speed MOTOR BLDC (brushless)

[Anonymous]

good morning evry one

   

Am working on a project with psoc 4, i want to pilot a motor brushless with a drive carte "BLHD30K", and i want to calculat the speed motor!!

   

this drive carte give a Pulse signals (pulse width: 0.3 ms) of 30 pulses per revolution of the motor output shaft are output in synchronism with the motor drive.
Motor speed can be calculated by measuring the SPEED output frequency.

Motor speed [tr/min] =(SPEED output frequency (hz)*60)/30

SPEED output frequency =1/T
 

   

like that i can also calculat the position of the motor by using an interruption every 30pulse -----> one revolution (tour),

   

but i dont khnow how to calculat that? any idea !!

   

thank you
