Frequency
converters.
Variable-frequency drives sized for Webac unbalance motors. Control speed, torque and direction. Tune amplitude to the bulk material without changing hardware.
Between the mains
and the motor.
The frequency converter sits on the DIN rail in your control cabinet. One cable in from the supply, one cable out to the vibration motor, signal lines to the PLC.
More than
a speed knob.
Speed control
Run your unbalance motor below synchronous speed to fine-tune amplitude and throughput for a specific bulk material without swapping motors.
Soft start
Controlled ramp-up avoids mechanical shock through bearings and springs, extending motor life and reducing peak current draw at switch-on.
Direction
Reverse direction on a two-motor screen or conveyor to clear a blockage or flush a residue without disassembly.
Macros
Built-in vibration-specific parameter sets for screening, compaction, conveying and silo discharge. No cold-start tuning required.
Sized for
Webac motors.
