What does the compressor LRA mean?

Is the locked-rotor current, that is, the locked-rotor current.

Lock rotor current:

1. Fix the motor rotor shaft with the motor housing by external force, and then power on the motor. At this time, the motor does not rotate at all. At this time, the current of the motor is figuratively called "locked-rotor current", or the locked-rotor current can be measured by braking the shaft end after the motor rotates.

2. This measurement is used to test the low-speed starting performance and starting torque of the motor, which is larger for AC /DC series motors.

3. The measurement time should be very short, which will overheat or even burn the motor and power supply or power supply line for a long time.
