Interface cord and system including an interface cord

1. A method of operating 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 memory including characterization data for operating the electrical machine, the method comprising:

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

uploading the characterization data to the electrical machine; and

operating a blower with the electrical machine as a result of uploading the characterization data.

2. The method as claimed in claim 1 , wherein the 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 1 , further comprising downloading characterization data from the electrical machine to the programmable device.

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 selectively upload characterization data to the motor controller.

7. The electrical machine assembly as claimed in claim 6 , wherein the uploaded characterization data includes data related to a configuration of the HVAC 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.
