Title: ELECTRIC BRAKE APPARATUS AND ELECTRIC BRAKE SYSTEM
Abstract:
Provided is an electric brake apparatus that achieves improvement in response and reduction in cost, etc., and, at the same time, is able to reduce copper loss in an electric motor and to reduce power consumption. This electric brake apparatus is provided with a brake rotor (8), a friction member (9), a friction member operation means (6), an electric motor (4), a control device (2), a main power supply device (3), and an auxiliary power supply device (22). The auxiliary power supply device (22) is charged with regenerative electric power from the electric motor (4). The control device (2) has: a backflow power blocking means (26) that prevents the main power supply device (3) from being charged with the regenerative electric power from the electric motor (4); and an auxiliary power supply control device (24) that causes running electric power to be supplied from the auxiliary power supply device (22) to the electric motor (4) when an operation to power the electric motor (4) is initiated while the auxiliary power supply device (22) is being charged with regenerative electric power equal to or beyond a preset voltage level.
