660V AC Medium Voltage VFD Frequency Converter Drives for Mixers

Mixers are used in a wide range of industries to combine different materials together to form one final product from the mixing process. The mixed materials can be mixed from low to high viscosity, high to low viscosity, or mixed at a constant viscosity. Mixtures may require the mixer to operate at various speeds throughout the mixing process. The properties of the mixed material are a primary consideration when defining mixing applications.

Application Challenges

· High starting torque
High viscosity materials will require a high amount of starting torque to get the mixer blades rotating.

· Mixture status
Determine the viscosity of the mixture while the mixer is operating.

· Trip-less operation
The drive must be capable of continuous operation or automatic restart after a momentary power loss or fault (< 5 ms).

· Multiple mixing speeds
Capable of changing mixing speeds throughout the mixing process for different mixtures.

· Equipment protection
Capable of detecting seizing or jamming of the mixing equipment (shaft, mixer blades, mixer paddles, etc.) and respond to avoid damage to the equipment.

Features of G7 matching mixer application

Features	Benefits
Open Loop Vector and V/Hz Control with Torque Compensation	Provides excellent breakaway torque for thick materials and constant torque to maintain mixing speeds under heavy loads.
Overtorque Detection	Provides early warning of damaging torque levels as a result of seizing mixer blades.
Torque Reference programmable to an analog output	The applied mixing torque is fine tuned or adjustable for different material.
Preset frequency reference	Preset mixing patterns can be established for different materials.
Auto-Restart after momentary power loss	Mixing can quickly restart after fault or momentary power loss. This keeps perishable foods from spoiling in process.
Power loss Ride-Through	The mixing process in not interrupted during brief power loss (< 5 ms).
