APPARATUS FOR CONTROLLING THE SPEED OF LINE-START-PERMANENT-MAGNET MOTOR USING AN INVERTER, CAPABLE OF CONTROLLING THE ROTATION NUMBER OF THE MOTOR BY CONVERTING THE FREQUENCY OF OUTPUTTED POWER

摘要

PURPOSE: An apparatus for controlling the speed of line-start-permanent-magnet(LSPM) motor using an inverter is provided to improve the efficiency and the mobility using power with three-phases forming balanced magnetic field.;CONSTITUTION: Input power source(21) applies power with a single phase. An inverter(23) converts the power with the single phase into power with three-phases. An LSPM motor(10) is driven based on the outputted power with the three-phases. The LSPM motor includes a stator and a rotor which is installed in the stator. A controller(27) converts the frequency of the power from the inverter in order to control the speed of the LSPM motor.;COPYRIGHT KIPO 2011
