| Abstract: | ABSTRACT The general torque equation of single-phase induction motors has been extended to account for the vibrational torques, which include not only the twice supply frequency component but also other significant harmonics. The effect of the tangential vibrations on the emitted acoustic noise is investigated and is verified against measurements on an electrical fan. |
