3.1 SM 137 D General description and applications
This product is a Synchronous motor with incorporated drive (servomotor) allowing to move parts
of CNC machines (numerically controlled machines such as milling machines, cutting machines,
point to point boring machines, etc...), and it is designed to perform operations on various
materials (for example: wooden materials, metals, marble, glass, etc...). It is designed to be
incorporated in a machine or in partly completed machinery,
and cannot function independently or
outside its range of characteristics.
The servo-motor is made up of a Brushless motor and its drive.
There are three possible types, depending on the type of motor shaft:

flat

key

smooth Ø8
There are three possible types, depending on the speed reduction ratio to the motor shaft:

R = 1:6.25

R = 1:8

R = 1:25
More detailed information about the servo-motor parts is given in paragraph 3.2 “SM 137 D
General overview and main parts” .
