Practical Motion Control for Engineers and Technicians

THE WORKSHOP

This workshop is designed for personnel who need to apply motion control technology as productively and economically as possible. This practical workshop initially examines the basic building blocks and design tools to implement motion control systems. Fundamental concepts of load, inertia, force and real time will be discussed.

The various factors such as performance limitations and costs that impact the selection of electro hydraulic, pneumatic, electromechanical technologies are discussed.

Servo basics are then examined in considerable detail giving you the practical tools in which to work with these systems. The electrical and mechanical characteristics important in tying together the drive and motor to the mechanical device are then reviewed from a practical perspective.

The basic motors used in motion control such as DC and AC motors, stepper and servo motors and their applications, are also examined. These motors range from small instrumentation motors to robust AC induction motors and to the stepper motors used in open loop control.
