ABSTRACTThis undergraduate thesis discusses the design, optimation, and simulation of a squirrel cage induction motor for electric car application, by using Soft Magnetic Composite SMC material as the motor core material. This research uses the experimentation and simulation method, where design and optimation is conducted based on the existing instructions and formulas to be imported to the designed motor that will be simulated. Simulation results show that the motor rsquo s Final Design can be used for electric car application, although it has a few drawbacks in its starting torque and efficiency aspect."

"Dalam pengoperasian motor induksi 3 fasa tipe squirrel cage dengan kapasitas besar perlu diketahui parameter utama agar dapat memprediksi kondisi pengoperasian itu sendiri. Gejala umum dalam kondisi pengoperasian adalah suplai tegangan tak seimbang, arus lebih yang menyebabkan panas lebih. Suplai tegangan tak seimbang akan menyebabkan penurunan kinerja motor induksi. Parameter yang dilihat adalah efisiensi dan derating factor. Kemudian dalam skripsi melihat perbandingan standar antara NEMA, IEEE dan IEC dalam menganalisa kinerja motor induksi. Secara umum metode ini berupa metode non destruktif dengan memakai simulink MATLAB, karena tidak langsung menggunakan peralatan. Hasil simulasi ini memudahkan untuk proses pengoperasian seperti misalnya pemeliharaan, kondisi tegangan lebih, proses starting dan stopping motor induksi.

In the operation of three phases induction motor whose type is squirrel cage with large capacity, main parameters are needed to be known in order to predict the operating conditions. Common indications in operating conditions such us; unbalance supply voltage, over current, which cause overheating. Unbalance voltage supply will cause derating performance of induction motor. The parameters which will be analyzed are efficiency and derating factor. Then, in this final project show the comparation of NEMA, IEEE and IEC to analyze performance of induction motor. Generally, this method is a non destructive method using MATLAB Simulink, since it does not use the equipment directly. The result of simulation abridges to process such as maintenance operation, overvoltage conditions, the process of starting and stopping the induction motor."

"Most heavy duty mining electrical drives employ squirrel cage induction motors (SCIMs) which are subjected to various undesirable stresses. Therefore, condition monitoring of the SCIMs is indispensable for achieving production goals with minimum downtime in a fault-free working environment. Because bearing damage is the most frequently occurring fault in SCIMs, an effective fault detection scheme will aid in achieving production targets in an industrial mining scenario. In this regard, the present work intends to propose an effective fault monitoring algorithm, which is immune to supply frequency regulation, for the detection of ball bearing damage in an SCIM. Discrete Wavelet Transform (DWT) is used for the design of the fault detection scheme. Validation of the proposed scheme is done in a LabVIEW based laboratory interface. The complete analysis is carried out in MATLAB/ Simulink using a 5.5 kW, 3-phase, 415 V, 50 Hz SCIM."
