If the motor's shaft will not turn (is locked) because maybe its bearings have seized - up or the thing it is driving has got damaged so it won't allow the shaft to turn, the motor will overheat in short-order.

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).
When the rotor of an electric motor is jammed the coils are likely to overheat and even burn Explain why this does not happen when the rotor is not jammed?
Because work is being done by a rotating motor. The stalled motor still wants to work, but cannot. The incoming energy is turned to heat. In-depth Answer: As a motor slow down under a load its current draw increases. At stall (locked, jammed, etc) the current is maximum for the motor. At this point the motor ceases to be a motor and can be thought of as a resistor in the circuit. As the current flows through the windings they heat up and eventually the insulation fails. This, in turn, causes shorting/arcing between the coils. Under normal operation the current is low enough not to cause this effect. Most electric motors have a fan cooling system built into their housings to prevent overheat while running. Also, thermal cut offs are sometimes placed in the coils. These cut power if the temperature exceeds a certain limit.
What is a machine that turns mechanical energy into electrical energy?
Electric motor.
What operating condition is most likely to overheat a motor?
When dc motor run full torque at low speed. Armature current is high and field current is set to max to get the torque. When motor is field weaken then temperature decrease at same cooling air flow
What is output of an electric motor?
An electric motor converts electrical energy to kinetic energy.

What would cause a 240 ford motor to overheat?
A stuck or incorrectly installed thermostat.
Why is electric motor quiet?
Cause they wanna be
Can continued cranking overheat your starter motor?
more than likely u fried the starter solenoid
How clutch slippage may cause engine to overheat?
Clutch slippage can cause an engine to overheat by running the engine at higher rpm's than what it is recommended for the motor. Excessive heat in the engine can cause the head gaskets to leak building up heat in the motor. There are inexpensive kits to test whether your headgasket is leaking or not.
Why does your car overheat after adding transmission fluid?
Your motor oil going bad would cause that. That is in the crankcase, not the transmission.
What would cause a washer motor to stop working on a Hyundai Elantra?
Debris in the hoses or reservoir could cause the motor to overheat. Also, running the pump without fluid could do the same.
Would blown head gaskets cause your vehicle to overheat as soon as you drive it?
it is possible for heat from combustion to cause an engine to overheat quickly depending on where the gasket is blown, but i would look for a lack of coolant circulation first. if your coolant is not getting out of the motor and into the radiator it will overheat very quickly.
If defective blower motor draws more current than a good motor because?
defective motor will not run, also cause the blower motor speed resistor to burn out and eventually blow the fuse. a motor with defective bearings will draw excessive current causing either the fuse to blow or cause the motor to overheat

What happens when the blower motor resistor goes bad?
What can happen when a blower motor resistor goes bad is that the motor will run and then suddenly stop running on a regular basis. Sometimes the blower fan will not turn on and cause the motor to overheat.
Why would a gasoline motor overheat?
