Integrated Product

DGII Series is integrated product that combines a hollow rotary table and a stepping motor. Actuator inside serves as a reduction gear structure ( reduction ratio 18 ) , it can be a high output drive.

Reduction in Design Time

Equipment tables and arms can be installed directly on the output table.

This saves you the hassle and cost of designing an installation mechanism,

arranging necessary mechanism parts, adjusting the belt tension, etc., when

mechanical components such as a belt and pulley are used for installation.

High Load and High Rigidity

The standard type uses a cross-roller bearing on the output table bearing, which allows for both high load and high rigidity.
● Maximum Permissible Axial Load 4000 N
● Maximum Permissible Moment 100 N·m
<Example Operation>
Product Name : DG200R-AZAC-1
Power-Supply Input : 230 VAC
Load Mass 91 kg (6 load pieces + table)
: Load 10 kg/piece × 6 pieces
: Table 31 kg
(Diameter 500 mm, thickness 20 mm, iron)
Overhang Distance : 160 mm
Installation Direction : Horizontal

● High Rigidity
[Load Moment] When a 10 kg load is placed 160 mm from the center of the table, the moment is 15.7 NEm. 10 kg ~ gm/s2 ~ 0.16 m 15.7 NEm The permissible moment of the DG200R is 100 NEm, so this is within the permissible value. œ High Rigidity [Axial Load] The axial load is: table + load (31 kg + 10 kg) ~ gm/s2 402 N The permissible axial load of the DG200R is 4000 N, so this is within the permissible value.


Relationship Between Load Moment and Displacement when Distance L=200 mm from Center of Table The larger the frame size, the received permissible moment increases, but the displacement caused by the load moment decreases.
