4. Servomotor
General SIEMENS 1FK7 servomotors are provided to connect with SIMODRIVE
base line A.
1FK7 AC servomotors are extremely compacted permanent-magnetic
synchronous motors. Together with the SIMODRIVE base line A, the 1FK7
motors are powerful system with high functionality. The built-in resolver
system is used to control the speed and position.
The motors are designed for operation without external cooling, and the
heat is dissipated through the motor surface. The 1FK7 motors have a high
overload capability.
Technical data Refer to Table 4-1 for the technical parameters of 1FK7 motor.
