Stepper motors use specialized control methods to achieve better precision than standard variable speed motors, while avoiding the expense and complexity of servo systems. For industrial automation, the term motion control usually means using an electric motor to positively drive the position, velocity, and acceleration of a physical system. Pneumatics are economical, and hydraulics can…
There are many safety devices available to ensure machine safety and to detect personnel entering unsafe areas. Cable pull switches, safety light curtains and interlock switches (non-contact and the many types of tongue interlock switches) are just a few of them. Most of you have probably heard of, or used, these devices in some capacity,…
