In a factory, there is a 10HP three-phase synchronous motor, which regularly operates in nominal conditions; under which it has been measured that it delivers a power of approximately 7524W, with a torque on its axis of around 75.5N-m.
Its nameplate voltage is 462VLL, its stator is star wired, and its rotor is standard wired. And it is powered by a three-phase delta transformer.
To maximize the use of the equipment, it was decided to transfer the motor to a different application, in which it is required to use a frequency variator to modify its working speed; and feed the motor from another three-phase transformer, which has a star configuration and a 473VLL voltage.
Determine what the motor speed will be in rpm when the VFD is set to 50.9 Hz.
