MPS50SL Hardware Manual

Mechanical Specifications and Installation

Figure 2-8:

Stage Orientations

The approximate amount of torque required to turn the drive screw of an MPS50SL series stage can be found
from

Figure 2-9

or the following equation:

Where:

Lead of Screw = see

Table 1-3

Efficiency = .90 for ball screws, .50 for MPS50 lead screws

Reduction Ratio = 49/676 for MPS50SL-DC; 63/2704 for MPS50SL-SM

Moving Mass = 0.2 kg

Preload Torque = 5 Nmm for ball screws, 15 Nmm for lead screws
