Energy storage circuit for electric motors, especially asynchronous or synchronous servo motors, has voltage detection stage that detects motor generator state; storage device is charged up as result

摘要

The energy storage circuit (6) has a stage for voltage detection for connection to the electric motor (4) via an intermediate circuit of a frequency inverter or servo-actuator (2) and an energy storage unit connected to the voltage detection stage, which detects a generator state of the electric motor and the energy storage device is charged up as a result.
