 SCL

Operation of synchronous motors without encoder feedback The optimization of effi ciency, available space and increasing dynamic forces the use of synchronous motors, which can be operated by F5-E (SCL) and F5-P (safety version) now without rotor position feedback in all applications without positioning tasks. The calculated control method of the software has no e ect through external disturbances and leads to high smoothness. Mechanically stressed motors, high frequency special machines or high-volume torque motors are operated more functional and safe with elimination of the encoder system.

Properties

 

• standstill position detection (calibration without rotation)
• operation with output f lters
• low installation costs in case of loss of encoder line, encoder and encoder interface
•  high dynamic / non-slip rotation
•  reduced installation space / lower weight
• high effi ciency / high availability
• Potential applications
•  driven tools in working stations
•  synchronous process chain in textile machines
•  hybrid drives
•  diesel electric drives in conveyor systems, container or heavy duty vehicles
•  electric drives in boats, yachts and vehicles
•  synchronous extruder
•  injection moulding technology / blow moulding technology
• high frequency pump drives in compressors, screws, vacuum pumps
