1 The Brushless_Motor_in_Activate_Relax_States (BMARS) designed in this paper is a computer brushless DC fan modified into the BMARS to operate in harsh environment, where integrated circuits are forbidden to be operated, such as to tolerate some presence of water. And to operate in high temperature ranges similar to electrical transformers. BMARS is presented as a coil of an electrical rotating machine. The coil terminals are operated in two time intervals composed of activated time interval then relaxed time interval. The coil terminals are activated in electrical power by transistors during a time interval and followed by a High Impedance State of the transistors allowing the extraction of coil signal in relaxed mode to permit to impose the right polarity of electrical power into the coil on the next time instant to result in a rotating motor.
