Abstract

Electric vehicle engines are the same as vehicles with combustion motors, namely they are an assembly of several mechanisms consisting of three main parts, namely the drive, the power transmission system and the driven part. The electric car used for this research is a conversion of a petrol car, where the drive uses a 3 KW BLDC electric motor. The BLDC motor shaft power is transmitted to the axle pinion shaft using a sprocket gear transmission. So an analysis of the sprocket gear design, both ratio, size (type), strength and age of the sprocket gear to be used needs to be carried out. The initial step is to calculate the design power by looking at the correction factors in the table for the type of electric motor drive, then determining the chain number on the graph by first calculating the torque moment. The linear speed of the chain that occurs is influenced by the size of the gears and the input rotation of the electric motor, the greater the speed, the smaller the torque, so the gear ratio needs to be considered in determining the maximum linear speed. After knowing the chain plan number, it can be tested by calculating whether the chain number technically meets good security or not. In this research, the sprocket chain design, namely chain roller number 40 with a maximum load of 33.74 kg, is good, namely greater than sf = 6.

Abstract

Current refigeration technology has an important influence in improving the quality of food products. The purpose of this study is to find out how much the difference in performance generated from the expansion device in the form of two capillary pipes of different diameters and know the power consumption of electricity used, so that it knows the electric power per day. The method used in this study is to test the ice cream maker refrigeration system, by testing its performance by measuring the temperature and pressure in each main component when the system is steady. The results of the actual COP value of the average capillary pipe diameter of 0.028 inches are 2.16 while the actual COP value of the average capillary pipe diameter of 0.031 inches is 2.74. And the actual COP value of a 0.028 inch diameter capillary tube has a greater value of 2.16 while a capillary pipe with a diameter of 0.031 inches has a smaller value of 1.88. Whereas the biggest value of refractive efficiency at the average value is a capillary pipe with a diameter of 0.028 inches of 63.58%. While for capillary pipes with a diameter of 0.031 inches smaller the value of refraction efficiency averaged 59.49% and the cabin temperature in capillary pipes with a diameter of 0.028 inches, the average value was -9.82 0C. While for capillary pipes with a diameter of 0.031 inches smaller it has a cooler average value of -9.09 0C.

Abstract

The prototype tool of the hydroelectric power plant is an engineering tool as a demonstration of a power plant that is moved by water. So the tool will be redesigned by researchers as a comparison of courses in mechanical engineering study programs, especially engineering thermodynamics courses. In the design of the tool will be designed using the solid work computer program. Then in the selection of design components that are used are easily obtained or within reach of purchasing the tool, namely the frame holder for the power plant using holo steel, a water pump using a 260 bit jet pump that uses 200 watts of electric power, electricity supply using an alternator that has 200 watts of electric power. The water-driven turbine is the process made using Pvc pipe which has a tilt angle on the blade of 30 o. turbine cover using acrylic material with a thick size of 10 mm, water reservoir using steel plate size 4 mm and lamp load that will be tested 100 watt capacity. At the capacity of this tool requires a cost of approximately Rp. 5,811,500,
