  • Control Of Motors That Do Not Use Commutators (AREA)

Abstract

PURPOSE: To control the leading angle of inverter so as to keep the DC output voltage of the converter constant, resulting in that the motor is operated at a stable and high power-factor without use of a power-factor improving condenser which is large-sized and costly.
