You need to first know the wattage of the motor and locked rotor current can be tested at a lab only
"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.
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.
Yes ,it's the same voltage.You have a +-5% of voltage range
The magnetic flux that couples the rotor to the stator will weaken significantly reducing the motor's torque.

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.
check to see if a/c compressor is locked up.
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.
It sounds like you have a locked up a/c compressor or a bad a/c clutch..........

To calculate the power consumption of an air conditioner in watts, you multiply the voltage (V) by the current (I) in amperes. The formula is: Power (W) = Voltage (V) x Current (A). You can usually find the voltage and amperage ratings on the air conditioner's label or in its manual.
This would indicate that the a/c compressor has locked up.....
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.
Yes. One of my current students worked as an air conditioner installer before moving to Canada.
A thermostat controls the temperature of an air conditioner by sensing the current temperature in a room and comparing it to the desired temperature set by the user. When the room temperature is higher than the desired temperature, the thermostat signals the air conditioner to turn on and cool the room. Once the room reaches the desired temperature, the thermostat signals the air conditioner to turn off.
it probably doesnt make a convectional current around the room.
