RANCANG BANGUN MOTOR STEPPER VARIABLE RELUCTANCE
(2014-05-22) Anto, Budhi; Wahono, Ambrosius
This paper describes an attempt to design and make variable reluctance stepper motor which is fed from 12 volt dc supply. Stator part of the stepper motor has 6 salient poles and its rotor has 4 teeth. Stator windings are wound around salient poles, while rotor part has no winding. Modeling and simulation of rotor motion of the stepper motor has been conducted during design phase. Simulation results show the rotor part rotates in 30 degrees steps. The design is implemented by using distribution transformer laminated iron sheets which are scissored in such a way to produce stator and rotor laminated sheets. The sheets are joined together to form stator core and rotor core. Stator part, rotor part and other machine components are assembled to form complete variable reluctance stepper motor. A laboratory test set up for the stepper motor shows that its step angle is 30 degrees as same as predicted.
