www.nxp.comThree phase Brushless DC (BLDC) motors are good candidates because of their high efficiency capability and easy to drive features. The disadvantage of this kind of motor is the fact that commutation of motor phases relies on its rotor position. Although the rotor position is usually sensed by sensors, there are applications that

www.rses.orgHVAC systems is a brushless dc three-phase motor with a permanent magnet rotor. Motor phases are sequentially energized by the electronic control, powered from a single-phase supply. An ECM is actually made of two components—a motor control (the control module) and a motor (sometimes called the motor module). Depending on the style of ECM,

www.egr.unlv.edu• On large generators and motors, brushless exciters are used. • A brushless exciter is a small AC generator whose field circuits are mounted on the stator and armature circuits are mounted on the rotor shaft. • The exciter generator’s 3-phase output is rectified to DC by a 3-phase rectifier (mounted on the shaft) and fed into the

www.componentsengineering.comBrushless DC fans are usually available in four nominal voltages: 5V, 12V, 24V, and 48V. If the system has a regulated power supply with one of these voltages, then a brushless DC fan may be utilized. This fan will provide performance required, without the input variables that plague AC fans. The speed and airflow of a typical DC fan is
