<![CDATA[Electrical machinery plays a very important in industry and in everyday life hari. Exsitasi or starting a means used by man to ignite and drive the electrical machinery. The way or starting exsitasi electrical machines taken by man to get a good efficiency power efficiency and torque efficiency. Thus it takes a piece of equipment that is capable of performing exsitasi electrical machines with a small power with big torque. Inverter or more commonly known as VSD (Variable Speed Drive) is one option which is used in making exsitasi or starting the electric machines. The inverter is able to perform exsitasi electric machines both single phase and 3 phase with prefix absorbs very little power and have very besar.Contoller torque inverter done so fine that almost did not happen rebound flow and speed that can cause damage to the machines The electricity nor the couple or connecting circuits. In the world of industrial inverter controlled semi-automated and automated by the semi-automatic circuit. Automatic performed by a series of contactors and relays, while the control is automatically done by the PLC (Programmable Logic Control). Arduino can be used as a substitute for controlling performed by contactors, relays and PLC. Arduino able to control the start-stop, round forward and reverse rotation and control the motor rotation speed can be displayed in the display LCD (Liquid Cristal Display)]]>
