Method and apparatus for diagnosing motor damping network integrity |
摘要 |
An apparatus for diagnosing motor damping network integrity, the motor damping network configured for selective short-circuiting of the windings of a motor in a motor control system. The apparatus includes a motor controller with a motor drive portion thereof electrically isolated from the windings of the motor. A resonant network is based on the windings of the motor, the damping network, and a remaining non-isolated portion of the controller. An amplifier circuit applies an excitation signal to the resonant network. A detector circuit detects a response of the resonant network based on the excitation signal. A state of the damping network is determined based on the response.
