Robots, handling systems and conveyor technology
Feed and auxiliary axes for machine tools

SIMOTICS S-1FK7 - product selection With our SIMOTICS S-1FK7 servomotors, you can choose between three inertial designs depending on the requirements for dynamics, control behavior, accuracy and space.

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

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

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.
