Printed linear motors

1st Quarter 2014 Electrical switching & drive systems & components

The groundbreaking new UPL series of printed linear motors developed by Schaeffler Group’s INA – Drives & Mechatronics (IDAM) has outstanding performance and energy efficiency, with low costs and an optimised price/performance ratio. The innovative technology prints the coils of the motor layer by layer using conventional circuit board material. Multiple layers of copper are applied and wired together to form a printed coil. This type of motor, in which the forcer moves in a U-shaped secondary part, is known as an ironless linear motor.

The use of an ironless primary part that exerts no permanent forces of attraction on the secondary part also means that the current rise times are short. In addition, the force to mass ratio is balanced. The high feed force with a relatively small moving mass makes rapid acceleration possible while maintaining extremely high path accuracy.

The new linear motors also display outstanding static and dynamic load rigidity, have no cogging forces. They are extremely reliable and have a long operating life. Machine-based manufacturing means that an outstanding level of quality is achieved. The printed linear motors have a small inherent mass, which makes them ideal for vertical mounting applications.

The UPL linear motors are easy to adapt and can therefore be optimally adjusted to suit individual customer requirements. They are ideal for applications requiring excellent path and positioning accuracy, outstanding dynamics, the shortest possible response times and a compact design. They are available in lengths of 34 to 258 mm with a force range of 10 to 240 N.
