Evaluation of a 6 pole axial flux PM motor for Control Moment Gyroscope Application

Ertan, Hulusi Bülent
In a previous study a compact Control Moment Gyroscope (GMC) design, based on a 6-pole, axial flux (AF) motor was presented. The GMC design in that proposal was based on analytical expressions and naturally 3-D structure of the AF motor could not be fully taken into account. In this paper the designed motor is simulated using 3-D FEM solutions. The parameters of the design such as electric loading and current loading as well as the performance of the design such as phase current and the torque produced at 10000 rpm are determined in a more realistic environment. The results indicate that the adopted analytical design approach is suitable for the design of the CMC motor. However, improvements are needed in the design methodology to reduce torque ripple and take into account the effect of the drive conditions in the operating environment.


Design of a control moment gyroscope with outer rotor BLDC motor
İnce, Berk; Ertan, Hulusi Bülent; Department of Electrical and Electronics Engineering (2019)
The aim of this thesis is to design a control moment gyroscope (CMG) with outer rotor BLDC motor for medium size satellites. CMG is a device that provides high output torque to the satellite in order to maneuvering satellites rapidly. CMG is the most efficient actuator in terms of output torque capacity when it is compared with other type actuators such as the reaction wheel. The first step of the designing CMG is to determine CMG design specifications. The mass and volume specifications of the designed CMG...
Choice of Pole Number of Two-Rotor Axial-Flux PM Motor for Control Moment Gyroscope
Özlü Ertan, Hatice Gülçin (2011-09-10)
Modern low earth orbit satellites use control moment gyroscopes (CMG) for maneuvering. GMC's generally use a brushless DC motor to run an inertial wheel at about 10000 rpm. In this paper axial-flux BLDC motor is considered for this task with a view to design a low volume, low weight CMC. Various axial-flux (AF) motor topologies are possible. However, two-rotor AF topology is found to be more advantageous. The specifications of an existing CMG design, based on a commercial BLDC motor are taken as reference. ...

Uğur, Mesut; Keysan, Ozan (2018-10-25)
In this study, design procedure of an Integrated Modular Motor Drive (IMMD) is presented focusing on high power density. The design is based on a permanent magnet synchronous motor (PMSM) and GaN FETs. Fractional slot concentrated windings are used on the stator. Slot/pole combination and winding configuration is selected based on having low cogging torque and high winding factor. An extended motor drive inverter topology is proposed where 2-level voltage source inverters are connected both in series and pa...
Comparison of axial flux and radial flux brushless dc motor topologies for control moment gyroscope wheel applications
Yılmaz, Kurtuluş; Saranlı, Afşar; Department of Electrical and Electronics Engineering (2009)
In this thesis axial flux and radial flux brushless dc motors will be studied as a drive motor for the control of moment gyroscope wheel. Design equations for axial flux and radial flux brushless dc motor topologies will be reviewed. Based on these equations radial and axial flux motors with different number of poles will be designed that meet control moment gyroscope wheel application requirements. The results will be evaluated in terms of efficiency, torque/mass and torque/volume, and suitability for the ...
