AI Thread Summary
To calculate torque and RPM in a 3-pole pair synchronous motor with a line frequency of 50 Hz and mechanical power of 1200 W, the angular velocity of the rotary magnetic field must first be determined. The discussion emphasizes the importance of showing working steps for calculations to receive assistance. The user seeks to find the number of rotations per minute and the torque of the motor. It is noted that simply stating solved values without calculations does not meet forum or examination standards. Clear and detailed calculations are essential for accurate results and assistance.

Hi Marketgirl. You are required to show some working before you can be assisted in these forums.

The notation (i solved this one) [/color] in lieu of any working does not earn credit in examinations, nor does it here, unfortunately.
