    Lehung,
    Did you try to build a 5pase stepping motor with SI-7510 + SLA5073 + SLA5074? I'am testing with those IC and it work well. It seem to easy to build a driver.

    Thanks for your reply,
    As your suggestion, I think at any time there are three coils of the motor disable, so may be it will be reduce torque...I will try and see how the result. Thanks.
