What else can I help you with?
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.
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.
What is the difference between synchronous motor vs induction motor and which one is better?
The big difference is that the synchronous motor's rotor can have a variable current applied to it through its field slip rings. Both types of motors have their own advantages. With a synchronous motor in the system, the systems power factor can be regulated.
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.
Applications of synchronous motor?
It is used in variety of applications such as... · Machine Tools such as a ball mill · Motor generator sets · Synchronous clocks · Timing devices · Synchronous condensers to condition electrical power · Record players · Robotics
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.......
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 is a slip in electricity?
it is the difference between the synchronous and asynchronous speed of a induction motor
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.
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.
What is slip and slip motor?
the difference between the synchronous speed and actual speed is called as slip

Difference between a generator and a motor?
A generator converts kinetic energy into electrical energy; a motor converts electrical energy into kinetic energy.
When the induction motor working as induction generator?
An induction motor connected to an existing ac supply normally runs at less than the synchronous speed by an amount described as the 'slip' which is proportional to the torque demanded at the shaft. If the same motor is instead coupled to an engine and driven at a speed higher than the synchronous speed, with negative slip, power then travels back into the ac supply and the motor has become a generator. The amount of power produced depends on the speed. However a normal induction motor will not behave as a stand-alone ac generator. For ac power generation synchronous generators are invariably used because it is necessary to set and maintain the frequency of the supply accurately.
