1FG1 - Compact, Cost-Effective Servo Gear Motor System

geared servo motor 1fg1

The SIMOTICS S-1FG1 servo gear motors have smaller dimensions, weigh less and have a higher dynamic response than standard induction geared motors. The range of types includes helical, parallel shaft, bevel and helical worm geared motors in the usual frame sizes and speed/torque classes. SIMOTICS S-1FG1 servo geared motors use the same operating heads as SIMOGEAR geared motors.

Benefits

  • Extremely compact design as a result of direct mounting

  • High efficiency

  • Maintenance-free and lubricated for life (exception, worm gearing)

  • Low torsional backlash

  • Low running noise due to helical teeth

  • Suitable for cyclic operation with alternating load and continuous duty

  • Low-cost solution when compared to planetary geared motors

  • Compatible with SIMOGEAR operating heads

  • Degree of protection IP65

Servo Gear Motors with Planetary Gearboxes

High-end gearboxes for maximum machining quality requirements, planetary gearboxes are extremely compact and have a high efficiency of up to 97 %. Thanks to the minimal torsional backlash of ≤ 4 up to ≤ 12 arcmin, the gearboxes are designed for cycle operation for high-precision positioning and machining tasks.

Servomotors with planetary gear units are the optimum choice for motion control applications where high to very high requirements are placed on precision and dynamic performance. Depending on the actual requirement, three different versions are available:

1FK7 with LP+ Gearbox

1FK7 with SP+ Gearbox

1FT7 with SP+ Gearbox
