Either or Both - AC and or DC motor's are both rated by Horsepower / RPM / Torque, DC Motor's are more commonly used where you need to reverse the rotation on the fly (by a button push) - Crane's for example.

How do you differentiat dc motior and ac motor physicaly?
if you power an ac motor with dc or a dc motor with ac you will likely start smelling smoke and the motor will be damaged. If the motor is marked "3-phase", "shaded pole", or "induction" it is an ac motor! BTW, there are ac/dc motors that will run on both, they are wound very much like dc motors but a bit differently.
How do you change DC to ac current?
Dc current can be changed to Ac current by using an undulator.Wrong!The devices that change DC to AC are:an electronic power invertera mechanical motor-generator set (only used in very high power stationary applications)an electromechanical vibrator (now obsolete)
Can you convert a DC motor to run on AC?
The easiest way would be to convert the AC power to DC by using a rectifier diode and a filter capacitor. In that way you can now run your DC motor on DC.
How do vfd's change the AC to dc current and back into AC?
Variable frequency drives use a rectifier to "chop off" the top part of the ac wave, then use capacitors to "fill in" the gaps in the voltage, making a "near dc" power. They use IGBTs, a fancy term for a high speed, high current transistor, or electronic switch, to pulse the "near dc" power out to the motor, in a pattern that appears like ac to the motor.
Why ac motors are not used in railways?
Ac motor has a low starting torque so that DC series motor used in railways cause DC motor has high starting torque
Whether a pmbldc motor is a dc or ac motor?
PMBLDC machine is actually an ac machine and due to power electronics components it's output is dc ,so therefor it is called 'dc'
Can a ac motor produce electricity?
Technically YES. But the source of power in Electric cars being DC through batteries, the motor must be DC and not AC.
What is the different between ac dc motors?
DC Motor works on DC source and AC motor works on AC source
When using electronics what device is capable of changing DC to AC?
A device called a power inverter.In old vacuum tube radios an electromechanical device called a vibrator was used.Another device is a motor-generator using a DC motor and an AC generator.
What is AC motor and DC motor?
AC stands for alternating current, and DC is direct current. A motor is a device that uses electrical energy to spin. An AC motor uses AC voltage, and a DC motor uses DC voltage. http://ezinearticles.com/?The-Difference-Between-AC-and-DC-Electric-Motors&id=193767
Which instrument is suitable for measuring both a.c. and d.c. quantities.?
We use the "MOTOR GENERATOR SET" to convert the DC power to AC power we use DC motor and ac generator in it. It is very efficient way to convert the DC power to AC power.
Can DC series motor work on ac and DC and why?
A dc series motor can work on dc and ac because dc motors are totally reversible.
