The invention discloses a motor for an automobile brake system. The motor comprises a motor assembly and a hydraulic integrated block. The motor assembly is installed on one side of the hydraulic integrated block. The motor assembly comprises a motor shell and a stator arranged in a center of an inner portion of the motor shell. An outer rotor is arranged on an outer side of the stator; a ball screw pair is arranged in the center of the stator, one end of the stator is connected with a servo cylinder piston, the servo cylinder piston is inserted into a servo cylinder assembly installed on oneside of the hydraulic integrated block, an outer rotor drives a lead screw of the ball screw pair to rotate together, and a nut connected to the lead screw in a sleeving mode moves linearly to drive the stator and the servo cylinder piston to move linearly. The servo cylinder assembly is arranged in the motor, an integration degree is high, and a size is small.
