simply put a motor consumes power and a generator produces it.
reactance of a generator = - reactance of a motor

What is the response time of the stepper motor if its step angle is 12 degrees?
I don't believe the response time of a stepper motor depends on the step angle.
What is a step angle?
The nominal angle through which the step motor shaft rotates between adjacent step positions.
What are the Applications of differential compound?
Differential compounded generators are used in Ward Lenard motor generator loops. The shunt fields on these generators are separately excited and when the shunt field polarity is reversed by the controller the series field helps drive the generator voltage to zero thus aiding in the reversal of current.
What is the small right angle tube on the front of the motor that looks like it is made of some kind of plastic?
my slonggg is hard over babestation (cole)
How are electromagnets used in real life?
Electromagnets are used to lift large masses of magnetic materials, such as scrap iron. They are essential to the design of the electric generator and electric motor and are also employed in doorbells, circuit breakers, television receivers, loudspeakers, atomic particle accelerators, and electromagnetic brakes and clutches. Electromagnetic propulsion systems can provide motive power for spacecraft.
Difference between induction motor and induction generator?
in case of induction motor the rotor speed is less than synchronous speed giving positive slip but in case of generator the rptor speed is greater than synchronous speed giving negative slip.......
Would an electric motor run in reverse if wired positive to negative and negative to positive?
A simple one would.
How do you connect two twelve volt batteries for my motor home?
You will want to connect them in "parallel" (positive to positive, negative to negative). If you connect them in "series" (positive to negative) you will add one voltage to the other, making 24 volts.
What is the difference between D.C Motor and D.C Generator?
Both are simply opposite. First of all a motor is any thing which produces mechanical energy with electrical energy intake and Generator is Vice-versa. It produces electrical energy with mechanical energy intake.Both are in same principle of induction but in opposite direction. Few appliances work on AC and few on DC(Alternative current,Direct current). AC has two levels to fluctuate i.e Positive and Negative where as DC has only one value to speak with,either positive or negative. Now DC Motor "needs" DC charge to operate and DC Generator "produces" DC charge as the output.
What does a negative active power means?
Let see an example. The active power absorbed by an AC motor is used to produce mechanical power delivered on the output shaft. If the mechanical power is negative (the motor is pushed to work as a brake) the active power 'absorbed' is also negative. The motor converts the mechanical power in active electrical power delivered in the electrical network. Any AC generator is supplied with negative active power, or it deliver to the network positive active power.
Can a motor operate as generator?
Yes, by giving mechanical power to motor . It acts as a Generator.
Did Mike Faraday invent the generator and motor?
Mike Faraday did invent the generator and motor.
How do you find the positive and negative terminal on disc motor?
Never heard of a disc motor. If you are interested open a discuss question page.
How does ac electric motor convert in to an alternator?
a motor is a generator and a generator is a motor, if you are applying a voltage to turn the rotor its a motor and if you are turning the rotor and taking the voltage off the terminals its a generator or alternator.
What is positive power and negative power?
x raised to a positive power, a is xa where a> 0. If a is an integer then it is equal to x*x*...*x where there are a lots of x.x raised to a negative power is the same as the reciprocal of x raised to the absolute value of the power. Thus, if b < 0 then xb = 1/x-bwhere -b > 0.x raised to rational or irrational powers are defined using the power laws.Another AnswerThe terms 'positive' and 'negative' powercan also be used to describe the direction of energy flow. For example, when a generator supplies energy to the grid, we can say that the direction of that energy and, therefore, the rate at which the energy flows (i.e. power) is positive. However, when the grid supplies energy back to the generator (causing it to 'motor'), then the energy (and, therefore, the power) is negative.
How do you identify a motor and a generator without operation?
a motor drives something a generator is driven by something
How do you convert a DC motor to a generator?
all the electrical machines can be run either as a motor or as a generator. but dc machines, A motor can be run as generator and vice versa with little modification
