there is a 10HP three-phase synchronous motor, which regularlyoperates in nominal conditions; under which it has been measuredthat it delivers a power of approximately 7542W, with a torque onits axis of around 78.4N-m.
Its nameplate voltage is 472VLL, its stator is star wired, andits rotor is standard wired. And it is powered by a three-phasedelta transformer.
To maximize the use of the equipment, it was decided to transferthe motor to a different application, in which it is required touse a frequency variator to modify its working speed; and feed themotor from another three-phase transformer, which has a starconfiguration and a 479VLL voltage.
Determine what the motor speed will be in rpm when the VFD isset to 69.9 Hz.
