Abstract
This paper presents design and analysis of a three phase induction motor drive using IGBT‟s at the inverter power stage with volts hertz control (V/F) in closed loop using a microcontroller. A 1HP, 3-phase, 415V, 50Hz induction motor is used as load for the inverter. Oscilloscope is used to record and analyze the various waveforms. The experimental results for V/F control of 3-Phase induction motor using GSM clearly shows constant volts per hertz and stable inverter line to line output voltage.
Introduction
In the present time, in the most of the applications, AC machines are preferable over DC machines due to their simple and most robust construction without any mechanical commutators. Induction motors are the most widely used motors for appliances like industrial control, and automation; hence, they are often called the workhorse of the motion industry[6]. As far as the machine efficiency, robustness, reliability, durability, power factor, ripples, stable output voltage and torque are concerned, three- phase induction motor stands at the a top
of the order. Motor control is a significant, but often ignored portion of embedded applications. Motor control applications span everything from residential washing machines, fans to hand-held power tools, and automotive window lift, traction control systems and various industrial drives. All most in all the applications there is a drastic move away from analog motor control to precision digital control of motors using different processors. Digital control of induction motors results in much more efficient operation of the motor, resulting in longer life, lower power dissipation. Although various induction motor control techniques are in practice today, the most popular control technique is by generating variable frequency supply, which has constant voltage to ratio frequency ratio. This technique is popularly known as V/F control [3]. This work describes the design of a 3- phase AC induction motor drive with volt per hertz control in closed loop (V/F) using High-Performance
Controllers. tem as all its operations are controlled by intelligent software inside the microcontroller. The aim of this project is to control i.e. to ON/OFF and speed control of different motors, the electrical or electronic appliances connected to this system from anywhere in the world. For this purpose user can use any type of Mobile. This way it overcomes the limited range of infrared and radio remote controls. Using the convenience of SMS, this project lets you remotely control equipment by sending into the controller and easily remembered later. It can control up to eight external devices Short Message Service (SMS) is defined as a text-based service. control up to eight external devices Short Message Service (SMS) is defined as a text-based service. That enables up to 160 characters to be sent from one mobile phone to another. In a similar vein to email, messages are stored and forwarded at an SMS centre, allowing messages to be retrieved later if you are not immediately
available to receive them. Unlike voice calls, SMS messages travel over the mobile network„s low-speed control channel.
