10.5.2 ServoStop motor adapter with brake (MB)
In this chapter, you will find the description and technical data of the motor adapter with brake.
10.5.2.1 Properties
• Electrically actuated spring-loaded brake for dry running
• Featuring backlash-free plug-in coupling (jaw coupling) for easy removal of the motor with the axis
braked in any position
• Electrical release monitoring in the terminal box of the motor adapter
• Manual monitoring of wear via air gap checks with a feeler gauge
• As a single brake or together with the motor brake as a redundant brake system
• Manual release (optional)
• Radial shaft seal rings made of FKM with two sealing lips
• Four oil drain holes to protect the brake from oiling up in case of leakage
• Fast and easy motor attachment

10.5 Product description 10 K helical bevel gear units

10.5.2.2 Brake
A quiescent current brake is integrated into the motor adapter. It has the function of a holding brake. Braking from full speed, e.g. in case of a voltage drop or an emergency off in hazard situations, is still possible.
The brake can be used as a single brake or together with the motor brake as a redundant brake system.
Function
The brakes installed in the motor adapter are electrically actuated spring-loaded brakes for dry running. In
the de-energized state, braking takes place using spring force. The brake is released by an electromagnetic
DC coil before the motor is switched on. The switch-on time t2B (release time) is the time until the anchor
plate releases from the axially moving brake disc and is magnetically held to the coil body. In this state, the
brake is released and the coupling hub can rotate. In order to switch off (motor and brake), the residual
magnetic flux of the iron parts (anchor and coil body) must be reduced; the associated time t11B until the
start of torque generation is defined as a response delay when linking. The link time t1B is the time until the
braking torque has built up to the nominal braking torque.
Manual release
Optionally, the brake can be equipped with a manual release.
Pressing the manual release deactivates the electronic actuation of the brake. Before pressing the manual
release, you must establish the safety of the machine (e.g. protection against falling).
10.5.2.3 Electrical connection
• Terminal box (standard)
• Plug connector (optional, not possible in combination with release monitoring)
10.5.2.4 Monitoring
For monitoring the brake system, there are generally two options:
• Manual monitoring of wear via air gap checks with a feeler gauge
• Electrical release monitoring in the terminal box with a non-contact and wear-free proximity switch

10.5.5 Installation conditions
Hollow shaft
The hollow shaft hole tolerance is ISO H7. The tolerance of the machine shaft must be ISO k6.
Take care to align the machine shaft with the gear unit hollow shaft when attaching the gear unit.
Maximum deviation ≤ 0.03 mm.
For simpler assembly and disassembly of the machine shaft, the hollow shafts are equipped with a spiral
groove (as a grease deposit).
A hardened, threaded keeper plate is included in the scope of delivery. You also have the option to order
the hollow shaft without a keeper plate.
Hollow shaft with shrink ring
The tolerance of the hollow shaft hole is ISO H7.
The machine shaft must be executed as follows:
Gear unit type Tolerance
K1 to K6 ISO h9
K7 to K10 ISO h6
Select a material for the machine shaft with a permitted surface pressure of p ≥ 325 N/mm2
.
Possible materials:
• C45E +QT
• 42CrMo4
Fastening the gear units on the machine side using the pitch circle diameter
The specified torques and forces only apply when gear units are fastened on the machine side using screws
of strength class 10.9. In addition, the gear housings must be adjusted at the pilot. The machine-side fit
must be H7.

Since the lubricant filling volume of the gear unit depends on the mounting position, the mounting position
must be specified when ordering.
10.5.7 Lubricants
STOBER fills the gear units with the amount and type of lubricant specified on the nameplate. The filling volume and the structure of the gear units depend on the mounting position.
Only install the gear units in the intended mounting position! Reposition the gear units only after consulting
STOBER. Otherwise, STOBER assumes no liability for the gear units.
You will receive lubricants for use in the food industry upon request.

It is the most convenient and reliable method of drive selection, as the entire torque/speed curve of the application is displayed and evaluated here in the curve of the geared motor.
In this chapter, only limit values for specific operating points can be taken into consideration for manual
drive selection.
An explanation of the formula symbols can be found in the chapter Formula symbols.

10.6.3 Permitted breakdown torques at the gear unit input
For a horizontal mounting position of the motor, verify that the permitted breakdown torque at the gear
unit input is not exceeded before installation on a STOBER gear unit. You can find information for how to do
that in this chapter.
Calculate the actual breakdown torque as follows:

10.6.4 Radial shaft seal rings
Leak-proofness
Our gear units are equipped with high-quality radial shaft seal rings and checked for leaks. However, a leak
cannot be fully ruled out over the length of use of a gear unit. If you use a gear unit with goods incompatible
with the lubricant, you must take measures to prevent direct contact with the gear unit lubricant in case of a
leak.
10.6.5 Oil expansion tank
The gear units have a higher fill level in mounting position EL5. The oil expansion tank prevents oil from escaping out of the gear unit.
Notes
• We recommend using an oil expansion tank in mounting position EL5 (additional cost) for fast running
gear units with an input speed n1 > 1750 rpm and gear ratios i < 20.
• The oil expansion tank can only be used with certain sizes; see the chapter Oil expansion tank
