An
electromagnetic torque limiter was designed for one
of our customers to combine the electromagnetic clutch
with an overload clutch and give both the functions
through one compact unit.
During
the operation the clutch transmits a pre-set limited
torque which can be continuously adjusted by the adjustment
of the coil current. The clutch disengages if this torque
is exceeded and thus the input and output sides are
disconnected. Simultaneously a limit switch is actuated
which switches of the magnetic coil of the clutch.
In a
multi-purpose Candy/Tablet Packaging Machine, this innovative
produce is used for overload control of the feeding
table in case the candies/tablets which are fed get
accidentally stuck up. By setting the limiting torque
electronically based on the candy/ tablet size/weight
specifications, this clutch can be remotely manipulated.
In case the product gets stuck during the feed, the
torque is exceeded and the drive disconnected, bringing
the machine to a stop followed by removing or taking
action on the cause. By controlling the current, the
limiting torque can be remotely set. The limiting torque
for the overload at the clutch can be continuously set
via manipulation of the coil current or the coil voltage
which is adjustable during operation. |
