Overheating is a result of too much current flowing. AC motors are constant power devices, meaning they require the same amount of power to spin under a specific load. Power is equivalent to voltage times current. If voltage to a motor sags, the motor will attempt to make up the lack of voltage with an increase in current so the power stays the same. If voltage sags too much, the motor will overheat.

What causes the overheating of commutator in dc motor?
brush friction, poor ventillation, excessive sparking caused by high voltage
Why is it dangerous of overheating cables?
overheating cables can cause the insulation and other wires to melt and this removes dangerous fumes. this can also lead to a fire or an explosion.By: Aleeq Salim
How do you fix a b809d generator with under voltage problems?
AC card have over/under voltage adjustment for fault. If voltage drop to that range it will trip the fault. Also the unit have voltage adjustment in the bottom right. Voltage coming out of the cable vs voltage coming out Underwood can be different.
What cause the voltage drop in shunt generator when its loaded?
because the voltage likes to drop
What would cause high voltage drop readings?
High resistance on the feeder to the load will cause voltage drop at the load end of the circuit. If this is happening, do the calculations for voltage drop, using the amperage of the load, voltage of the load, the size of the wire feeding the load and the distance from the distribution panel to the load.
What would cause a varistor to burn?
Overload - excess voltage causes excess current, and the combination causes excess power dissipation, leading to overheating. If the varistor was included to help dampen voltage surges, then a very "dirty" supply. with large numbers of surges, can lead to overheating.
Why is your Jeep Wrangler overheating?
There are many reasons why a Jeep Wrangler is overheating. A leak in the radiator system will cause overheating. Too much pressure in the engine can cause overheating. A bad water pump or thermostat could cause overheating. The transmission can also cause overheating if it is leaking.
What is the overheating voltage of an electric motor?
Motors overheat due to excessive current, not necessarily voltage. Normal voltage can cause a motor to overheat if it is stuck (not spinning). The problem is not usually the voltage, but whatever is causing excessive current flow (usually because the motor is not spinning like it is supposed to).
Can a blown fuse cause your AC fan to not work and cause overheating to the engine?
Yes, because it will cause your fan to not work at all therefore cause the overheating.
What would the cause be of white smoke coming from under the hood of a 2003 Ford Focus SE?
The car could be overheating or have a coolant leak.
Can the knock sensor cause overheating and loss of anti-freeze?
Overheating, yes. Loss of antifreeze, no.
Could your radiator be the cause of your overheating?
yes it can
Can overheating cause my cat to get sick?
Overheating can cause a cat to get sick. The best thing you can do for the cat is to help him keep cool and give him plenty of water.
What could cause overheating in a Nissan Frontier when the air conditioning is turned on?
A bad thermostat can cause overheating in a Nissan Frontier when the air conditioning is turned on. A bad compressor can also cause this.
Could overheating on a 1994 jeep grande Cherokee Loredo cause the overdrive to not work?
Overheating the engine shouldn't effect the transmission. Overheating the transmission could.
Will a radiator leak cause overheating?
Yes! Also a good flush will improve its performance. And may stop the overheating.
What can cause the white smoke on your BMW?
overheating of the engine.
