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
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.
Derating of a motor refers to the practice of operating the motor at a lower capacity than its maximum rated load to enhance reliability and longevity. This adjustment can account for various factors such as higher ambient temperatures, frequent starts and stops, or specific application requirements. By derating, the motor is less likely to overheat and experience premature failure, ultimately ensuring better performance and efficiency in demanding conditions.
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).
Two reasons could be that the motor was wired incorrectly or the load that the motor is driving is too heavy for the HP of the motor.
Yes, a bad AC bearing can cause a motor to overheat. When the bearing is worn or damaged, it increases friction and resistance, making the motor work harder to operate. This additional strain leads to higher temperatures, potentially damaging the motor and other components if not addressed promptly. Regular maintenance can help prevent such issues.
more than likely u fried the starter solenoid

Friction
On the 1976 model, 85 hp Evinrude, the overheat circuit is the only alarm system on the engine. Check the temperature on each head, due to independent thermostats, for an overheat condition.
No
It will overheat at idle.It will overheat at idle.
More than likely the cooling fan is not working. Can be a blown fuse, defective fan motor, or defective temperature sensor relay.
no However, you will very likely be fined for speeding, for not knowing what speed you are going without a speedometer!
No, running a motor designed for 60Hz at 8Hz would likely cause it to overheat and potentially be damaged due to insufficient cooling and reduced electrical frequency. It is not recommended to operate a motor outside of its specified frequency range.
yes it doesent
You need to take it to a Repair shop and have them scan the computor. A lean condition will cause it and will also damage the catalytic converter.
