METHOD FOR STARTING ELECTRIC MOTOR DRIVING TO ROTATION NON-BALANCED ROTOR

摘要

controlling electric motor operation for driving non-balanced rotor of vibration type and other machines used in mining, at manufacturing building materials and other industry branches. SUBSTANCE: rotor rotation is started by exciting reverse-rotary oscillations with increased angular amplitude. It is provided due to multiple energizing of electric motor according to signals of pickup detecting rotor revolution number. EFFECT: reduced starting torque and consumed power of electric motor. 1 dwg
