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 ...

Potential relays are commonly found on many smaller, single-phase, capacitor-start, capacitor-run motors in the HVACR industry. Their function is to assist in starting the electric motor. Potential ...

A motor protection relay safeguards electric motors by detecting thermal stress, phase imbalance, stall, and abnormal ...

Over my almost 60 years in the auto repair industry as an ASE and GM Master Technician, and vocational education automotive technology instructor, I have seen firsthand how vehicles have evolved from ...

Use of the powerful event reports can increase system reliability, lower maintenance costs, and reduce the potential for system damage and resulting outages. Today’s microprocessor-based relays ...
