Product Description

Brake motors On request, motors and gearmotors can be supplied with an integrated mechanical

brake. The SEW-EURODRIVE brake is an electromagnetic disk brake with a DC coil

that releases electrically and brakes using spring force. Due to its operating principle,

the brake is applied if the power fails. It meets the basic safety requirements. The brake

can also be released mechanically if equipped with a manual brake release. You will re-

ceive a manual lever with automatic reset. The brake is controlled by a control module

that is either installed in the motor conduit box or the control cabinet.

A significant feature of the brakes is their very short length. The brake bearing end shield

is an integral part of both the motor and the brake. The integrated construction of the

SEW-EURODRIVE brake motor permits particularly compact and sturdy solutions.
