Extrusion machines are used to create product by forcing raw material, such as plastic, through a die. Extruders are used to create a wide range of products such as tubing, sheet goods, and insulation. Food processing is a popular application for extruders. Extruders employ a main drive motor to supply power to a screw, which provides the force necessary to push the raw material through the die.
- Replace hydraulically operated or DC powered drives
- Precise speed control while material is being extruded
- Develop high torque at very low speeds
Drives Products | Servo and Motion Products
|Dwell and Timer Functions||Allows the drive to operate automatically without setting up an external run sequence.|
|Variable acceleration and deceleration times||The drive allows the user to switch easily to different acceleration and deceleration preset times when working with softer mixtures or harder mixtures.|
|Multi-Step Frequency Reference||A 17-step Preset Speed Reference is available when working with difficult mixtures of various materials.|
|Frequency Upper/Lower Limit||The drive is constrained to run within the Upper and Lower Frequency Limits even if a value outside that range is entered accidentally.|
|Adjustable Speed Control|
|A push button UP-DOWN switch can be used to make incremental speed adjustments instead of an analog speed pot input. Use Trim Control function to make fine adjustments to the extruder speed.|
|Overtorque and Undertorque Detection||The drive is capable of detecting the consistency of mixtures and protect the load by using Overtorque and Undertorque Detection.|
Stall Prevention During Accel/Decel,
Stall Prevention During Run
|The drive is capable of both protecting the load and detecting any foreign materials introduced to the mixture by setting optimal values for Torque Limits, Stall Prevention During Accel/Decel, and Stall Prevention During Run.|

The extruder main drive motor supplies power to the extruder screw providing the force necessary to push the raw material through the die.
Yaskawa motion control products and AC drives are digitally controlled and designed to develop high torque at low speeds. Since the extruders are often started with the barrels full of dense material; such as plastic, they need to quickly develop a large amount of torque to overcome the inertia.
The precise control of speed offered by Yaskawa products allow the operator of the extrusion machine to repeatedly produce products that are within design tolerances. Some features are designed to protect the equipment. Torque limiting controls protect the motor from overload if the mixture’s consistency changes.
Yaskawa drives include built-in application expertise. If the operator accidentally enters a value outside of the upper or lower speed limits, the Yaskawa drive continues to keep the speed within limits. Acceleration and deceleration controls allow the operator to easily change from hard to soft mixtures.
Yaskawa motion control solutions include application programming flexibility and integration to a wide variety of third-party devices. Recipe tables can easily be created offering great flexibility for various product runs. Acceleration and deceleration controls allow the operator to easily change from hard to soft mixtures without ever worrying about specific values.
