The brushless DC (BLDC) motor is also referred to as an electronically commutated motor. There are no brushes on the rotor and commutation is performed electronically at certain rotor positions. The stator magnetic circuit is usually made from magnetic steel sheets. One of the recently popular brushless motor control techniques is Field Oriented Control (FOC).
NXPs broad portfolio and extensive documentation allows you to ease the development effort for BLDC control applications.
This application note describes the design of a three-phase Brushless DC (BLDC) motor drive based on NXP’s MC56F8257 digital signal controller (DSC). The application design incorporates the advantages of DSC peripherals for
"BLDC fans offer several advantages over traditional brushed DC motor and induction motors, including more torque per weight, more torque per watt (increase efficiency), high dynamic response, increased reliability, reduced noise, longer lifetime, more power and overall reduction in electromagnetic
