What is locked rotor current?
"Locked Rotor Current" also called LRA which stands for Locked Rotor Amps, is commonly found on electric motor nameplates. 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 switched on, it is not turning, and draws the maximum current. As the motor starts to turn, the current goes down. This required energy is much greater than the Full Load Amps or Running Amps, which is the current drawn when the motor is running at normal speed under full load. The current required to start the motor will depend on the type of motor as well as the specified design voltage required for the motor, typically the higher the voltage, the lower the required amperage or current. The term also applies to equipment such as Air Conditioners which have an enclosed motor inside the compressor, as well as the condenser fan(s) etc. Depending on the type of motor, LR current can be anywhere from 3 to 8 times the normal running current, also called RLA, or running load amps.
Why the no-load current of an induction motor is high compared to a transformer?
Because of the presence of the air-gap between stator and rotor in motor the magnetization current is much higher than that of a transformer in addition to the friction and windage losses due to the rotation of the rotor.
Can you run 125v air conditioner on 120v house current?
Yes ,it's the same voltage.You have a +-5% of voltage range
What is the effect of increasing the length of the air gap in an induction motor?
The magnetic flux that couples the rotor to the stator will weaken significantly reducing the motor's torque.
What is the electrical load for a five ton Air Conditioner?
12 kw
How many locked rotor amps does a dual phase 4 ton air conditioner pull?
5
Where can one find air conditioner parts?
You can find air conditioner parts to replace the old ones on your current air conditioner in an electronic store (or where you bought your air conditioner) or on the internet.
Why does a Chrysler town and country stall when air conditioner is on?
check to see if a/c compressor is locked up.

Why does your car stall when air conditioner is on?
It sounds like you have a locked up a/c compressor or a bad a/c clutch..........
Why would your 2001 town and country die when you turn on the air conditioner?
This would indicate that the a/c compressor has locked up.....
Are there air conditioners in India?
Yes. One of my current students worked as an air conditioner installer before moving to Canada.
1990 ford aerostar makes loud noise when started?
Loud noise is not a good description. If its a loud squeal turn the air conditioner or defroster off. If the squeals goes away the compressor or the clutch for the air conditioner compressor is locked up.
What amps should a 5 ton rheem air conditioner pull when it starts?
Read the tag on the condenser, it will be noted as LRA. Be sure to check the LRA for the fan as well and add them together for the total. If it is not listed on the tag it will certainly be listed seperately on both the compressor and the fan motor. LRA = Locked Rotor Amps.
Why does my central air conditioner not cool my bedroom?
it probably doesnt make a convectional current around the room.
Your york air conditioner will not come on it makes a humming sound for a minute then stop?
The York Air Conditioner that will not come on after it makes a humming sound then stops might have an issue with the electrical current going to the machine. It is possible that the fan is also the culprit. The fan has to come on before the air conditioner can operate properly.
What is the definition of air conditioner?
The word, 'air conditioner' is a noun. The definition of air conditioner is a machine that controls the humidity and temperature of the air.
