Abstract
An electrical brake with a holding function, in particular for an electromechanical brake in motor vehicles, is described. The brake contains an electric motor having a holding brake function. To generate the holding brake function, an electric motor with salient stator poles and rotor poles is provided. The motor is acted upon by a defined holding current in such a way that the poles of the motor thereby are brought into a locked position and held there, or are held in a locked position. Advantageously, after activation of the holding brake function and after a locked position has been reached, the current delivered to the motor for braking is very substantially decreased. The electrical brake can optionally act on the brake caliper with a spindle and a linkage, the electric motor driving and braking the spindle.
