Yes. This is called motoring, and is generally a bad thing; instead of producing power, the generator begins to suck in power, which causes a strain to the power system. Many generators employ special protective relays to prevent operation as motors (usually denoted '32', or a directional relay).
I believe some generators (specifically hydro units) are intentionally run like a motor (but without load) to provide power factor correction. I can't find my references for this though, and have no direct experience with it.

∙ 14y agoInduction motor runs on the principle of torque created between rotational magnetic field and the current flowing through the closed rotor connection. Now as long as Nr and Ns are different, there will be torque.
The moment when Nr (rotor speed) becomes = Ns (synchronous speed), torque will be vanished and hence the motor can't run.

How does the starting of synchronous motor using dc generator as a load work-?
Starting of the synchronous motor using the DC generator creates a magnetic field.
Difference between synchronous generator and synchronous motor?
ASYNCHRONOUS is a mode whereby events happens irregardless of control. SYNCHRONOUS are this same events but controlled by a timing and/or control
Why synchronous motor is called synchronous capacitors?
A synchronous motor can operate as either a Generator or a Motor.When a synchronous motor has current applied to the windings on its rotor and the stator is energized with say a 50hz line supply (with little or no physical load) then the exact amount of excitation provided by the rotor can determine whether the stator displays inductive or capacitive properties.If the rotor is under excited (too Little rotor current) the Synchronous Motor will behave as an Inductor, however if the rotor is over excited then the Synchronous Motor will behave like a Capacitor.Hope this helps
Which motor rotate above synchronous speed?
An induction motor rotating at higher than synchronous speed would be generating power, thus would be a generator. No motor operating as a motor runs above synchronous speed.
If a three phase induction motor runs at a speed greater than synchronous speed?
When an induction motor is pushed over synchronous speed it will become a generator and will deliver power back to the utility.
How does the starting of synchronous motor using dc generator as a load work-?
Starting of the synchronous motor using the DC generator creates a magnetic field.
What is synchronous machein?
mainly alternator,synchronous motor comes under the synchronous machine.a synchronous motor is not a self starting motor.if a synchronous motor moves with more than synchronous speed then it acts as a synchronous generator.

What are the advantages of induction motor?
1. Induction motor has high starting torque, therefore use for operate pump which need high starting torque. 2. Induction motor operate on variable speed. 3. It can be used as generator when speed of motor is higher than synchronous speed.
Which motor rotate above synchronous speed?
An induction motor rotating at higher than synchronous speed would be generating power, thus would be a generator. No motor operating as a motor runs above synchronous speed.
Why A synchronous motor is sometimes called a synchronous capacitor Explain?
A synchronous motor can operate as either a Generator or a Motor.When a synchronous motor has current applied to the windings on its rotor and the stator is energized with say a 50hz line supply (with little or no physical load) then the exact amount of excitation provided by the rotor can determine whether the stator displays inductive or capacitive properties.If the rotor is under excited (too Little rotor current) the Synchronous Motor will behave as an Inductor, however if the rotor is over excited then the Synchronous Motor will behave like a Capacitor.Hope this helps
You Have 6.6 Kv No Break Synchronous Generator and working as synchronous motor in normal case and there 3 c.t on star point this c. t sens the current only when working as generator anybody knew how?
when generator works as a motor then the cuurrent path is reversd.
Can a motor operate as generator?
Yes, by giving mechanical power to motor . It acts as a Generator.
Why is the frequency of a synchronous generator locked into its rate of shaft rotation?
By definition a synchronous generator must be synchronous. If it is not "locked in" it is not a synchronous generator, but an induction machine.
Short Circuit test of a Synchronous Generator?
synchronous generator
If a three phase induction motor runs at a speed greater than synchronous speed?
When an induction motor is pushed over synchronous speed it will become a generator and will deliver power back to the utility.
