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 ...

Single-phase motors are common in many industries and can be found in blowers, pumps, fans, lathes, and numerous other types of equipment. Single-phase motor failures or malfunctions can often be ...

The motor calculations presented here apply to changing conditions of a blower motor when pulley adjustments are made. However, these calculations are useful wherever electric motors are used. These ...

These motor drive analyzers simplify troubleshooting on single-phase and three-phase motor-drive systems by providing guided testing that enables technicians to quickly capture the most important ...

When motors start across the line, they typically draw five times the running current. This temporary “inrush” is an overload condition. To handle inrush while still providing adequate overcurrent ...
