How can you determine the difference between an AC or DC electric motor?
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. garyDC 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.

How do you calculate resistance box for slip ring motor?
To calculate the resistance for a slip ring motor, there is an equation that must be solved. This is Torque = S/R. S is the slip of the motor and R is the resistance of the motor.
What are the Applications of induction motors?
Introductionl It is becoming very popular the utilization of squirrel cageinduction motors with variable frequency drives (VFD's) in theindustry.l The advance of power electronics technology and the cost of theVFD's are making this utilization possible.l The many advantages of this type of application are:ÙSpeed variation.ÙHeavy load inertia starting.ÙHigh starting torque requirements.ÙLow starting current requirements.ÙHigh efficiency at low speed.ÙHigh power factor.l The induction motor with VFD's replaces with advantage todaythe DC motors, and wound rotor motors.
What Electrical motors convert what power to what power to power?
Electrical motors convert electrical energy into mechanical energy.
How do you calculate the amperage given the watts and voltage?
Amps = Watts / (Volts x Power Factor). The Power Factor is one for resistive loads and decreases for inductive loads like motors.
What is the SIC Code for Fluid Power Pumps and Motors?
SIC 3594 applies to FLUID POWER PUMPS AND MOTORS.
What is meant by battery operated motors?
Motors which have their electrical power supply taken from batteries.
What is the meaning of horsepower?
Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. A few equations to help you calculate horsepower: Power = Work / Time Power = (Force x Distance) / Time
What is the overal power factor is two motors connected in parallel?
It's the ratio of the total power of the two motors and their total apparent power (input side, of course.)
Does the Power Wheelchair use Servo Motors or Battery power?
Most Power wheelchairs use battery power not servo motors. These batteries are provided by many companies and are available online or in stores.
What is punchline of Honda motors?
Power of dreams
What is a diesel-electric power plant?
A diesel electric power plant is an engine that powers electric motors. The motors actually operate the machinery such as a locomotive.
Why dc series motors cannot be used in home?
DC series motors run on DC power. Homes have AC power, not DC power. You could use DC motors in homes if you have a power supply or use a battery, but it is usually more cost effective to use an AC motor.
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.
Why motors are cylindrical in shape?
because to create power
