Servomotor The servomotor essentially comprises the motor with an integrated solenoid
brake and a position sensing system. The solenoid brake prevents motion of
the carriage at standstill.
The solenoid brake is closed when deenergized, i.e. the armature is pulled
against the solenoid brake by a permanent magnetic field. When current flows
through the solenoid brake, the permanent magnetic field decays and the ar-
mature is released.
The servomotor is fastened on the side of the gear unit. The motor and control
cables are connected by means of the connectors.
Gear unit The motor speed is reduced by the gear unit and transferred by the pinion to
the rack. The gear unit is fastened to the carriage via an intermediate plate.
The backlash is adjusted by means of the eccentric on the intermediate plate.
The gear unit is lifetime-lubricated. The rack and pinion are greased.
3.1.4 Description of the energy supply system
The energy supply system consists of the energy supply chain, the connector
plate and a driver. The energy supply chain contains the supply lines for the
robot and the energy and fluid supply. These supply lines are required for op-
erating the linear unit and the robot and for any connected tools (e.g. spot weld
gun). The energy supply system is supported in guides. It is fastened to the
floor via the connector plate and to the carriage via the driver. The attachment
on the carriage is dependent on the length of the energy supply chain. The
length of the energy supply chain depends on the travel of the carriage.
Figure (>>> Fig. 3-5) below shows the two variants for attaching the energy
supply system. These depend on the travel (H) of the carriage and on the
chain width (BK).
