universal motor speed control using avr microcontroller

Controlling direction and speed of DC motor is very essential in many applications like

Robotic application to change direction and speed of moving robot

Industrial application to change direction and speed of rotating machinery

Domestic application to vary speed of battery (DC) operated portable fan

Defence application to rotate radar, automatic gun, tank gun in either direction

Communication application rotate dish antenna upward downward or clockwise - anticlockwis ....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

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
