S77 SF77 Helical Worm Geared Motor SA77 SAF77 Speed Reducer

Product Description

S77 SF77 Helical Worm Geared Motor SA77 SAF77 Speed Reducer with motor power 0.55kw, 0.75kw, 1.1kw, 1.5kw, 2.2kw, 3kw, 4kw, 5.5kw and 7.5kw, max. permissible torque up to 1270Nm, transmission ratios from 9.96 to 241.09. Mounting mode: foot mounted, flange mounted, short flange mounted, torque arm mounted. Output shaft: solid shaft, hollow shaft (with key, with shrink disc and with involute spline). Helical worm gearmotors are helical/helical-worm combinations, they are more efficient than normal RV worm gearboxes. Due to their outstanding efficiency, these drives can be used in every industrial sector and tailored to individual torque and speed requirements. The reduction ratios afforded by the helical-worm gear stage and the low noise levels during operation make these gearmotors ideal low-cost solutions for simple applications.

Applicable Motors include Y series IEC standard and IE2 high efficiency single and double speed motor, YVP, YVPEJ, YEJ, YDEJ series variable frequency and brake three-phase asynchronous motor, YZP, YZPEJ, YZRE series three-phase asynchronous motor for crane and metallurgical applications, YB, YBEJ, YBPT, YFB series explosion-proof three-phase asynchronous motor, YGa, YGb series table roller motor, Synchronous motor, DC motor, servo motor.
