is determined by voltage and the length of the wire in an electromagnet in the stator, the longer the wire (which means more coils in the stator) the stronger the magnetic field. This means more power to turn the rotor.
Where can electric motors be found?
Electric motors are found in industrial fans, blowers and pumps, machine tools, household appliances, power tools and disk drives. Small motors may be found in electric watches.
Why do we need electric motors?
An electric motor generates power through the interaction between the motors winding currents and magnetic field and then converts that electrical energy into motion or mechanical energy. …10 мая 2018 г.
What is electric motor with diagram?
An electric motor is a device that converts electrical energy into mechanical energy. Diagram: Electric motor. Working of an electric motor: An electric motor works on the principle of magnetic effect of electric current. In an electric motor, a rectangular coil ABCD in placed between two magnets in poles N and S.
What are the 6 parts of an electric motor?

What are the basic parts of a simple electric motor?
A simple motor has the following parts:
- A power supply – mostly DC for a simple motor.
- Field Magnet – could be a permanent magnet or an electromagnet.
- An Armature or rotor.
What appliances use AC motors?
General uses for AC motors include pumps, water heaters, lawn and garden equipment, ovens, and off-road motorized equipment. In fact, many of the appliances, equipment and tools you use on a daily basis are powered by an AC motor.
What is an example of a motor?
An example of a motor is the steam engine of a train. Motor is defined as something having to do with muscular movement. An example of motor is being able to move your arms up and down, to have motor skills. Something, such as a machine or an engine, that produces or imparts motion.
Does an oven have a motor?
The function of the fan motor is to stabilise the oven temperature, in effect to distribute the heat more evenly though the oven cavity giving the user greater temperature stability and therefore more reliable and consistent cooking results.

What size electric motor do I need?
General rule of thumb: you need at least 2 lbs. of thrust for every 100 lbs. of fully-loaded boat weight (people and gear included).
Why do electric motors lose torque at high rpm?
Because doing so would compromise efficiency and drivability. As engine speed increases, so does it’s inefficiency. Higher RPMs cause more wear, and waste more fuel. For that reason, vehicles usually cruise at a engine speed much below the point where they make maximum power.
