YQS
YQS helical-worm geared motors
The YQS range are right-angle geared motors that combine an input helical stage with a worm stage at the output. Seven sizes, 37 to 97, cover 0.18–22 kW input power and permissible torque up to 4000 Nm. Foot, flange, hollow-shaft, short-flange and torque-arm versions are available.

- Shaft-input version without motor
- Combination with an R helical unit (S..R..) for very high ratios and low output speeds
- Six mounting positions M1–M6, terminal box at 0°/90°/180°/270°
- Y-series motors are supplied with IP54 protection unless specified otherwise
