Sound energy level

SIMOGEAR geared motors have noise levels below the permissible noise levels defined for
gearboxes in VDI guideline 2159 and for motors in IEC 60034-9. Interaction with gearboxes
causes the motor noise values L
The circumferential velocity of the motor pinion has a significant influence on the additional
gearbox noise level. As a consequence, higher speeds or lower ratios result in higher noise.
SIMOGEAR geared motors provide a decisive advantage here, since the motor plug-on pinion
allows transmission ratios of up to 12 in the input stage.
