Energy management method and system for an electric motor

The invention relates to an energy management method and system for an electric motor (1), preferably a traction motor of an elevator system, wherein an energy manager (4) controls the energy flow between an electric network (3, 3'), energy storage media (2) and the electric motor (1), such that it provides energy to the motor (1) when it requires it; stores energy from the motor (1) in the storage media (2) when it operates according to a mode of operation in which it generates energy, and when said motor is stopped, or its energy consumption is below a limit, stores energy of the electric network (3, 3') in the storage media (2) until reaching a determined threshold (Eth_1).
