METHOD FOR CALCULATING SQUIRREL-CAGE MOTOR TORQUE Russian patent published in 2004 - IPC

Abstract RU 2243572 C2

FIELD: electrical engineering; squirrel-cage motors.

SUBSTANCE: proposed method involves calculation of squirrel-cage motor torque using equation M_t = k·Φ₁·Φ₂·sinβ, where M_t is torque; Φ₁ and Φ₂ are magnetic circuit fluxes due to ac current in stator winding; k is coefficient of proportionality; β is angle between fluxes in electrical degrees. Rotor is found to run toward lower flux relative to higher flux including β angle ranging between 0 and 180 el. degrees.

EFFECT: enhanced efficiency of squirrel-cage motors.
