Direct current or DC electric motors work for situations where speed needs to be controlled. DC motors have a stable and continuous current. DC motors were the first and earliest motors used. They were found, however, to not be as good at producing power over long lengths. Electric companies found using DC motors to generate electric did not work because the power was lost as the electric was transmitted. Brush DC motors use rings that conduct the current and form the magnetic drive that powers the rotor. Brushless DC motors use a switch to produce the magnetic drive that powers the rotor. Direct current motors are often found in appliances around the home. Alternating current or AC electric motors are used differently based on what type of AC motor it is. Single phase AC motors are known as general purpose motors. They work well in many different situations. These AC motors work great for systems that are hard to start because they need a lot of power up front. Three phase, also called polyphase, AC motors are usually found in industrial settings. These motors also have high starting power built transmit lower levels of overall power. AC power gets its name from the fact that it alternates in power. The amount of power given off by an AC motor is determined by the amount of power needed to operate the system. gary
DC motors are of mainly 3 types.series motors, shunt motors, and compound motors. DC motors are mainly used where high torque is required from less speed (rpm),and a constant rpm can be maintained.
Used mainly in : lathe ,drill machines, grinding machines, compressors and so on.
Ac machines have less expenses. Used widely because Ac is more popular. They have less torque on slow speeds.
Used on cooling fans, water pumps etc.
DC motor has commutator to convert AC into DC. but incase of AC there is no commutator
The electric motor changes electric energy into mechanical energy.
Electric motor is a machine that converts electrical energy to mechanical energy while a Galvanometer is an electrical instrument that measures small values of current.
Motor started will have overloads the contactor connect es line voltage.
the voltage tolerance of a standard electric motor is
An electric motor converts electrical energy to kinetic energy.
drive usually makes the motor go
the difference between a electric motor and a generator.Motor- is a device or equipment which convert electrical energy to mechanical energy.Generator- is a device or equipment which convert mechanical energy to electrical energy.
An electric motor converts electric energy to mechanical energy while a generator converts mechanical energy to electric energy.
Max torque and breakdown toarque are the same...,.the point at which a motor will stop/stall.
An electric motor is an electromechanical energy conversion devicewhereas an electric drive is that which involves control of speed or position of the motor.
Motor vehicles are powered by an engine or motor (gas, diesel, electric, etc.). Horse-drawn vehicles are powered by a horse.
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.
The main difference is in hybrid cars there are a small petrol engine and a electric motor. When the car is driving along at slower speeds the Electric motor is driving the car while the petrol engine recharges the battery but when the speed is greater the Engine And Electric Motor Drives The Car
A manual treadmill takes no electricity and uses resistance. The person running on it makes it work. Electric moves at set speeds by motor.
The main difference between hybrid and non-hybrid vehicles is that hybrid vehicles use a bank of batteries along with an electric motor to power the car.
There is no difference between the term "motor ship" and the term "motor vessel." The two are commonly used interchangeably.
AC motor produce mechanical power and absorbed electric energy the power generator produce electrical power absorbed mechanical power
