The electrical insulation system for wires used in generators, electric motors, transformers, and other wire-wound electrical components is divided into different classes by temperature and temperature rise. The electrical insulation system is sometimes referred to as insulation class or thermal classification. The different classes are defined ...
v. t. e. The thermoelectric effect is the direct conversion of temperature differences to electric voltage and vice versa via a thermocouple. [ 1] A thermoelectric device creates a voltage when there is a different temperature on each side. Conversely, when a voltage is applied to it, heat is transferred from one side to the other, creating a ...
Motor velocity constant, back EMF constant. is the motor velocity, or motor speed, [ 2] constant (not to be confused with kV, the symbol for kilovolt ), measured in revolutions per minute (RPM) per volt or radians per volt second, rad/V·s: [ 3] The rating of a brushless motor is the ratio of the motor's unloaded rotational speed (measured in ...
An operating temperature is the allowable temperature range of the local ambient environment at which an electrical or mechanical device operates. The device will operate effectively within a specified temperature range which varies based on the device function and application context, and ranges from the minimum operating temperature to the maximum operating temperature (or peak operating ...
Stator. Stator of a brushless DC motor from computer cooler fan. The stator is the stationary part of a rotary system, [ 1] found in electric generators, electric motors, sirens, mud motors, or biological rotors (such as bacterial flagella or ATP synthase ). Energy flows through a stator to or from the rotating component of the system, the rotor.

t. e. In thermodynamics, a temperature–entropy ( T–s) diagram is a thermodynamic diagram used to visualize changes to temperature ( T ) and specific entropy ( s) during a thermodynamic process or cycle as the graph of a curve. It is a useful and common tool, particularly because it helps to visualize the heat transfer during a process.
Electronic properties of graphene. Sigma and pi bonds in graphene. Sigma bonds result from an overlap of sp 2 hybrid orbitals, whereas pi bonds emerge from tunneling between the protruding p z orbitals. For clarity, only one p z orbital is shown with its three nearest neighbors. Graphene is a semimetal whose conduction and valence bands meet at ...
