Locked Rotor essentially means the motor is not turning. The current or amps in this case have to do with the amount of electrical energy required to start the motor. At the instant the motor is …
Witryna20 paź 2014 · Because starting current is roughly six times nameplate current (depending on the NEMA code letter), it can be significantly higher for an oversized motor than a “right-sized” model. A motor’s actual inrush current, also known as locked-rotor amps or LRA, can be calculated from the kVA/hp values associated with its NEMA … Witryna22 cze 2024 · The main difference between starting and locked rotor amps is that the LRA does not have an output voltage.
