Question
The current a motor draws at start up before the motor starts to turn is known as ________
a. FLV
b. FLA
c. LRV
d. LRA
Solution
The current a motor draws at start up before the motor starts to turn is known as d. LRA (Locked Rotor Amperage). This term refers to the maximum amount of current that occurs when the motor is unable to turn, which typically happens during startup or stall conditions. Here’s a breakdown of the relevant terms:
-
FLV (Full Load Voltage): This refers to the voltage at which the motor operates at full load.
-
FLA (Full Load Amperage): This describes the current drawn by the motor when it operates at its rated load.
-
LRV (Locked Rotor Voltage): This is not a standard term related to motor starting current.
-
LRA (Locked Rotor Amperage): This is the correct term for the current drawn by the motor when the rotor is locked and not turning.
In summary, the answer is LRA, indicating the current drawn when a motor is started but not yet rotating.
