Cooling Fan - Brushless DC Motor
Jan 05 , 2022
Motors that power ventilation cooling fans are usually divided into brushless motors or induction motors. Brushless motors are sometimes called electronically commutated motors. Commutation refers to the act of switching the electrical connection from one motor winding to the next one. Motor windings in the DC cooling fan motor is generally located in the stator or stationary portion of the ...
