perencnaan sabuk Mate 4-inch-diameter sheave with 6-inch-diameter sheave. Their centerlines can range from 18 to 20 inches apart. Select length of belt and determineactual centerline distance. If small sheave rotates 1800 rpm, determine ratio and surface speed. Find the angle of contact for the small sheave. Answer : D1 = 4 inchi D2 = 6 inchi C    =  18 – 20 inchi n    = 1800 rpm

MOTOR LISTRIK MOTOR FASA BELAH Konstruksi motor induksi satu fasa sama dengan motor induksi 3 fasa, bedanya kumparan stator hanya ada 1 fasa. Sumber bolak balik dari jala – jala listrik yang mengalir melalui kumparan stator pada motor induksi satu fasa akan menghasilkan fluks bolak balik di sekitar kumparan stator tersebut. Motor split phase menggunakan sumber listrik arus tukar. Ada 3 bagian utama pada motor yaitu : 1. Bagian yang berputar disebut rotor 2. bagian tetap disebut stator 3. saklar sentrifugal Bentuk kumparan rotor menggunakan type gulungan kurungan (squirrel cage winding) yang terdiri dari sejumlah kumparan kawat tembaga yang dimasukkan dalam alur-alur rotor dan ujung-ujung dari masing-masing kawat tembaga dilas pada komutator. Kumparan stator terdiri dari kumparan tembaga atau kawat tembaga atau kawat tembaga yang dimasukkan dalam alur-alur stator yang dikenal dengan kumparan utama (main winding) dan kumparan kawat tembaga lain yang dise...
