Why must electricians be extra careful when calculating power requirements for circuits that will run motors?
The electrical code states that motor feeders have to be rated at 125% of the FLA of the motor. When wiring motor circuits always consider the ambient temperature (for wire de-rate purposes) where the motor is located and the 125% rule before selecting the correct wire size. <<>> Extra care must be taken when calculating power requirements for circuits that will carry electric motors because the current need of an electric motor is larger than calculated from its horsepower rating alone. Electric motors are highly inductive and also have an in-rush current requirement to get started. The circuit used to power an electric motor has to be capable of supplying the in-rush and steady state currents to the motor -- with an acceptable I^2-R loss on the wires.
How did Michael Faraday invent the electric motor?
Michael Faraday did not invent the electric motor, but his work laid the foundation for its development. Faraday's experiments with electromagnetism led to the discovery of electromagnetic induction, which is the principle behind how electric motors operate. His research paved the way for the invention of the modern electric motor by other scientists and engineers.
Can an electric motor act like an electric generator?
An electric generator is a device that converts mechanical energy to electrical energy. On the contrary electric motors convert electrical energy into mechanical energy. Electric motors and generators have many similarities, generator forces electrons in the winding to flow through the external circuit. The source for generating mechanical energy can be a reciprocating or turbine, an internal combustion engine, a wind turbine or a motor that is capable of generating electricity using some energy source like diesel or kerosene. Many types of electric motors can be run as generators, and vice versa. For example a starter/generator for a gas turbine or Traction motors used on vehicles often performs both tasks.

What are some devices that convert energy from electrical to other forms of energy?
Electric lights (light/heat), electric motors (mechanical energy), heaters (heat), batteries under charge (chemical energy).
How electric current flow in washing machine?
A washing machine motor is similar to any electric motor. It is an AC (alternating current) electric motor. There are also DC (direct current) electric motors. Most electric motors in the house like in a vacuum cleaner or washing machine are AC because that is what you have in your house. Most electric motors in your car like the starter and windshield whipper motor are DC because they run on the cars DC battery system. DC and AC electric motors are a little different but work in a similar way. If you take a piece of iron and wrap a coil of wire around it it will become an electro-magnet while the current is going through the wire coil. An electric motor has special switches called brushes that turn the two or more electro magnets on and off. When you turn on the motor one of the coils is on and attracts a magnetic attached to a rotor. The magnet turns till it reaches the coil and strikes a brush that turns off the first electro magnet and turns on the next one so that the magnet keeps turning because it is now attracted to the next magnet. It keeps spinning around and around being attracted to different coils as they keep turning on and off, this of course happens very fast. What I've given you is a very simple description of how an electric motor works. Some motors are more complex with many magnets and coils but still work in this same basic way.
What kind of products does the Electric Motor Warehouse sell?
The Electric Motor Warehouse sells pool pumps and motors; other pool accessories like fencing, steps, etc.; electric motors like bathroom fan motors, air compression motors, etc.; and specifically a large collection of Dayton electric motors, including furnace blower motors and pressure washer motors.
Can electric motors be operated by using biodegradable fuel?
Electric motors use batteries not fuel. It is not electric if it uses gasoline or any other type of fuel. A gas motor can not be easily converted to using other types of fuel.
Working principle of brushless dc motor?
Traction motors are used in electrically powered rail vehicles such as electric multiple units and electric locomotives, other electric vehicles such as electric milk floats, elevators, conveyors, and trolleybuses, as well as vehicles with electrical transmission systems such as diesel-electric, electric hybrid vehicles and battery electric vehicles. Additionally, electric motors in other products (such as the main motor in a washing machine) are described as traction motors.

What do generators and motors have in common?
Electric motors and generators are electromagnetic devices that are the opposite of each other. Electric motors convert electrical energy into mechanical energy, while electric generators convert mechanical energy into electrical energy.
What are the two things that require magnets to function properly?
Among other things, electric motors, generators, particle accelerators.
What are the advantages of using a 36v hub motor in an electric vehicle?
Using a 36v hub motor in an electric vehicle offers several advantages. It provides increased power and torque, resulting in better acceleration and performance. Additionally, a 36v hub motor is more efficient, leading to longer battery life and extended driving range. This type of motor also requires less maintenance and is quieter compared to other types of motors, enhancing the overall driving experience.
Do motors have batteries?
No, electric motors do not have batteries.Most electric motors are powered from the AC power grid.Power tools and other portable devices using electric motors have batteries, but the electric motors in the tools and devices do not themselves have batteries.
What does motor mean in science?
In science, the term "motor" typically refers to a device that converts electrical or other energy into mechanical motion. This can include electric motors, combustion engines, or any other device that generates movement.
How does an electric motor look like?
A bar magnet is any RECTANGULAR object that has a magnetic field.It can be made out of any ferromagnetic substance, but it is mainly made out of iron or steel. Most of the time, a bar magnet is a pernament magnet, meaning it does not need an electric current in order for it to retain its magnetism.
What is the difference between electricmotor and generator?
Here are the main differences between an electric motor and an electric generator: Functionality: Electric motors convert electrical energy into mechanical or kinetic energy, whereas electric generators convert mechanical energy into electrical energy. Usage: Electric motors are used in fans, mixers, washing machines, and other household appliances, whereas electric generators are used as power backup during outages, in construction sites, mining areas, and agriculture. Fleming’s Rule: Electric motors follow Fleming’s left-hand rule, whereas electric generators follow Fleming’s right-hand rule. Principle: The working principle of a motor is based on the current-carrying conductor, whereas the working principle of a generator is based on electromagnetic induction. Current: In motors, the current has to be supplied to armature windings, whereas in generators, armature windings produce current. EMF: Electric motors give out back EMF, whereas electric generators produce induced EMF.
Are electric motors easier to maintain than gasoline motors?
Electric motors are generally easier and less expensive to maintain than gasoline motors for cars. Electric motors are more efficient and cleaner. There is a battery that needs to be replaced every three years, but there are no other spare parts.
