2.3 Technical features and environmental conditions
1FN3 linear motors
34 Configuration Manual, 10/2018, 6SN1197-0AB86-0BP2
Table 2- 1 Standard version of the 1FN3 range of motors: Technical features
Permanently excited synchronous linear motor
Type of construction Individual components
Degree of protection
according to EN 60034-5
• Primary section: IP65
• Mounted motor: The degree of protection depends on the
machine design and must therefore be realized by the machine
manufacturer; minimum requirement: IP23
Cooling method Water cooling
• Maximum pressure in the cooling circuit: 10 bar = 1 MPa
• Wiring: with G1/8 pipe thread (in compliance with
DIN EN ISO 228-1); special connectors are required to connect
hoses/pipes
Thermal motor protection In the primary section:
1x PTC for thermistor triplet with response threshold +120 °C
(according to DIN 44081/44082)
Temperature monitoring In the primary section:
1FN3xxx-xxxxx-xxx1 with 1 x KTY 84
(according to EN 60034-11)
1FN3xxx-xxxxx-xxx3 with 1 x Pt1000
Nameplate for secondary
Enclosed separately
Insulation class of motor
winding according to
Temperature class 155 (F)

Connection, electrical 1FN3050:
Signal and power cables with connectors or open core ends
permanently connected to the motor
1FN3100 ... 1FN3900:
Terminal panel with cover integrated in the motor, with metric cable
glands for signal and power cables. Additional cover with heavy-
gauge threaded joint for combined cables for
1FN3100-xW ... 1FN3900-xW
Encoder system
• Not included in the scope of supply
• Selection based on application-specific and converter-specific
constraints
