To calculate the LRA (Locked Rotor Amperage) of a three-phase compressor in terms of tonnage, you can use the formula: Tonnage = (LRA × Voltage) / (1.732 × Efficiency × 12,000). Here, 1.732 represents the square root of 3, and 12,000 is the conversion factor for BTUs to tons. Ensure you have the correct voltage and efficiency values for accurate calculations. This approach provides an estimate of the cooling capacity based on the compressor's electrical characteristics.

How do you calculate LRA to tonnage in three phase?
To calculate LRA (Locked Rotor Amperes) to tonnage in a three-phase system, first determine the LRA value of the motor, usually provided on the motor nameplate. Then, use the formula: Tonnage = (LRA × Voltage × √3) / (3,517 × Efficiency × Power Factor), where the voltage is the line-to-line voltage in volts, and the efficiency and power factor are the motor's operational values. This will estimate the cooling capacity in tons based on the motor's electrical characteristics.
How do you calculate FLA from LRA?
A typical rule of thumb is FLA=LRA/6
How do you calculate LRA to BTU?
Well, honey, to calculate Locked Rotor Amps (LRA) to British Thermal Units (BTU), you'll need to first convert LRA to watts by multiplying it by the voltage. Then, divide the result by 3.41 to get the BTU per hour. It's as simple as that, darling.

How do calculate from HP to LRA?
To convert horsepower (HP) to full-load amperes (LRA), you can use the formula: LRA = (HP × 746) / (Voltage × √3) for three-phase systems, or LRA = (HP × 746) / Voltage for single-phase systems. Here, 746 is the conversion factor that represents the number of watts in one horsepower. Ensure you use the appropriate voltage based on your system to get an accurate LRA value.

Do you calculate loads from Locked rotor amp?
Yes, locked rotor amps (LRA) can be used to calculate the load on a motor when it starts. LRA represents the current drawn by the motor when the rotor is not moving, which is typically much higher than the running current. To determine the load, you can use LRA in conjunction with the motor's rated voltage and efficiency, applying appropriate safety factors. However, for precise load calculations, additional factors like the motor's application and operating conditions should also be considered.
