28mm Low-Profile Rotary Positioner with High Force Torque Motor is Mountable on 6-Axis Hexapod |
|
(Nanowerk News) Nanopositioning leader PI expands its PIMag® series of high dynamics linear and rotary positioning systems with a new high-performance rotation stage. | |
High Force Torque Motor, Direct Drive, Optional Brake |
|
The V-610 is equipped with a high-force 3-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.

High Resolution, Velocity and Precision |
|
The torque motor provides maximum angular velocity of 540°/sec (90 RPM). The integrated direct measuring optical encoder resolves angular motion down to 9µrad. In closed-loop operation, minimal incremental motion of 27µrad can be achieved. To hold a position without the need to keep the motor energized, an electromagnetic safety brake is offered as an option. | |
V-610 Specs & Datasheet | |
Low Profile, 1” Aperture, Combination with 6-DOF Motion Systems |
|
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. | |
