Could be a discharge resistor for the capacitor.
Nearly there the start winding needs a change to reverse.As a sufficient quantity of cold drink has now been consumed to make me bold, I'm going to hazard a guess :
This is a single phase induction motor with 2 windings, one start one run. The capacitor is used to create the starting field to make the rotor spin. Changing which coil has the cap connected reverses the spin. A low value R (as this seeems to be ?) can be misused in place of the C to create a lopsided field and get the rotor to start. This is just a thought and could be all rubbish
To what end. As I surmise to reduce the torque?I don't think it's a cap bleed resistor, it's the wrong type and value. It's a high power resistor that's designed to dissipate heat so it shouldn't even really be in that connection box. I'd guess it comes from either the top terminal or the third one down as you look at the photo depending on which direction you want the motor to run. I'd emphasise this is a guess so don't blame me if there's smoke....
