brushless dc motor is relative to the brush motor. With brush motor rotor winding, and the power output shaft is linked together, the stator is permanent magnet steel; Brushless dc motor rotor is a permanent magnet steel, along with shell and output axis is linked together, the stator is winding coil, to remove a brush motor commutator brush to alternating electromagnetic field, so it is called brushless motor. （1)Electromagnetic position sensor used in brushless dc motor is much more open transformer. Used for three-phase brushless dc motor tracking open transformer by the stator and rotor of two parts. 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 to accompany the motor rotor rotating bezel and stationary sources, photocell parts, etc. The motor, brushless motor is comprehensive, microelectronics, control and computer technology in one high-tech product. Brushless motor 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 is bound to more rapidly. Combined with position sensor detecting motor rotor polarity anytime and anywhere, is more advantageous to fully use and maintain good brushless motor. Brand brushless motor technology is committed to research and development costs are lower, simple installation, signal processing better brushless motor and position sensor products, related information and the newsletter can be focused on the mechanical and electrical equipment co. , LTD.
