If there is a brake there will be an additional 2 wires. You can easily check them with a multimeter. The thermal overload ones will have little or no resistance, the tacho will have a static resistance of around 60 ohms and will generate a voltage when the shaft is turned. Also if there is a brake there should be some indication on the name plate of the motor. Dave
