The load of the motor itself is constant and it will try to achieve it's running RPM. If the supply voltage decreases the amperage needed increases to where the motor windings cannot sustain the current flow without producing excessive heat. Hence, SMOKE!
what makes a electric motor get very hot and then shutoff after 20 seconds
You can generate electricity with a 27KVA alternator, a big wheel, and a 2HP motor, but you will not be able to even come close to generating 27KVA. The best you could hope for is about 1KVA or so, because a 2HP motor can only do about 1.5KW of work, and efficiency and power factor losses will make the output be even less.
Electric motor.
An electric motor converts electrical energy to kinetic energy.
In order for an electric motor to spin freely you will have to make sure you have one thing. You have to have the electric current for the motor to run freely.

enough oil is what you need
The ratio is 50:1.
It would depend on the efficiency and design of the motor, as well as the operating conditions such as load distribution and friction. In general, a 2HP 4-pole motor may not have enough torque to lift 300kg vertically, but it could potentially move the weight horizontally on wheels or a conveyor. It's important to consider the motor's continuous duty rating and consult with a mechanical engineer for a more accurate assessment.
Find the amperage that your pump motor operates on (should be on the motor nameplate) and multiply it by the voltage that the motor is connected to (120 or 240 volts). This will give you the wattage of the motor. It is usage of watts that the utility company bills you on. Find from your utility bill what you are charged per kilowatt hour. Take your pump wattage, times the amount of time that the pump runs, times the kilowatt rate you are charged by the utility company and the result will be how much it costs you to run the pump motor.
i have 7.5kw dynmo and 2hp motor the motor attach with home electicity and dynmo show 225 watt but not working dynmo to motor i dont no tell me plz
well the motor will like it, it will run cool but the power bill will be high. it will not have the flow of a 2hp impeller
The motor is a 1947 2hp. Great little motors. I have two of my own.
The electric motor changes electric energy into mechanical energy.
