Stepper motors are useful for relatively low-speed, intermediate-torque drive and positioning applications, particularly where accurate sub-revolution rotor position control is necessary. Motors of ...

In this chapter, I will present a few useful “cookbook” applications for real-time control circuits designed to perform some specific low-level task and interface with a master controller for ...

Higher Capabilities for Safety-Rated Control Circuits A truly reliable safety control system must work even when some parts fail. Force-guided relays are unseen components that add another level of ...

To help achieve more precise control of gene therapy, engineers have designed a new control circuit that can keep gene expression levels within a target range. The method could be used to deliver ...

Per 2014 NEC Article 100, short circuit current rating (SCCR) is defined as: “The prospective symmetrical fault current at a nominal voltage to which an apparatus or system is able to be connected ...

Circuit protection has proven useful, but meeting the increasingly sophisticated industrial and commercial requirements can be a challenge. An overload or short circuit in a fuse or mini circuit ...
