System Block Diagrams

System block diagrams enable one to visualize the system as large interacting components that can be conceptualized and developed independently. This type of architecture also lends itself to greater flexibility and extensibility of the system, enabling it to grow and evolve more easily to adjust for changing requirements and demands.

CNC Control

CNC systems require motor drives to control both the position and the velocity of the machine axes. Each axis must be driven separately and follow the command signal generated by the NC control. There are two ways to activate the servo drives: the open-loop system and the closed-loop system.

Servo Motors for CNC Machines

2019/4/22Servo motors, also known as axis or torque motors, use fewer electromagnetic poles—usually fewer than a dozen—and rely on closed-loop communication for accuracy and speed control, meaning there is a two-way signal between it and the control. In other words, when powered on, the control receives an exact positioning signal.

Pulley Systems

Pulley systems are used to provide us with a mechanical advantage, where the amount of input effort is multiplied to exert greater forces on a load. They are typically used for hauling and lifting loads but can also be used to apply tension within a system such as in a Tensioned Line or Tyrolean. This page explains the basic principles of
