Abstract
A dynamoelectric machine assembly for connection to a system controller. The assembly includes at least one input contact for receiving a control signal from the system controller and a processor coupled to the input contact. The processor is configured to operate the assembly in a pulse width modulation (PWM) mode when the control signal is a PWM control signal and to operate the assembly in a serial mode when the control signal is a serial communication signal.
Claims18
A dynamoelectric machine assembly for connection to a system controller, the assembly comprising:
- an input contact for receiving a control signal from the system controller;
- a processor coupled to the input contact, the processor configured to operate the assembly in a first mode when the control signal is a first type of signal and to operate the assembly in a second mode when the control signal is a second type of signal;
- and
- a four-contact connector for coupling the assembly to the system controller, the four-contact connector including said input contact, wherein the four-contact connector includes a first contact, a second contact, a third contact and a fourth contact, the first contact is the input contact, the second contact is an output contact for sending a data output signal from the assembly to the system controller, the third contact is a power input contact, and the fourth contact is a power return contact;
- wherein the processor includes a capture in and a universal asynchronous receiver/transmitter (UART) pin, and the input contact is coupled to the UART pin and the capture pin to couple the control signal to the UART in and the capture pin, wherein the processor further includes two output pins connected together at a node which is in turn coupled with the output contact of the four-contact connector.
