Abstract

Penelitian ini memiliki tujuan untuk mengetahui suatu validitas butir butir skala regulasi diri yang dikemukakan oleh Zimmerman. Terdapat tiga aspek dalam regulasi diri menurut Zimmerman yaitu metakognitif, motivasi, perilaku. Sampel penelitian ini berjumlah 34 responden mahasiswa UIN Sunan Ampel Surabaya untuk pengambilan informasi menggunakan teknik penyebaran kuisioner melalui aplikasi whatsapp dan pengujian dari hasil responden menggunakan aplikasi SPSS. Dari hasil yang didapatkan terdapat 25 item yang valid dan nilai 0,950 dalam uji reliabilitas.

Abstract

Permanent magnet synchronous generators (PMSG) converts mechanical energy into electrical energy through electromagnetic induction, with the excitation field generated by permanent magnets instead of coils. This paper investigates the effects of varying magnet thickness and width on the back electromotive force (back EMF) of an 18-slot 16-pole PMSG using finite element method (FEM) simulations. The aim is to understand how these geometric parameters influence the back EMF values, which are crucial for generator design and performance evaluation. The FEM modelling results show that a 5 mm magnet thickness yields the highest back EMF value of 130.47 V, while a 15 mm magnet width produces a back EMF of 100.65 V. Additionally, the back EMF constant (KE) is maximized at 0.79 V·s/rad for a 5 mm magnet thickness and 0.55 V·s/rad for a 15 mm magnet width. These findings provide insights into optimising magnet dimensions for improving the efficiency and output characteristics of PMSGs in various applications.
