Death with positive Feedback and Negative Feedback loop control system, if the Feedback signal, in contrast to the given value signal, it is called a Negative Feedback (Negative Feedback), fan motor stator winding if the polarity is the same, three phase motor it is called a positive Feedback, generally infinite loop control system adopts Negative Feedback, also called Negative Feedback control system. Examples of many infinite loop control system. Such as a person is the death of the one who has a negative generator feedback loop control system, the Electric motor eye is the sensor, ACTS electric motor low rpm as the permanent magnet motors for sale feedback, the human body system by constantly modified finally made magnetic generator of correct action. If without www.dongfeng-motor.com eyes, there is no feedback loop, has become an open loop control system. Another example, when a real full-automatic washing machine is can single phase 2hp electric motor check whether clothes washed in a row, and can automatically cut off the power supply after the wash, it is an infinite loop control system.
