An electric anti-lock brake system for outward-rotation type automobile drive motors comprising a power supply (3) and a pulse current generator (4). The power supply (3) electrically connects to an outward-type automobile drive motor (2) through a pulse current generator (4). The pulse current generator (4) outputs a pulse current to the outward-type automobile drive motor (2), the current changing from weak to strong in strength and from low to high in frequency and generating a reverse magnetic field for braking. The electric anti-lock brake system for outward-rotation type automobile drive motors prevents brakes from locking, and enables electric anti-lock braking.
