The invention provides an electric brake, and belongs to the technical field of automobiles. The problem that existing clearance self-adjusting devices are complex in structure is solved. The electricbrake comprises a driving motor, a screw transmission structure and a friction plate; the driving motor can drive the screw transmission structure to push the friction plate to abut against a brake disc of a vehicle; the driving motor can be driven by a controller to serve as a clearance compensation device to compensate the brake clearance of the electric brake, specifically, after the driving motor drives the screw transmission structure to start braking, a sensor is adopted to collect the braking force T1 borne by the friction plate when the friction plate abuts against the brake disc; thecontroller compares the collected braking force T1 with the preset braking force value T2, and when T1 is equal to T2, the position where a rotor of the driving motor is located is set to be the braking demarcation point; and after braking is finished, the braking demarcation point is used as an initial point, and the set reverse rotating number of turns N2 of the driving motor is controlled. Theelectric brake has the advantages of being simple in structure, high in control precision and good in braking effect.
