A common "Permanent Magnet Brushless DC" (PM BLDC) motor consists of a 3-phase coil wound on a cylindrical shaped magnetic core (the STATOR) and a rotor/shaft assembly which is normally held in place by bearings which mount at either end of the stator. BLDC motor fed by six step inverter for desktop CNC machine investigated. Motor has 3 phases, 0.0089 kg/m2 /0.00091 kg/m2 changes inertia moment, 0.005 viscous. The stator of a brushless DC motor is equipped with a polyphase winding. The phases are connected to the DC bus through a switching circuit. The switching sequence is The high gain converter is controlled using an outer speed loop and an inner current loop to regulate the DC link voltage of the BLDC with a six-step inverter. A comparative study of the Boost converter-fed brushless DC motor and the high-gain converter-fed BLDC motor is carried out. The permanent magnet brushless DC motor (BLDCM) is typically controlled using the six-step commutation method, and the flux-weakening method is employed to enable the motor to operate at speeds higher than the base speed. Currently, it is considered that the weak magnetic angle range is 0-pi/3, while the range for deep weakening is pi/3-pi/2.
