The use of liquid nitrogen as coolant allows an in- crease in the power-density of copper-wound electrical machines. This work illustrates the design of a high thrust-density cryogenic copper-wound PM linear tubular actuator. The actuator model was analyzed and a design optimization procedure was envisaged. A short-stroke 160 N actuator was built. Standstill tests were carried out on a customized test rig. The experiments showed that both the shear stress and the ratio thrust to copper loss are advantageously higher than in conventional machines.

Abstract: | The use of liquid nitrogen as coolant allows an in- crease in the power-density of copper-wound electrical machines. This work illustrates the design of a high thrust-density cryogenic copper-wound PM linear tubular actuator. The actuator model was analyzed and a design optimization procedure was envisaged. A short-stroke 160 N actuator was built. Standstill tests were carried out on a customized test rig. The experiments showed that both the shear stress and the ratio thrust to copper loss are advantageously higher than in conventional machines. |
