Use kenoweb core plugin, it's free, and works OK, tested with SE 4.1.7 and 4.1.8p1
In case of use version >= SE 4.1.8 just drag&drop widget rate-this into place where you want to be ratting showed

In case that you want to incorporate widget rate in older version than SE 4.1.8 (<= SE 4.1.7) use this code:

PHP:

<?php echo $this->content()->renderWidget('Kowcore.rate-this') ?>

This line of code you can put any where you want to be showed
