First Claim
Patent Images
1. A controller for controlling a plurality of motors in a fluid handling system, comprising:
- a connector input/output port that communicates with at least one sensor in the fluid handling system to obtain sensor data;
at least one digital signal processor (DSP) and gate driver interface that evaluates the sensor data and generates a control signal based on the sensor data;
at least one commutation module in communication with said at least one DSP and gate driver interface, wherein said at least one commutation module controls at least one motor based on the control signal;
a local power supply that powers the motor; and
the local power supply is a DC backup power supply, and wherein said at least one DSP and gate driver switches to the DC backup power supply to supply power to said at least one motor in the event of a main power failure.

Abstract
An integrated skid system integrates the functions of multiple skids into a single skid to reduce the skid footprint and the complexity of the overall system. A multi-motor controller monitors the devices on the integrated skid to maintain proper temperature, pressure and current draw in the devices. Base on this information, the multi-motor controller can make decisions on faults and fault accommodation and communicate with a main controller regarding the operating states of the skid devices via a single serial or Ethernet-type connection.
