    Hi everyone,
    Our team in going to build a formula tech based vehicle. We have got the Suzuki GSX R 600 cc engine. The main requirement for the gear shift is a stepper motor, that can be controlled from driver's seat, i.e. by paddle shift. Now, the main thing is that the gears are not uniform.(first down, remaining up). Can anyone please tell me what to do for getting such stepper motor ??

    Regards,

    Yash.

    I think I'd go with a couple of solenoids instead of steppers. Much less expensive, easy to drive.

    I agree. I built a solenoid controlled shifter for a ten speed bicycle.

    The stepper linear actuator isn't the most reliable for the job.

    For the solenoids, you need only 2. One for up and one for down. That will allow for fast shifting on the fly. If you wanted to downshift two gears with the stepper, It would be a much more involved ordeal for the accuracy. But for the solenoid, it would be a switch connected directly to the solenoid and power.
