Implementing a 3-Phase Brushless Direct Current Motor Drive
News & Analysis 12/2/2004 Post a comment
Brushless dc motors have a straight-line, speed-torque curve similar to that of their mechanically commutated counterparts. BLDC motor internals consist of a multi-pole permanent magnet rotor and a stator with multiple coils linked together using a triangle or star connection. Cypress engineers offer the sequencing codes for driving brushless motors with Hall Effect sensors and an analog controller.
