Permanent magnet brake PMB2-1

Starting current* Min. torque (residual torque)* Max. permissible slip power** Max. permissible operating temperature Rotor moment of inertia Manual torque adjustment via ring on the outer diameter Latching function at 20° intervals Torque constant approx. 0.04 Nm per 20° *** Corresponds to the bearing friction (dependent on temperature and speed). Value determined at room temperature (22°C). Taking into account the maximum permissible operating temperature, the brakes may also be overloaded momentarily. *** Torque changes in the medium torque range are almost linear. Linearity is not fully guaranteed in the upper and lower ranges. * The brake can be adjusted both when stationary and in operation. If the torque is reduced while at standstill, a low level of cogging 8 2 3 4 5 6 7 torque may occur.
