Speed control of three-phase asynchronous motor USING DSPIC30F4011
introduction
Induction motors are widely used in high-performance drive systems, due to ITS Advantages as highly effective, very simple in construction, good power factor and does not require any engine start. Variable speed Operation CAN BE achieved by an asynchronous engine. So, now a days in many applications, such as washing machine and all the asynchronous Motors only desired.
Speed control method
Various speed control of AC asynchronous motor variable methods such as fre ....etc

The DC motors are applicable for effective speed control and high starting torque applications like traction, lift, etc. The Pulse Width Modulation twchnique of speed control can be used to obtain a a smooth speed variation without actually taxing in on the high starting torque of the motor. PWM technique also eliminate harmonics. Pulse-width Modulation is achieved with the help of a square wave whose duty cycle is varied to get a varying voltage output. As the average voltage output depends on the duty cycle of the square waveform, the actual ....etc

pwm based on dc motor control using at89s52 microcontroller

A pulse width modulator (PWM) is a device that may be used as an efficient DC motor speed controller or light dimmer. This project is a versatile device that can control DC devices which draw up to a few amps of current. The circuit may be used in either 12 or 24 Volt systems with only a few minor wiring changes. This device has been used to control the speed of the DC motor and to control brightness of an automotive tail lamp. A PWM circuit works by making a square wave with a variab ....etc

The liquid crystal display (LCD) is very commonly used electronic display module and have a wide range of applications such as calculators, laptops, mobile phones etc. 16 2 LCD character display is a very basic module that is used Commonly in electronic devices and projects. It can display 2 lines of 16 characters. Each character is displayed using 5 7 or 5 10 pixels matrix.Interfacing 16 2 LCD with 8051 using Keil C is a bit complex because there are no powerful libraries in Keil C. To solve this problem we have developed an LCD library Wh ....etc
