As an electric motor’s rotor turns in close proximity to the motor windings, a bucking voltage or back electromotive force (EMF) is generated. The back EMF (BEMF) generated across the start winding is ...

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 ...

Relays and contactors use a variety of technologies to switch signals and power connections. Many devices called relays use similar techniques and topologies, but the terminology can be confusing.

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 ...

Motor protection relays are used in HVAC systems to control fan motors of the condenser, evaporator, cooling tower motor, and compressor motors. Therefore, the growth of the global motor protection ...

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).

Due to the wide variety characteristics of the induction motor, it plays the premier role in the industrial sector. Some of those are self starting, rugged construction, high efficiency, good power ...
