Abstract

Shaded pole induction motors are most widely used for everyday use, for low-power equipment, such as: fan or blower drive. But in use, the motor quickly decreases its speed and the sound gets louder. This is due to the high value of the losses on the motor, which results in a low value of efficiency, 59.1%. High losses cause the motor to heat up, so that the speed decreases and the sound becomes even more noisy. In the shaded pole induction motor, the iron core is very dominant, it can reach 60% of the total motor material. This will make the magnetic field path long, which can result in lower motor efficiency. To resolve this low efficiency, it is better if the motor coil wire dimensions are enlarged to reduce the motor impedance

Abstrak--Motor induksi jenis kutub terbelah (shaded pole) paling banyak digunakan untuk penggunaan sehari-hari, yaitu untuk kebutuhan dengan daya rendah, seperti : penggerak kipas angin atau blower. Tetapi dalam penggunannya, motor tersebut cepat mengalami penurunan kecepatan dan suaranya semakin keras. Hal ini disebabkan karena tingginya nilai rugi-rugi pada motor tersebut, yang berakibat rendahnya niali efisiennya, yaitu 59,1%. Rugi-rugi yang tinggi menyebabkan motor menjadi panas, sehingga kecepatannya menurun dan suaranya semakin bising. Pada motor induksi jenis shaded pole, inti besinya sangat dominant, dapat mencapai 60% dari total material motor. Hal ini akan membuat jalur lintasan medan magnetnya panjang, yang dapat mengakibatkan rendahnya efisiensi motor. Untuk mengatasi efisiensi yang rendah tersebut, maka sebaiknya dimensi kawat kumparan motor diperbesar untuk menurunkan impedansi motor
