Motor control systems for multiple motor drives

A motor control system, comprising:

• a resolver configured to output resolver signals;
• a plurality of motor drives, each motor drive configured to drive a segmented motor;
• and a resolver signal splitter connected between the resolver and the plurality of motor drives to split the resolver signals from the resolver to provide each motor drive with the resolver signals wherein the resolver signal splitter includes a sine input and a cosine input, wherein the resolver signal splitter is configured to connect to a signal generator to receive an input excitation signal, and to split the excitation signal to output the excitation signal to each of the motor drives and/or to output the excitation signal to the resolver.

A resolver signal splitter configured to connect between a single resolver of a segmented motor and a plurality of motor drives, the signal splitter configured to split resolver signals from the single resolver to provide each motor drive with the resolver signals to drive each segment of the segmented motor, wherein the resolver signal splitter includes a sine motor drive output assembly for each motor drive connected to sine input and a respective motor drive, wherein the resolver signal splitter includes a cosine motor drive output assembly for each motor drive connected to cosine input and a respective motor drive.

A method, comprising:

• receiving a resolver signal from a single resolver of an electric motor;
• and splitting the resolver signal to output a common resolver signal to a plurality of motor drives, wherein the resolver signal splitter includes a sine motor drive output assembly for each motor drive connected to sine input and a respective motor drive, wherein the resolver signal splitter includes a cosine motor drive output assembly for each motor drive connected to cosine input and a respective motor drive.
