Single-phase and 3-phase AC squirrel cage induction motors need some type of control circuit to initiate a start or stop function. The two types of ladder control circuits commonly used are the 2-wire ...

When you get the call, “The motor won’t start,” you’d best have a logical and systematic plan in place to approach the problem. “Easter egging” just doesn’t work unless you happen to be very lucky!

The proper selection of 3-phase solid state relays for motor control application depends not only upon a comprehensive understanding of 3-phase SSRs, but also of the 3-phase power system and typical ...

Most industrial facilities include electric motors that require overload relays for protection, control and monitoring purposes. The latest overload relays are often called motor management relays ...

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 ...

AutomationDirect has added new motor control, phase monitor, alternating, pump seal, and intrinsically safe relays to its collection of relays. ProSense motor control relays from AutomationDirect ...
