PENGENDALIAN KECEPATAN MOTOR SINKRON MAGNET PERMANEN (MSMP) TIPE INTERIOR DIATAS KECEPATAN DASAR
Abstract: This paper presents
a method to control Permanent Magnet Synchronous Motor (PMSM) at high speed
above the based speed. To control PMSM from zero speed up to base speed, the
armature voltage of the motor may be varied up to maximum voltage allowed of
the inverter used. In this region the stator voltage will increases with the
increases of motor speed reaches the based speed, motor voltage cannot increase
anymore because of saturation and consequently motor speed cannot be increase
more highly. In order motor to control the motor above base speed, it is can be
done by weakening the field flux of the rotor. As the rotor made of permanent
magnet, then filed weakening control cannot be done directly. The control of
field-weakening effect is done by controlling stator current vector of direct
axix, which is variable with speed.
