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

DC MOTOR CONTROL USING CHOPPER


ABSTRACT

The speed of separately excited DC motor can be controlled from below and up to rated speed using chopper as a converter. The chopper firing circuit receives signal from controller and then chopper gives variable voltage to the armature of the motor for achieving desired speed. There are two control loops, one for controlling current and another for speed. The controller used is Proportional-Integral type which removes the delay and provides fast control. Modeling of ....etc

The basic principle of the DC motor is a device which converts DC energy into mechanical energy. When the current carrying armature is connected to the supply end though commentator segment, brushes are placed within the North South Poles of permanent or electromagnets. By using these electromagnets operating principle is depends on the Fleming s left hand rule to determine the direction of the force acting on the armature conductors of the DC motor.
