Annular Motor Design - Oil and Gas
PROBLEM: An oil field application required a rotary motor for downhole actuation of a proprietary device.Requirements included a design with a large open bore through the center and use of a rechargeable battery pack that would be recharged through periodic inductive charging from the surface.
RESULTS: Using in-house proprietary motor topology, PCDworks created and modeled a number of candidate designs. Subsequently, the motor designs were paired with a number of actuator designs to demonstrate effectiveness across multiple applications. A novel new motor was developed and prototyped that produced large amounts of torque with a small form factor and low power consumption.
