Servomotors 1FK7

Compact motor for low power applications with natural cooling

The 1FK7 motors are very compact, permanent-magnet synchronous motors that are available in the High Dynamic and Compact versions. They have a high overload capability and rotatable connectors.

1FK7 synchronous motors - top standard for synchronous motors


1FK7 Compact (CT)
  • The universal motor for a wide range of applications
  • Space-saving installation through very high power density
  • Large range of motors in the shaft heights 20 to 100

1FK7 High Dynamic (HD)
  • The sprinter in the ramp-up time
  • Very high acceleration capability due to low rotor moment of inertia
  • For highly dynamic applications with low load moment of inertia
