Low-profile rotary positioner can be mounted on six-axis hexapod

PI is expanding its PIMag series of high-dynamics linear and rotary positioning systems with a new high-performance rotation stage. The V-610 is equipped with a high-force three-phase torque motor direct incremental encoder for position feedback and closed-loop operation. Direct drive torque motors do not require gears and mechanical components, eliminating friction in the drive train. Despite its compact size, the ironless motor provides a peak torque of 1.2Nm (10.6 in-lbf). Ironless motors provide smoother running with better velocity control due to the lack of cogging effects caused by permanent magnets.

The torque motor provides maximum angular velocity of 540degrees/sec (90 RPM). The integrated direct measuring optical encoder resolves angular motion down to 9urad. In closed-loop operation, minimal incremental motion of 27urad can be achieved. To hold a position without the need to keep the motor energised, an electromagnetic safety brake is offered as an option.

The V-610 features a very low profile of only 28mm (1.1 inch) allowing integration into tight spaces. The clear aperture of 25mm (1") is an advantage in transmissive-light applications. The V-610 can also be combined with PI's H-811 hexapod 6DOF parallel positioner, adding unlimited rotation to this compact 6-axis alignment system. An adapter plate for optical tables is also available.

A variety of precision motion controllers are offered, from modular to bench top devices. For the highest performance, PI recommends the ACS product line of EtherCat compatible precision motion controllers.

PI has in-house engineered solutions with over 4 decades of experience working with customers to provide products that meet application demands, and can quickly modify existing product designs or provide a fully customized OEM part to fit the exact requirements of the application.
