New Release - VSM24-R High Load (Rigid) UHV Rotation Stage
Posted on Thursday 10th October 2024 at 9:00
The VSM24-R is a new addition to AML's VSM range of ultra high vacuum compatible stages. Featuring high specification bearings, the VSM24-R has a high 250 kg centred load capacity. Its rigid bearing arrangement also makes it ideally suited for applications that feature large off-centre loads. The VSM24-R was adapted from a recent custom stage design which we discussed in a recent blog. Click here to read about that stage and its application.
VSM24-R
Vacuum: 1x10-10 mbar
0.005 ° resolution per step
250 kg centred load capacity
D42.2 UHV stepper motor
Bakeable to 150 °C
The large design of the VSM24-R enables its enhanced specification such as the inclusion of AML's D42.2 UHV stepper motor to achieve a max torque of 15 Nm. The stage has a 212 mm diameter table so that it can coordinate with larger loads and samples. The VSM24-R is constructed with a combination of stainless-steel and UHV-prepared aluminium. Weight-saving features are seen throughout the stage. These are designed to reduce minimise the mass of the stage whilst retaining the strength required for handling high loads.
Limit switches:
The limit switch option adds a module with two of AML's VLS1 UHV compatible limit switch. These limit the travel of the stage to 0-360°. With the SMD4, the limit switches on the stage can be used with the homing function to drive the stage to either switch. The limit switches also provide a repeatable position from which future movements can be coordinated from.
Encoder:
Incremental and absolute encoder options available.
Anti-backlash spring:
The anti-backlash spring option adds a module to the stage which improves backlash to <0.005° and repeatability to 0.025° (bi-directional) and 0.02° (uni-directional). With the anti-backlash module fitted, the travel range of the stage is limited to 0-360°.
Like all AML stages, the VSM24-R can be modified to suit specific needs and applications. If modifications are required, please contact us to discuss this.
