Motor

The SIMOTICS S-1FK2, called "1FK2" in the following, is a permanent-magnet compact
synchronous motor with an integrated encoder and a high degree of protection.
The 1FK2 meets the requirements of standards EN 60034 and EN 60204-1 - and complies with
the Low-Voltage Directive 2014/35/EU.
Malfunction of active implants due to magnetic and electrical fields
Electric motors pose a danger to people with active medical implants, e.g. heart pacemakers,
who come close to these motors.
● If you are affected, stay a minimum distance of 300 mm from the motors (tripping threshold
Dynamic versions
● 1FK21 "High Dynamic" with low moment of inertia for a maximum acceleration capability in
applications involving low load moments of inertia
● 1FK22 "Compact" with average moment of inertia and precise positioning and synchronous
operation characteristics for applications with a high and variable load moment of inertia
Torque range
● 0.16 Nm ... 2.4 Nm for a 230 V 1 AC line supply
● 1.3 Nm ... 40 Nm for a 3 AC 400 V line supply
Degree of protection
● IP64
● IP65 with a radial shaft sealing ring to protect against spray water
For additional information on the degree of protection, see Chapter:
Cooling
The 1FK2 is a non-ventilated motor.
The motor thermal losses are dissipated by thermal conduction, thermal radiation and natural
convection.
If the ambient temperature exceeds 40 °C (104 °F) or the installation altitude 1000 meters
above sea level, you must reduce torque and power of the motor (derating).
Information on derating can be found in Chapter:
