What is the difference between an electric motor and an engine?

The electric motor is an electrical appliance.The engine is the power supply. The engine is a mechanical power source. The generator is mainly composed of stator, rotor, end cover, electric brush, base, bearing and other components.

The difference between engines and electric motors is mainly of different properties. Electric motors are electrical equipment (electricity) and generators are equipment that generate electricity (power generation). The generator has an excitation device, but the motor does not.

The electric motor converts electrical energy into mechanical energy, and the engine converts other forms of energy (mainly internal combustion engines, in the form of chemical energy generated by burning gasoline and diesel) into mechanical energy. Electric motors are generally not transmitted by stroke (air pressure), but generates a magnetic field by electric current, which makes objects Move to occur.

Intuitively, the electric motor is a machine driven by electricity, and the engine covers a wider range. It can also include electric motors, diesel engines, gasoline engines, water turbines and other driving equipment.

What is the difference between an engine and an electric motor?

1. The difference between engines and electric motors is mainly different in nature. Electric motors are electrical equipment (electricity) and generators are equipment that generate electricity (power generation). The generator has an excitation device, but the motor does not.

2. The electric motor is an electrical equipment (electricity), and the generator is an equipment that generates electricity (power generation).The generator has excitation equipment, but the motor does not.

3. The electric motor converts electrical energy into mechanical energy, and the engine converts the energy of other forms (mainly the internal combustion engine, in the form of chemical energy generated by burning gasoline and diesel) into mechanical energy. Electric motors are generally not transmitted by the stroke (air pressure), but generates a magnetic field by electric current, which is made by the action of the magnetic field. The object moves.

4. The engine is to convert other energy into kinetic energy. The engine you mentioned should mean that the car engine is driven by gasoline, and the electric motor converts electricity into kinetic energy.

5. Electric motor is a kind of engine, which can also be driven by diesel, etc. Electric motor: It is a kind of machine that converts electrical energy into mechanical energy. Its basic principle is to use the interaction between charged conductors and magnetic fields to turn electrical energy into mechanical energy.The motor structure mainly includes two parts: rotor and stator.

6. First of all, the difference between an electric motor and a generator is the different working principle. The working principle of the motor is the effect of the magnetic field on the current force, and the generator is based on the law of electromagnetic induction and the law of electromagnetic force.

What's the difference between an electric motor and an engine?

The difference between engines and electric motors is mainly different in nature. Electric motors are electrical equipment (electricity) and generators are equipment that generate electricity (power generation). The generator has an excitation device, but the motor does not.

The properties are different. An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (gasoline engines, etc.), external combustion engines (Sterling engines, steam engines, etc.), electric motors, etc.An electric motor is a device that converts electrical energy into mechanical energy.

Electric motor is a kind of engine, which can also be driven by diesel, etc. Electric motor: It is a kind of machinery that converts electrical energy into mechanical energy. Its basic principle is to use the interaction between charged conductors and magnetic fields to turn electrical energy into mechanical energy. The motor structure mainly includes two parts: rotor and stator.

The difference between an electric motor and a generator is first of all the different working principle. The working principle of the motor is the effect of the magnetic field on the current force, and the generator is based on the law of electromagnetic induction and the law of electromagnetic force.

The direction of the magnetic field) is related to the direction. The working principle of the motor is that the magnetic field acts on the current force to make the motor rotate. It can be seen that the former uses a variety of energy drives to work to realize a certain humanSome operations, and the latter only uses electricity to achieve work, so the difference between an engine and an electric motor is that an electric motor is a kind of engine.

The generator and the electric motor are two opposite devices. The difference between the two is as follows: the function is different. The generator is driven by other energy sources, that is, it converts other energy into electrical energy; while the electric motor is used to drive other equipment, that is, to convert electrical energy into mechanical energy.
