FIELD: electricity. ^ SUBSTANCE: in three-phase current motor the control of rotor speed is achieved only by combination of supply current phase windings located on two pairs of stator poles so that three-phase motor is changed into two-phase motor, with shift through 90 electric degrees between magnetic fluxes of pairs of poles, the control of rotation speed of which is performed by changing the voltage value on windings of one of the pole pairs. ^ EFFECT: smooth mechanical regulation of processes in wide range. ^ 4 dwg |
