Portable space heaters are small, electric resistance heating units. Regardless of the shape, size or type of electric heating element found in an electric space heater, virtually all power drawn is converted into heat. The cost of operating an electric heater depends on how much heat the unit is delivering.ortable space heaters are small, electric resistance heating units.

Flexible electronics, also known as flex circuits, is a technology for assembling electronic circuits by mounting electronic devices on flexible plastic substrates, such as polyimide, PEEK or transparent conductive polyester film.
Brushless DC electric motor (BLDC motors, BL motors) also known as electronically commutated motors (ECMs, EC motors) are synchronous motors that are powered by a DC electric source via an integrated inverter /switching power supply, which produces an AC electric signal to drive the motor.
