Stober ServoStop

Stober ServoStop is a compact and reliable braking system that can be integrated into a variety of servo motors. It provides safe braking during emergency stops or power failures, making it an ideal solution for applications where safety is critical.

The ServoStop is easy to install and can be mounted in any position except EL6 motor down. It features double lip FKM radial seals to protect the brake disk from oil, and the motor shaft can be disassembled without removing the load.

The ServoStop is available in a range of sizes to accommodate different torque requirements. It is also highly efficient, with an efficiency of up to 90%.

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.
