CHAPTER ONE: GENERAL
1.1.Overview
The Glentek Inc. SMB9675-1A-1-6889 vector drive uses flux vector technology to close
a torque (current) feedback loop. When applied to a three phase induction motor,
the result is servo motor like performance from a standard three phase induction
motor. The Digital Signal Processor (DSP) based vector drive uses it’s high speed
math processing capability to continuously calculate flux and torque vectors and to
maintain a constant 90 degree phase difference between the vectors. This technique
allows torque control from zero speed to base speed and above. Encoder feedback
provides the shaft position data needed to calculate the vectors and velocity data, thus,
Vector Control allows precise speed control down to and including zero speed of an
induction motor.
1.2.Intended Application
