MARH Series

The MARH series turntable is driven by a frameless motor. Since the motor is non-contact, there is no need to maintain brushes or gears. The turntable is supported by NSK angular contact ball bearings and is equipped with incremental optical encoders, which enables the MARH series turntable to achieve stable and high-performance operation at a low cost.

Remarks:

The default test point position is 25mm above the table, and the single-axis index and the performance index of the multi-axis system are related to the actual load and the position of the working point;
For higher demand, it needs to be equipped with Heidelhain grating ruler and linear amplifier;
No load, need to configure the corresponding power of the linear amplifier,
The payload specification assumes that the payload is centered on the axis;
In order to ensure the implementation and repeatability of the specification over a long period of time, the ambient temperature must be controlled within a range of 1°C per 24 hours.
