Many single-phase motors used with refrigeration-duty, semi-hermetic and hermetic compressors require an external relay to assist in starting. How much do you know about these necessary products? An ...

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 ...

[Nothinglabs] built this motor controller as an alternative to using an H-bridge. They call it the RAT controller which stands for “Relay and Transistors”. You can see above that two Darlington ...

Carlo Gavazzi is pleased to announce their new DTA7 Series of Motor Thermistor Relays. They are capable of monitoring the temperature of up to six motors (via thermistors on the internal windings).

ICM Controls will showcase its new Universal Motor Starting Relays (UMSR). The UMSR is a wire-for-wire replacement for all standard potential relays that operate a single-phase motor with a voltage ...

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 ...

A reversible DC motor can be controlled to spin clockwise and counterclockwise using this circuit which only has a single switch for single control signal. A reversible DC motor can be controlled to ...

If you work on cars you’ve probably heard of relays; in fact, we often cover using relays in our tech articles. Following detailed instructions to wire one can work, but understanding what makes them ...
