| Abstract |
Generally, Permanent Magnet Brushless DC Motor(PM BLDC) is necessary the Hall-IC to detect the rotor position. But it will take place the operation standstill of motor or error of rotor position detection according to the circumference temperature, humidity, or limited surroundings. This paper propose the algorithm of rotor position detection only using one or two Hall-IC. Therefore we can estimate information of the others phase in sequence through a rotor instead of using three Hall-IC at 3 phase motor. This paper identify the same characteristics, performance, and function of protection circuit by the proposed algorithm with the 3 phase PM BLDC motor in comparison with general method. |
