    I have built the circuit shown in the attached image. It is a switching circuit for a switched reluctance motor. I need to add some sort of transducer to improve the circuit and then explain how to integrate it into the circuit. I'm just looking for suggestions as to what transducer I can pick for this kind of motor.

    I picked a tachometer to measure the speed of the motor, but does anyone have any other suggestions as to what I can use?

    Is this for RPM resistration? Either slot Opto or small proximity such as Honeywell SS400 series.

    I don't actually have to build it into the circuit, I just have to explain how I would.

    How would I go about integrating a slotted opto into the circuit?

    A slot opto also requires the addition of a 'shutter' type wheel on the motor shaft or revolving point, the slots of the wheel is tailored to the resolution needed.
    If rpm control is to be implemented using a transducer of any kind requires a comparison between the rate commanded and the feedback, with correction accordingly.
