Abstract

An interface module is operable to download data from an electrical machine. The interface module includes a cable for transferring data, the cable having a first connector at a first end thereof, a circuit board having a programmable device electrically coupled in circuit to the cable, and a memory connected to the circuit board and configured to store data related to the operating characteristics of the electrical machine.

Claims

1. A method of configuring an electrical machine with an interface cord including

a first connector,

a cable having a first end and a second end, the cable coupled to the first connector at the cable first end, and

a circuit board coupled to the cable at the cable second end, the circuit board including a second connector and a programmable device having a memory, the programmable device electrically coupled in circuit between the cable second end and the second connector, the method comprising:

coupling one of the first connector and the second connector of the interface cord to a first electrical machine; and

downloading data from the electrical machine to the memory;

decoupling the one of the first connector and the second connector with the electrical machine;

coupling the one of the first connector and the second connector with a second electrical machine; and

uploading the data to the second electrical machine.

2. The method as claimed in claim 1, wherein the first electrical machine includes a motor assembly and a motor controller with a third connector, wherein the method further includes engaging the third connector with one of the first connector and the second connector of the interface cord.

3. The method as claimed in claim 1, further comprising

receiving a first signal having a first pin configuration,

translating the first signal to a second signal having a second pin configuration, and

communicating the second signal to the electrical machine.

4. The method as claimed in claim 3, wherein receiving the first signal includes receiving the first signal from an external controller.

5. The method as claimed in claim 3, wherein the downloaded data includes characterization data for operating the electrical machine.

6. An electrical machine assembly for an HV AC system including a blower and an external controller, the electrical machine assembly comprising:

an electrical machine coupled to the blower for moving the blower, the electrical machine including

a motor assembly having a stator and a rotor, and

a motor controller connected to the motor assembly and having a first connector;

a second connector coupled to the external controller;

a cable connected to the second connector;

a third connector coupled to the cable and engaging the first connector; and

a circuit board electrically coupled in circuit with the second connector, the cable, and the third connector, the circuit board including a processor and a memory, the memory including characterization data and being configurable to receive characterization data from the motor controller.

7. The electrical machine assembly as claimed in claim 6, wherein the received characterization data includes data related to a configuration of the HV AC system.

8. The electrical machine assembly as claimed in claim 6, wherein the circuit board is in circuit between the first and second connectors.

9. The electrical machine assembly as claimed in claim 6, wherein the cable includes a first end directly coupled to the circuit board.
