Heat Loss from Electrical Motors

(10 kW) (150 watts/kW) = 1500 watts = 1.5 kW. The rest of the energy (10 kW) - (1.5kW) = 8.5 kW. is output mechanical energy. If the motor and the mechanical equipment connected to the motor is in the same room - or enclosure - all electric energy supplied to the motor will convert to heat and temperature increase in the room.

Best Motor for DIY Wind Turbines: The Ultimate Guide

Aug 18, 2021Our small 5 Watt wind generator is not able to power a house. However, we are currently preparing another DIY project - a 100 watt Wind Turbine. In combination with the right battery bank, 100 watts can easily power a TV, LED bulb, and a laptop. As a generator core, we will use a stepper motor again, but this time from an old A3 dot-matrix printer.
