| Abstract | Brushless DC motors have gained considerable commercial success in high end four quadrant servo systems, as well as in less demanding, one and two quadrant requirements. Cost sensitive four quadrant applications thus far have not fared as well. Designs which meet cost goals often suffer from poor linearity, and cumbersome protection circuits to assure reliable operation in all four quadrants. Better performance en tails more complex circuitry and the resulting additional components quickly increase size and cost. Part of the design challenge results from the lack of control ICs tailored to four quadrant applications. The other major obstacle has been implementing a reliable and cost effective high-side switch drive. With recently introduced integrated circuits in both areas, it is now possible to design a rugged, low cost, four quadrant brushless DC servo amplifier with relatively low component count and cost. |
