The electric cylinder comprises a CASM linear unit supplied by EWELLIX and a SIMOTICS S-1FK7 motor. The CASM linear unit converts the rotary motion of the SIMOTICS S-1FK7 motor into a highly dynamic linear movement and is a perfect substitute for pneumatic or hydraulic cylinders in many applications. By contrast with pneumatic and hydraulic cylinders, electric cylinders allow the driven machine to approach any position with extreme precision solely on the basis of setpoints transferred to an inverter from the SINAMICS S120 range.
Benefits:
- Modular system with wide variety of options.
- Substitute for hydraulic and pneumatic cylinders in most applications.
- No compressed air/hydraulic fluid required – helps to cut costs (no need to supply compressed air or hydraulic fluid), reduces noise emissions significantly and lowers energy consumption in operation.
- Highly dynamic, precise positioning with high repeat accuracy.
- Mechanical conversion is simple because electric cylinders are essentially the same size as pneumatic cylinders. Furthermore, the relevant pneumatic cylinder accessories can also be used for electric cylinders.
- The SIMOTICS S-1FK7 motors are attached to the linear unit by means of adapters supplied by EWELLIX, making it very easy for the customer to install the motor.
Application:
The electric cylinders (CASM linear unit supplied by EWELLIX in conjunction with SIMOTICS S-1FK7 motors and SINAMICS S120 converters) can be used for any application which requires a linear motion and/or a defined force. Their areas of application are the same as those for pneumatic and hydraulic cylinders.
The electric cylinders are used, for example, in production machines such as:
- Machines used in the wood, glass, and ceramics industries
- Metalworking and coating machines
- Printing machines
- Plastics processing machines
- Packaging machines
Function examples:
- Positioning of cutters
- Edge guidance/edge cutting
- Retainers
- Buffers/sorters/slide gates
- Nozzle holders
Notes:
- Technical advice must be sought for applications involving continuous short-stroke movements (less than three times screw pitch).
- The electric cylinder must be assembled (depending on the stroke length) in such a way as to minimize lateral forces.
- The electric cylinder is not self-locking – it might be necessary to provide a motor holding brake.
