TERMINAL BOX
When the motor winding is supplied with the polarity indicated on the terminal box (B+, E-), the
rotor turns clockwise (CWR, clockwise rotation), as shown in the diagram. And, for this turning
direction, the tacho generates a voltage at its terminals (Tacho) also with the polarity indicated on
the box (+, -).
The electromechanical brake releases the motor shaft when applied 24 Vdc.
When stationary, it holds the motor shaft.
The thermal switch watches the armature temperature.
