Position sensor applied in brushless dc motor controller

by:Hoprio     2020-07-22

brushless dc motor controller is relative to the brush 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. ( 1) Electromagnetic position sensor used in brushless dc motor controller is much more open 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 ( 2) Magnetic susceptibility type 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. Photoelectric ( 3) 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 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. With the development of power electronics and the emergence of new permanent magnet materials, the development of brushless dc motor controller will more rapidly. Combined with position sensor detecting rotor motor controller polarity anytime and anywhere, more conducive to full use and safeguard the brushless motor controller. Brand brushless motor controller technology is committed to research and development costs are lower, simple installation, signal processing and better brushless motor controller and position sensor products, related information and the newsletter can be focused on the mechanical and electrical equipment co. , LTD. http://www。 tcmotor。 com/
