Yes this is what we call efficiency of the motor. We give 100 but the motor in turn gives 40, so its efficiency is 40%
It spends energy overcoming friction in the motor.
Yes. But it is a negligible amount comparing to the mechanical energy it produces.
It helps to think about the purpose of an electric motor. It is designed to move things, so it produces mechanical energy. As the name suggests, such a motor gets its energy from electrical energy.
Because that is the purpose on an electric motor.
Electrical energy is transferred to mechanical energy when an electric motor is used. The electric motor uses the electrical energy to generate a magnetic field, which interacts with other magnetic fields to produce a rotating motion, thus converting electrical energy into mechanical energy.
Energy is transferred to a battery-powered fan by converting electrical energy from the battery into mechanical energy to power the fan's motor. The motor then turns the blades of the fan, converting the mechanical energy into kinetic energy that produces air movement.
A car battery produces electrical energy through chemical means, and this energy can be converted to mechanical energy such as the turning of the starter motor that starts the vehicles engine turning.
A ceiling fan converts electrical energy into mechanical energy through the use of an electric motor. The electricity powers the motor, which causes the fan blades to turn and move air. This mechanical energy produces airflow, creating the cooling effect in the room.
A motor transfers electrical energy into mechanical energy.
motor
An electric motor converts electrical energy to mechanical energy.
Chemical energy is converted to electrical energy in a battery, which is then used to power a device or equipment that converts the electrical energy into mechanical energy, such as a motor or engine that produces motion or physical work.
