help to run dc brushless motor

[infidelboy]

i have bought a brushless motor from robokit and tried to run it with at89s52.. but i am not able to run it.

here is image of motor i bought


at the input power pin, i have applied a 12 V dc.
at the other three pins i have applied the control pulse, but it is not working.

here is the programing code for the control pins i used

#include <regx51.h>
sbit i1=P2^0; //for control pin 1
sbit i2=P2^1; //for control pin 2
sbit i3=P2^2; //for control pin 3
void MSDelay(unsigned int);
void main()
{ P2=0x00;
while(1)
{
i1=0x01;
MSDelay(40);
i2=0x01;
MSDelay(40);
i3=0x01;
MSDelay(40);
i1=0x00;
MSDelay(40);
i2=0x00;
MSDelay(40);
i3=0x00;
MSDelay(40);

}
}

void MSDelay(unsigned int a)
{
unsigned int i,j;
for (i=0;i<a;i++)
for (j=0;j<1275;j++);
}


resulting in output as attached file..


whats wrong here...
