2.12 Overload Protection

2 2
Take note of the relevant circuit diagram for motors with
thermally activated winding protection (see 2.10 Cage
Clamp Connection Diagram).
Automatic restarting after the winding has cooled must be
avoided in most applications.
The output of the motors is normally adequately rated.
The rated current does not represent a measure of gear
unit utilization in these cases and cannot be used as
overload protection for the gear unit. In some cases, the
way in which the driven machine is loaded can exclude
any overloading as a matter of course. In other cases it is
prudent to protect the gear unit by mechanical means (e.g.
slip clutch, sliding hub etc.). This depends on the
maximum permissible limit torque M in continuous
2
running duty specified on the nameplate.
