What else can I help you with?
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 are the ac series motors preferred for electric traction?
ac motor is nothing but induction motor.So check out for characteristics of induction motors.
What is need to operate an electric motor?
Voltage is needed for both AC and DC motors.
What electric motor does an electric car use?
A electric car uses either a DC or AC motor. Typically they use DC motors.
What does AC stand for in physics?
AC stands for alternating current in physics. It is an electric current that reverses direction at regular intervals, typically used in power distribution and for electric motors.
What is a BTD when dealing with large HP electric AC motors?
BTD stands for bearing temperature detector.
Are the fan motors on fanuc ac spindle motors ac or dc?
usually ac 110v even on the dc motors
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.

Who is correct Technician a says AC stands for alternating voyage. Technician b says DC is used in electric motors on most hybrid vehicles.?
Technician A is incorrect; AC stands for alternating current, not "alternating voyage." Technician B is partially correct; while DC (direct current) is commonly used in electric motors for hybrid vehicles, many hybrid systems also utilize AC motors. Thus, both technicians have inaccuracies in their statements.
