Electric motor is an electric machine that has a function as a converter of electrical energy into mechanical energy. Electric motors are widely used as movers because they are better in terms of technical and economical, but have disadvantages such as large initial currents so that they cannot last long, to overcome this can be used Y-utan star starting method both manually and automatically created in a panel box. In the operation and manufacture of a protection system for a 3 phase induction motor, some supporting equipment can be arranged in a panel box so that motor performance can be maximized. The results of this tool design are in the form of a panel box in which there are three types of circuits, namely: 3 phase induction motor operation circuit with the starting Y-∆ automatically, reversing the direction of 3 phase induction motor rotation, and 3 phase induction motor operation in two places. Where the series is equipped with a protection system and can be operated manually and automatically.

Motor execution improvement and fumes discharges decrease are two most significant issues to build up an increasingly productive motor with less natural effect. For diesel motor, cylinder geometry is one of the real parameter that influences the motor performance and emissions. In this present research work, engine performance improvement and exhaust emission characteristics reduction was reducing with the help of some modification in piston geometry by using 3 different types of piston geometries. Horizontal, Toroidal and Re-entered pistons. These can be tested on single cylinder water cooled ci motor. Varying Different type's pistons were analyzed and emissions HC, CO, CO2, O2 and NOx were studied with 5-gas exhaust gas analyzer. The toroidal cylinder gives the best performance and lower emissions at all load conditions

The focus of this paper is the potential electrification of specialized agricultural tractors involved in vineyards and orchards. This category of machinery has not received research attention to date; however, regulations are encouraging lower emissions and higher efficiency, requiring the adoption of new technologies. Traction makes up only a limited part of this application, and the working cycle is not trivial; therefore, the design of the system is not straightforward. This study takes advantage of experimental measurements carried out under real operating conditions on a traditional specialized tractor, which was chosen as performance target. The performance requirements of the hybrid powertrain components are investigated, with particular focus placed on the electric motor. According to the dimension constraints, the design of the electric motor is carried out considering the requirements in terms of its thermal-equivalent torque and overload capability. The results are validated through a detailed thermal simulation under real duty cycles.
