METHOD FOR RELATIVE INSTALLATION OF SYNCHRONOUS MOTORS Russian patent published in 1997 - IPC

FIELD: electric drives. SUBSTANCE: method for relative installation of n synchronous motors whose rotors are connected to common shaft of load upon turning the stators involves application of ac voltage to first phase winding the stators involves application of ac voltage to first phase winding of first synchronous motor, measurement of voltage across its second phase winding, turning of common load shaft until voltage being measured drops to zero, fixation of load shaft, and sequential application of ac voltage to first phase winding of each of (n-1) synchronous motors. Voltage across second phase winding of each motor is measured while turning respective stator until voltage being measured drops to zero; upon turning the stator of last motor, ac voltage is disconnected from first phase windings of n synchronous motors. EFFECT: improved installation precision and facilitated implementation of method.
