Permanent magnet motors consist of two main types. Surface permanent magnet motors (SPM) and internal permanent magnet (IPM) motors. The main difference is that SPM motors place the magnets on the outside of the rotor while IPM motors place their magnets inside the motor. Benefits to internal magnets include structural integrity and reducing ...
Dry chemical powder is used on all classes of fires. Dry chemical powder puts out the fire by coating the burning material with a thin layer of dust, thereby separating the fuel from the oxygen in the air. The powder also works to interrupt the chemical reaction of fire, so these extinguishers are extremely effective at putting out the fire.
An electropermanent magnet or EPM is a type of permanent magnet in which the external magnetic field can be switched on or off by a pulse of electric current in a wire winding around part of the magnet. The magnet consists of two sections, one of "hard" (high coercivity) magnetic material and one of "soft" (low coercivity) material. The ...
CO 2 extinguisher Fire extinguisher that releases carbon dioxide gas to displace oxygen to smother and cool a fire, such as a flammable liquid. Combination nozzle A low pressure fog nozzle (usually 120 to 150 lbf/in² or 820 to 1030 kPa that can be adjusted to produce a near straight stream. Also commonly referred to as a Taskforce tip (TFT).
Monoammonium phosphate, also known as ABC dry chemical, tri-class, or multipurpose, is used on class A, B and C fires. It receives its class A rating from the agent's ability to melt and flow at 374 °F (190 °C) [27] to smother the fire. It is more corrosive than other dry chemical agents and is pale yellow in color. Sodium bicarbonate ...
