Stober ServoStop Installation guide

  • Hello! I've reviewed the provided document about the STOBER ServoStop Braking System. It details the system's integration into the motor adapter, its safety features, and mounting options. I'm ready to answer your questions about the ServoStop system, its installation, and its technical details.
  • What is the purpose of the ServoStop braking system?
    What type of seals are used to protect the brake disk?
    In what positions can the ServoStop units be mounted?
    What should be done before installing the motor coupling?

Optional ServoStop® Braking
System (C, F, K, P/PA, PH/PHA, PK, PHK)
The integration of a backlash-free brake into the
motor adapter makes a very compact means to
provide safe braking during emergency stops or a
power failure. The addition of double lip FKM radial
seals protects the brake disk from oil. Units can be
mounted in any position except EL6 motor down.
Motors can be disassembled without removing the
load.
Important: Clean the motor shaft with degreaser to
remove any lm of oil or grease.

Step 1 Install the motor coupling into the motor
sha.
Carefully slide the coupling onto the
motor shaft with allen head screws
facing outward. When installed, the
coupling should be located as close
as possible to the hub of the motor.
To secure the coupling use a torque
wrench to tighten the three (3) allen
head screws to the recommended
torque in Table 1.

Step 2 Install the motor.
For ease of installation, place
the coupling insert onto the
coupling.
With the coupling and insert
installed, guide the motor shaft into the gearhead
brake. Support the gearhead during installation
as some maneuvering may be required to attain
correct alignment with the brake coupling.
Install the motor ange bolts and
with a torque wrench tighten to
the recommended tightening
torque in Table 1.
