INTRODUCTION
The Needs for VSDMatch the speed of a drive to the process requirement Match the torque of a drive to the process requirementsSave energy and improve efficiency
Fundamental Principles
Rotational Acceleration
Acc & Dec in Forward Direction
Acc.& Dec. In Reverse Direction
Power & Energy
Torque & Moment of Inertia
Transformation from Rotational to Linear motion
Four Quadrant Operation
Torque-speed curves for a Motor car
Types of VSD
(a) Typical mechanical VSD with an AC motor as the prime mover; (b) Typical hydraulic VSD with an AC motor as the prime mover; (c) Typical electromagnetic coupling or Eddy Current coupling; (d) Typical electrical VSD with a DC motor and DC voltage converter; (e) Typical electrical VSD with an AC motor and AC frequency converter; (f) Typical slip energy recovery system or static Kramer system;
