【正文】 l as three 32bit dedicated hardware resources, such as counting unit. 2. Power circuit Drive circuit from the diode rectifier bridge, filter capacitor and the IGBT inverter constituted。s ADSP21992 chip highspeed brushless DC motor control system, which has a highspeed, high load moment of inertia, have greater motor starting torque characteristics. DSPbased motor control system with the traditional singlechip motor control system and a dedicated chip motor control system, that is, a dedicated motor control mechanisms, userprogrammable, scalable, and powerful, and so on。BLDCM BLDCM small size, light weight, it has a DC motor similar to the general good speed performance, without the existence of machinery for the device, electromagic interference noise and small, low maintenance requirements, reliability, good。 and as a result of not required excitation power, efficiency is relatively high, it has been rapid development. A pany based on ADI39。 at the same time, overe their respective shortings, such as peripherals and memory integrated into the chip to reduce circuit board area, reducing the number of system ponents to improve the CPU processing capacity, improve system reliability. System, the ultimate aim is the application of highspeed flywheel system brushless DC motor, therefore, very high speed processors, from the realtime performance to consider, Need to select the highest possible processing speed of the chip. 2199x series and ADI39。 drive circuit using IR39。 isolated part of the use of highspeed optocoupler HCPL4504, isolation from the role of potential. 3. Rotor position and current detection circuit Due to current highspeed motor, backEMF waveform distortion is more seri
