We have developed a transverse flux linear switched reluctance motor (TFLSRM) in which 12 primary-side poles, each composed of four sectors, boost efficiency over the whole operating range. Each sector can operate independently, enhancing the robustness of the system by providing fault tolerance. We present a standard design method for the machine based on a power output equation related to the machine dimensions, air gap, force, efficiency, operating velocity, and required voltage. We illustrate the procedure by designing a sector for a three-phase, 250 W prototype TFLSRM. The method uses finite-element analysis to calculate the flux density, thrust force, and normal force versus position and current prior to construction of the prototype. Calculated and experimental results match within 5, validating the design procedure.
