Abstract
A method and apparatus provide for reduced cost and complexity in managing an intelligent motor in an architecture in which information is transferred between a power management device and the intelligent motor. The information may be used by an embedded processor of the motor to provide diagnostics and/or prognostics of the motor, machinery operating in conjunction with the motor, and/or a process in which the motor may be configured to operate. The power management device may remotely determine motor current information that is used by the intelligent motor to self-diagnose the intelligent motor using the motor current information.
