What is the purpose of the internal overload protector in the compressor motor?
No
Why is there a delay in re-starting a compressor that has kicked off an internal overload?
an internal overload is based off of heat.High heat=overload opens.Heat has to dissapate and motor cool to safe temp before internal contacts will close.
What is the conclusion of overheat protection of induction motor?
If the overload protection is set correctly to the motors full load amperage, any overloading of the motor will trip the protection and take the motor off line. Once the reason of the overload has been established and rectified, the overload protection is reset and the motor can be brought back on line.
A device with a overload protection used to control a motor is a?
A device with an overload protection used to control a motor is an Overload Relay.
What is wrong if your AC blows cool for about a minute and then the outside shuts off and the fan just blows hot air?
It could be any one of the following: 1. The fan motor is overheating and is shutting down on overload, which will cause the compressor to shut down via the high pressure switch. 2. The compressor is getting too hot and is shutting down via the thermal overload switch. You need to determine if the fan and the compressor both come on at the outdoor unit. If you are getting cold air inside the house, the compressor is probably running. It generally takes longer than 1 minute for the fan to go out on overload unless the bearings are shot, then the fan motor could seize up and shut the compressor down on overload. You should have this checked by an HVAC tech.
What kind of single phase motor would most likely be used to drive a refrigeration compressor?
I would use a totally enclosed motor.
What would cause a 240V motor to surge?
Your air compressor drive belt is loose, Tighten it up! geterdone
What is a heater overload?
overload heater is used to protect a large electric motor. If the overload heater get too hot from excessive current. its nomally-closed overload contacts wil open. interruptting the circiut of powe supply of motor
How do you set motor amp overload?
There are many types of overload protection these days and all are based on the FLA (full load amps) of the motor.
What are the calculation for overload relay for three phase motor?
If a motor 3 phase or single phase goes above the full load amps that is on the nameplate of the motor then it is in overload condition. This is usually caused by trying to drive machinery with less horsepower that the manufacturer recommends To protect the motor from this condition overload heaters are put in series with the supply voltage and the motor leads. If the current from the motor draws more that the motor's nameplate FLA then the overload heater opens the supply voltage through use of a motor contactor. The contactor can not be closed again until the motor overload heaters cool down and by the same token the motor gets a chance to cool down. This condition is rectified by either using a bigger HP rated motor or lowering the load on the machinery that the motor is driving.
What is the difference between a fuse and a time delay fuse?
A time delay fuse will not blow at the first sign of an overload. It will delay blowing just long enough to allow a motor to start or a compressor to startup.
How you can solve the problem for one of a dc motor that connected to pulse width modulation and this motor didn't start?
check the brushes if you are getting dc out of the drive and the motor doesnt start the motor should also have full field to start with an extreme overload even a permanent magnet can be discharged or reversed this is assuming the pwm drive is ok
