control dc motor

hi can help my :
I NEED design control speed dc motor use IGBT
motor 220V,15A,3hp

Re: control dc motor

The usual method is to pulse width modulate the voltage to the motor.

Re: control dc motor

ST/Shingdengen/allego have such control chip,you can use such schip to control IGBT ,then to control DC motor.
The basic theory of small or Large DC motor is same.

is there any dedicated processor which can perform better for a brushless motor controller

control dc motor

For simple application, you can use the following ICs:

MC33033
BRUSHLESS DC MOTOR CONTROLLER
Motorola

MC33035
BRUSHLESS DC MOTOR CONTROLLER
Motorola

MC33039
CLOSED LOOP BRUSHLESS MOTOR ADAPTER
Motorola


Texas Instrument offers TMS2000 series DSP controllers that are optimized for motion control application. For higher end application of BLDC motor, you can consider to use this controller. There are many design examples/codes available at TI website.

u can use pulse width modulation using 555 and drive the motor using a relay

control dc motor

some microcontrollers can drive PWM signals if i'm not mistaken.

It's bad idea. Coz when you are switching motor the Relay will BURN !!!. Maybe you should read some Laws - The Ohm first
