An electric motor system, which may be included in an aircraft, includes a multi-phase motor, a multi-phase inverter circuit, and a plurality of motor brake switches. The multi-phase inverter circuit is coupled to each phase of the multi-phase stator and is adapted to be coupled to a high-side voltage node and a circuit common node. Each motor brake switch is associated with, and is connected in series between, the circuit common node and a different one of the phases. Each motor brake switch is configured to be in an open state when energized and in a closed state when deenergized. When the motor brake switches are in the open state, the motor brake switches do not connect the associated phases to the circuit common node, and when the motor brake switches are in the closed state, the motor brake switches connect the associated phases to the circuit common node.
