SIMOTICS S-1FK7 servomotors with series SP+ planetary gearbox


Picture SIMOTICS S-1FK7 servomotors with series SP+ planetary gearbox

The SIMOTICS S-1FK7 motors can be supplied in combination with planetary gearboxes as compact, coaxially designed drive units. The gearboxes are flanged directly to the drive end of the motors. The servo planetary geared motors with IP64 degree of protection are designed for operation without external cooling and the heat is dissipated over the motor surface. The geared motors have high maximum torques and permit high radial and axial forces at the shaft extension.

A brief summary of its strengths

  • Power transmission from the central sun wheel via planet wheels

  • No shaft deflections in the planet wheel set due to symmetrical force distribution

  • Very low moment of inertia and hence short acceleration times of the motors

  • Output shaft bearings dimensioned for high cantilever and axial loads with preloaded tapered-roller bearings

  • The gearboxes are connected to the motor shaft via an integrated clamping hub

  • Output shaft of gearbox exactly coaxial with the motor

  • The gearboxes are enclosed (seal between gearbox and motor) and filled with oil at the factory

  • Small dimensions

  • Low weight

Typical Uses

In general mechanical engineering, wherever coaxial drive units are used, e.g. in

  • Packaging machines

  • Wood, glass and ceramic processing machines

  • Plastic injection molding and foil stretching machines

  • Handling systems

  • Machine tools

  • All kinds of auxiliary axes
