been specially designed to
satisfy the high requirements
placed on variable-speed
drives.
Versions
• Synchronous servomotors
• Asynchronous servomotors
Principal characteristics
• Compact design
• High power density and
overload capability
• High maximum speeds
• Integral encoder system
• High dynamic response due
to low rotor moment of inertia
• Excellent concentricity
properties
• Rugged, almost
maintenance-free design
Synchronous servomotors
The special synchronous
servomotors characteristics
include
• high overload capability,
• high dynamic response and
• high static torque.
1FK6 and 1FK7 servomotors
The 1FK6 servomotors satisfy
the requirements in the lower
power range from 0.5 kW to
5.2 kW. Their optimized design
means they are the most
economical solution for many
applications.
The new 1FK7 servomotors
are based on the experiences
gained with the 1FK6 range,
and are especially characterized
by
• an extremely high dynamic
response
（1FK7 HD, high dynamic）,
• compact design
（1FK7 CT, compact） and
• expanded range of performances
and options.
1FT6 servomotors – high
performance
The 1FT6 servomotors can be
used for extreme requirements
in a power range from
0.2 kW to 45 kW.
These motors are available
with self-cooling in protection
classes IP 64 to IP 68, with
separate cooling, or with water
cooling. The wide range of options
means they are the optimum
solution for many highend
applications.
1FS6 servomotors –
explosion-protected
The 1FS6 servomotors are
designed for use in Zone 1
hazardous areas. These
motors conform to type of protection
EEx de IIC T3.
1PH7, 1PL6, 1PH4 asynchronous
servomotors
The compact asynchronous
motors supplement the synchronous
servomotors for applications
in the upper power
range （up to 630 kW）.
