What's the position sensor brushless dc motor controller for? Along with the development of the industry and the emergence of new permanent magnet materials, brushless dc motor controller has been widely used, the brushless dc motor controller has the characteristics of a dc motor controller, as well as the frequency change device, so also known as the dc inverter, international general nouns denote for BLDC. MotorsFriends who use brushless dc motor controller for position sensor will not be unfamiliar. So what's the position sensor brushless dc motor controller for? The principle of how again? Below by shenzhen ding hong factory staff to introduce: brushless dc motor controller is relative to the motor of the controller. There is motor controller of the rotor coil winding, and the power output shaft is linked together, the stator is permanent magnet steel; Rotor brushless dc motor controller is permanent magnet steel, along with shell and output axis is linked together, the stator is winding coil, to remove a brush motor controller used for alternating electromagnetic field commutator brush, so called the brushless motor controller. Position sensor in brushless dc motor controller plays a role that can locate the position of the rotor magnetic pole, to provide the correct logical switch circuit in the phase information, the rotor magnetic pole position signal into electrical signal, and then to control the phase of the stator winding. Position sensor sort is more, and each has its characteristics. State manufacturer brand extension brushless motor controller of brushless dc motor controller position sensor has the following three kinds of commonly used, respectively is magnetic sensors, magnetic susceptibility type location proximity sensors, photoelectric position sensor. 1, the magnetic position sensor in brushless dc motor controller, use morer is open the transformer. Used for three-phase brushless dc motor controller opening transformer consists of two parts, rotor stator and tracking. Stator generally there are six pole, the interval between them is 60 degrees respectively, three of them in a winding around, and in series with high frequency power supply, after another three pole respectively on secondary winding around the WA, WB, WC. Magnetic susceptibility type 2, magnetic susceptibility pattern position sensor is to point to some of its electrical parameters change with the surrounding magnetic field according to certain rule semiconductor sensitive elements. The basic principle of hall effect and the magnetic resistance effect. Common magnetic sensor with hall element or hall integrated circuit, magnetic sensitive resistor and magnetic susceptibility diode, etc. 3, photoelectric photoelectric position sensor is made use of the photoelectric effect, by following the rotor motor controller with rotating bezel and stationary sources, photocell parts, etc. Brushless dc motor controller is a combination of motor controller, microelectronics, control and computer technology in one high-tech product. Brushless motor controller in the medical, industrial control, automotive electronics and consumer electronics and other high precision control industries widely used. The above position sensor brushless dc motor controller have what effect? Sensors detect the polarity of the rotor of motor controller anytime and anywhere is more advantageous to fully use and maintenance for brushless dc motor controller.
