Abstract
The brushless DC motors with permanent magnets (PM-BLDC) are widely used in a miscellaneous of industrial applications. Usually, these applications are characterized by relatively high torque ripples. In this study, closed-loop speed control of PM-BLDC motor fed by six step inverter for desktop CNC machine investigated. Motor has 3 phases, 0.0089 kg/m 2 /0.00091 kg/m 2 changes inertia moment, 0.005 viscous damping, 3000 rpm reference speed, 4 poles and trapezoidal back EMF wave form. Inverter has 3 bridge arms, snubber resistance 5000 ohms, snubber capacitance 1 uF. Developed speed control PM-BLDC motor use in desktop CNC machine. Also simulated on MATLAB and results are presented in the study. DOI: http://dx.doi.org/10.5755/j01.eee.19.1.3244

Summary
Brushless DC motors with permanent magnets (PM-BLDC) are widely used in a miscellaneous of industrial applications. The permanent magnet brushless dc (BLDC) motor is gaining popularity being used in military, aerospace, computer, automotive, industrial and household products because of its high torque, compactness, and high efficiency [1], [2]. To improve the performance of BLDC motors, different control methods have been developed by many researchers. Those are such as the field weakening control method, overlapping method, PWM chopping method [6]–[11]. In this study, closed-loop speed control of PMBLDC motor fed by six step inverter for desktop CNC machine investigated. Developed speed control PM-BLDC motor use in desktop CNC machine. PM-BLDC motor which has closed-loop speed control algorithm used in CNC machine for mechatronic laboratory experiment
