A matrix-connected driver for multiple two-phase motors includes circuit rows and columns of input and output connections for the phases of networked two-phase motors. Phases of multiple motors share the same input line and phases of multiple motors share the same output line but no motor phase shares both the same input and the same output. Buffers that may be transistors power each input and output line. The input and output lines may be alternatively positively powered high or grounded low using the buffers. In this fashion individual phases may be singly powered using selected pairs of the buffers without causing the other phases to be powered whether high or low. A processor such as a microprocessor drives the buffers. The usage of common input and output lines or otherwise referred to as columns and rows allows the same number of motors to be single phase mode driven with much less wires. The device is particularly effective for driving multiple motors whereby the electronics are not in the same environment as the motors. This may be motivated due to extreme temperatures, radiation, or remoteness of the environment, so that the chance of a requirement to access the hostile environment will be minimized.
