2.5.1 Type of Motor
The motors employed in this robot are shown below. When you place an order for
a new motor, make sure of the robot model (TH650A), axis name, type and our
drawing number according to the following table.
As the input gears are used for the axes 1 and 2, a key is provided between each
motor shaft and input gear. At motor replacement, key alignment is also necessary.
It is recommended, therefore, that the input gear be replaced at the same time with
motor replacement.
For the axis 3 also, a pulley on the motor side is driven by means of the key.
For our drawing numbers on the input gear and pulley and type of the key, also see
the table below.
