1. A heating, ventilating, or air conditioning (HVAC) system comprising:
- a blower motor assembly comprising a housing, an electric motor, a motor controller, and a memory device positioned within the housing for permitting a plurality of external devices to store non-transient data in and retrieve data from the memory device and positioned in the housing, the memory device being partitioned into at least a first portion, a second portion, and a third portion, wherein the first portion of the memory device is operable to be written to and read from only by the motor controller for operating the electric motor;
an HVAC system controller for controlling the blower motor assembly and operable to write data to and read data from only the second portion of the memory in the blower motor assembly; and
a handheld computer device for performing HVAC system configuration and troubleshooting and operable to read data from the second portion and to write data to and read data from the third portion of the memory in the blower motor assembly.

Abstract
A method is provided for storing data from an external device in a dynamoelectric machine assembly (i.e., an electric motor or generator). The dynamoelectric machine assembly includes a memory device and a processor for controlling operation of the dynamoelectric machine assembly in response to commands from an external device. The method includes receiving a command from the external device to store data in the memory device of the dynamoelectric machine assembly, and storing the data in the memory device in response to the command. Dynamoelectric machine assemblies, external devices and systems suitable for use in the provided method are also disclosed.
