Wireless power transfer (WPT; also wireless energy transmission or WET) is the transmission of electrical energy without wires as a physical link. In a wireless power transmission system, an electrically powered transmitter device generates a time-varying electromagnetic field that transmits power across space to a receiver device; the receiver ...
Electric fan heater. A fan heater, also called a blow heater, is a heater that works by using a fan to pass air over a heat source (e.g. a heating element). [1] This heats up the air, which then leaves the heater, warming up the surrounding room. They can heat an enclosed space such as a room faster than a heater without a fan, [2] but like any ...
The motor used a two-pole brushless rotor with a digital controller. Dyson said its efficiency was 84%, which was less than the 96% efficiency that is achieved in some brushless designs. [citation needed] In order to deal with the high speed and centrifugal forces, the impeller is made of carbon fibre reinforced polymer; the shaft is steel. [3]
Inductive charging (also known as wireless charging or cordless charging) is a type of wireless power transfer. It uses electromagnetic induction to provide electricity to portable devices. Inductive charging is also used in vehicles, power tools, electric toothbrushes, and medical devices.
Kitchens and bathrooms typically have mechanical exhausts to control odors and sometimes humidity. Factors in the design of such systems include the flow rate (which is a function of the fan speed and exhaust vent size) and noise level. Direct drive fans are available for many applications and can reduce maintenance needs.
A household electric fan A large cylindrical fan. A fan is a powered machine that creates airflow. A fan consists of rotating vanes or blades, generally made of wood, plastic, or metal, which act on the air. The rotating assembly of blades and hub is known as an impeller, rotor, or runner. Usually, it is contained within some form of housing ...
