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.
Failure of pacemakers or implant malfunctions due to electromagnetic fields
Electromagnetic fields (EMF) are generated by the operation of electrical power equipment,
such as converters or motors. People with pacemakers or implants in the immediate vicinity
of this equipment are at particular risk.
Deviating from the notes in Section "General safety instructions (Page 11), applies to the
1FK2 motors:
● If you are affected, stay at a minimum distance of 30 cm from the motors.

Dynamic versions

● 1FK21 "High Dynamic" with low moment of inertia for a maximum acceleration capability
in applications with 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

Power range

0.05 kW ... 0.75 kW for a line supply voltage of 230 V 1 AC

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:
