Overview
SIMOTICS S-1FK7 feed motors in SH 63/SH 48 with DQI encoder
SIMOTICS S-1FK7 motors are compact permanent-magnet
synchronous motors. 1FK7 motors can be combined with the
SINAMICS S120 drive system to create a powerful system with
high functionality. The motors are designed for operation without
external cooling and the heat is dissipated through the motor
surface. 1FK7 motors have a high overload capability.
The SIMOTICS S-1FK7 feed motors are perfectly adapted to the
SINAMICS S120 Combi drive system.

Benefits
7
Maximum machine dynamics thanks to optimum relation
between torque and motor moment of inertia
7
Very high torque even at high speeds as a result of the special
field weakening concept
7
Excellent machine precision thanks to high resolution of motor
encoder and high-precision shaft and flange mounting
7
Very fast acceleration thanks to triple electrical overload
capability
7
High degree of ruggedness because encoder is mechanically
decoupled from the motor shaft
7
Maintenance-free absolute encoders without battery
7
High energy efficiency
SIMOTICS S-1FK7 Compact motors
7
Space-saving installation due to extremely high power density
7
For universal applications
7
Wide range of motors
SIMOTICS S-1FK7 High Inertia motors
7
Robust closed-loop control properties for high or variable load
moment of inertia
7
Minimal optimization and commissioning overhead for the
compensation of disturbances
