Radford, Va. – The Nippon Pulse Linear Shaft Motor is designed and constructed for ultra high-precision applications needing sub-micron resolutions. Because of its design features, the Linear Shaft Motor is more energy efficient and can achieve motion profiles that similar linear motors can’t. 
The design of the Linear Shaft Motor maximizes use of magnetic flux, provides stiffness up to 100-times greater than that of other ironless linear motors, minimizes generated heat and reduces the impact of heat on the work point. It also doesn’t produce Eddy currents, and doesn’t have cogging issues. As a result, the Linear Shaft Motor can achieve sub-micron motion profiles, outperforming competing linear motors.
The Linear Shaft Motor’s cylindrical design provides two inherent benefits. First, the motor is able to use 100 percent of magnetic flux and to use that magnetic flux at maximum efficiency. All available magnetic flux cuts the coils at a 90-degree angle.
Also because of its cylindrical design, and despite being completely ironless, the Linear Shaft Motor provides stiffness up to 100-times greater than all other similar motors.
In part because it has no cogging issues and does not produce Eddy currents, the Linear Shaft Motor also generates less heat than traditional linear motors. As a result, the motor does not dump heat into the work point and thus is able to achieve precise and accurate motion profiles. The lower heat production also comes because the Linear Shaft Motor does not have inherent airflow restrictions.
In tests conducted by the University of Virginia, the Linear Shaft Motor is proven to consume 51.8 percent less energy than a comparable u-shaped motor while performing the same motion, carrying the same load, and producing the same linear force.
