Optocoupler to power DC motor

Is it possible to use an optocoupler to power a DC motor?· I've used relays, but would like to switch to optocouplers if I can.

Is there one you would recommend?· My motor draws around 500mA at startup.

Thanks.

    Use an opto-isolator to turn on a power transistor.
