diodes bridge on stepper motor application, why & help

[sp]

dear all,

please help me, i need information regarding the diode bridge used in stepper motor application.

i understand tht it is used to provide protection to the switch or controller... and i also know to protect against voltage spike cause by motor winding during switching..

but does anyone hav a more details explaination on tht, more technically... like showing how current n voltage behavior?

i hav search wth the google... but all the info i get is the same as i know (protect against spike)... any one hav any resources tht explain it more technically (wth diagram)?..

please help me.. thank you...

thanks a lot

warm regards,
sp
