Energy conservation issues in countries around the world continue to be taken seriously, the US EPRI noted that the amount of global motor consuming up to 95 billion dollars a year, accounting for 51% of all electricity. Whether it is industrial, domestic and commercial electricity, electrical energy is consumed high proportion. If the system is to improve the output of the motor, the input power ratio, it can improve the efficiency of electricity. The brushless DC motor with high efficiency, control features, high reliability, long life, low noise, more and more home appliances are replaced by an AC motor. Compared with traditional AC motors, DC motors efficiency has improved significantly, especially in the low speed range can be high-efficiency operation, improving system energy efficiency.

   For energy saving trend of globalization, WPG WPI launched NXP, Toshiba microprocessor brushless DC motor control scheme is designed to provide more rapid, simple motor control scheme for high precision and high flexibility.
