ELECTRIC-MOTOR HARMONIC CURRENT ATTENUATION DEVICE

摘要

electrical engineering. SUBSTANCE: device depends for its operation on controlling rotational frequency of motor by variation between sine-wave and nonsinusoidal-wave voltages due to phase control of sine-wave voltage. It has reactor with E-shaped wound core and I-shaped core. EFFECT: improved reliability. 10 cl, 10 dwg, 6 tbl
