we have two motors 1250kW,6.6kV to be coupled
on the same shaft ,so please provide assistance for their
synchronisation.
Answer Posted / Nikhilesh Kumar Kashyap
Synchronization of two motors on the same shaft involves matching the rotation speeds and phases. Here are the general steps for synchronizing two induction motors:
1. Measure and record the rotational speed (RPM) and phase sequence of each motor separately.
2. Adjust the voltage or frequency of one motor to match the RPM of the other motor as closely as possible.
3. Connect both motors in parallel, ensuring that the phase connections are properly aligned.
4. Start both motors and monitor their operation to ensure they are running smoothly and in sync. If necessary, adjust the voltage or frequency again to fine-tune the synchronization.

A voltage source of Vt = 10Vrms is connected in parallel to R and L. Determine the total current, It delivered by the voltage source Vt. 8-A series RC circuit has R = 1Mohm and C = 1microF. How long would it take for the capacitor to fully discharge if it is initially fully charged? 9-A circuit has real power = 300W and an apparent power of 500VA. Determine the power factor and phase angle. 10-The time constant for an LR series circuit is T = 0.1s and R = 10ohms. Calculate the inductance L.

A 15 kw squirrel cage motor having a maximum efficiency of 90% on a continuous full load has temperature rise of 42 degrees celcius after 30 min and 52 degrees celcius after 1 hr under the above operation conditions. a) calculate its final steady state temperature rise on continuous load and the heating time constatnt. b) if the motor is operated on a short load for 9 min estimate its temperature rise. c) calculate the maximum overload that can be applied on a short, 9 min rating so that the temperature rise is the same as the final steady state temperature rise on continuous load.
