Servomotors 1FK7
1FK7 motors are permanent magnet excited synchronous motors which are available in the versions Compact, High Dynamic and High Inertia.
The self-cooled motors are characterized by superior overload capability, ruggedness and compactness.
The connection via rotatable connectors and preassembled cables ensures a flexible, fast and safe connection to the converter.
1FK7 Compact (CT)
- The universal motor for a wide range of applications.
- Space-saving installation through very high power density.
- Large range of motors in the shaft heights 20 to 100.
- Preferred types with short delivery times are available.
1FK7 High Dynamic (HD)
- The sprinter in the ramp-up time
- Very high acceleration capability due to low rotor moment of inertia.
- For highly dynamic applications with low load moment of inertia.
1FK7 High Inertia (HI)
- Docile control behavior with superior load inertia due to the high intrinsic moment of inertia.
- Reduced expenditure for controller optimization.
- Particularly suited for machine tools for feed axis applications requiring superior resp. alternating load inertia..
