一种受控机电混合换向理论及无位置传感器控制

Both brushed dc motors and brushless dc motors have a wide range of applications, but mechanical commutating devices have the problem of harmful commutation arcs, and electronic commutating devices increase the cost of control systems. The uncontrolled mechanical–electronic hybrid commutating device passively controls the voltage of the freewheeling commutator segment through the capacitor, but th...
