How do electric motors produce mechanical energy?

Electric motors make mechanical energy through the interaction between magnetic fields. Take two magnets and attempt to push their North poles together. There will be a repulsive force that resists this motion. read more

Motors dont produce mechanical energy but convert electrical energy to heat and mechanical energy. The portion converted to heat (through the resistance of the windings and the friction in the mechanical parts) is wasted energy as far as the motor is concerned and brings the efficiency down from 100%. read more

Assume no vibration loss, the amount of energy input to electric motor subtract out the converted 92 J of mechanical energy is the thermal energy produced. read more

First of all, a turbine alone does not produce electrical energy. A turbine is a device that uses the thermal energy (i.e. the pressure and temperature) of a working fluid, generally water in the form of steam, to produce mechanical energy. read more
