2.1 General notes on product description

Power and torque The power and torque ratings listed in the catalogs refer to mounting position M1 and

similar mounting positions in which the input stage is not completely submerged in oil.

In addition, the gearmotors are assumed to be standard versions with standard lubrica-

tion and under normal ambient conditions.

Please note that the motor power shown in the selection tables for gearmotors is subject

to selection. However, the output torque for the desired output speed is essential for the

application and needs to be checked.

Speeds The quoted output speeds of the gearmotors are recommended values. You can calcu-

late the rated output speed based on the rated motor speed and the gear unit ratio.

Please note that the actual output speed depends on the motor load and the supply sys-

tem conditions.

Noise levels The noise levels of all SEW-EURODRIVE gearmotors and motors (brake motors) are

well within the maximum permitted noise levels set forth in the VDI guideline 2159 for

gear units and IEC/EN 60034 for motors.

Coating Gear units, motors and gearmotors from SEW-EURODRIVE are painted with "SEW

blue" as standard. Special coatings are available on request.

Surface and

corrosion

protection

If required, all SEW-EURODRIVE gear units, motors and gearmotors can also be

supplied with special surface protection for applications in extremely humid and

chemically aggressive environments.

Weights Please note that all weights shown in the catalog exclude the oil fill for the gear units and

gearmotors. The weights vary according to gear unit design and gear unit size. The

lubricant fill depends on the mounting position selected, which means that in this case

no universally applicable information can be given. Please refer to "Lubricants" in the

"Design and Operating Notes" section for recommended lubricant fill quantities

depending on the mounting position. The exact weight is given in the order confirmation.

Air flow and

accessibility

The gearmotors/brake motors must be mounted on the driven machine in such a way

that both axially and radially there is enough space left for unimpeded air flow and for

the purposes of maintenance of the brake and MOVIMOT

inverter, if necessary.

Please also refer to the notes in the motor dimension sheets.
