ELECTRIC BRAKE DEVICE

Provided is an electric brake device that can suppress increase in power consumption and that can improve responsiveness. This electric brake device includes: a brake rotor; a brake pad; an electric motor (2); a linear motion mechanism configured to convert a rotary motion of the electric motor (2) into a linear motion so as to be transmitted to the brake pad; a controller (9) to control the electric motor (2); and a brake command (40) device to send a braking force command to the controller (9). The controller (9) includes: an emergency braking detector (41) to detect an emergency braking request; a steady state controller (46) to perform braking in a steady state; and a flux weakening controller (42) to perform flux weakening control. The flux weakening control is performed when the emergency braking detector (41) detects an emergency braking request.
