Short response
times
A primary feature of the brake is the patented two-coil system. This system consists of
the accelerator coil (BS) and the holding coil (TS). The special SEW-EURODRIVE brake
control system ensures that, when the brake is released, the accelerator coil is switched
on first with a high current inrush, after which the holding coil is switched on. The result
is a particularly short response time when releasing the brake.
The principle of the two coil system also reduces back EMF so that the brake is applied
more rapidly. The result is a reduced stopping distance. The brake can be switched off
in the DC and AC circuit to achieve particularly short response times when applying the
brake, for example in hoists.
