Motor adapter info

Flexibly coupled: STOBER motor adapters.

The versatile STOBER motor adapter system was specially developed for mounting all common synchronous servo motors and standard motors according to IEC or NEMA-C.

All adapters are designed so that almost any size of motor can be installed or removed in no time at all.

Benefit from the wide range of possible combinations with all STOBER gear unit series. It’s impossible to be more flexible!

Every motor finds its adapter.

Compact and robust: Adapters with EasyAdapt clamp coupling (ME/MEL)

  • Easy and fast mounting of servo motors.
  • Featuring one-piece, rugged clamping coupling with expanding function.
  • Lowest mass moments of inertia for the highest dynamics.
  • Balanced for smooth running without vibration, even at high speeds.
  • Error-free mounting, thanks to exact centering of the motor.
  • For large motors, optionally with an enlarged motor plate (MEL).

Integrated thermal length compensation: Adapters with FlexiAdapt bellow coupling (MF/MFL)

  • Easy and fast mounting of servo motors.
  • Featuring rugged, laser-welded bellow coupling with expanding function.
  • With integrated thermal length compensation – compensates for linear expansion of the motor shaft.
  • Balanced for smooth running without vibration, even at high speeds.
  • Error-free mounting, thanks to exact centering of the motor.
  • For large motors, optionally with an enlarged motor plate (MFL).

For the asynchronous world: Adapters with plug-in or curved tooth coupling (MR)

Easy and fast mounting of standard motors according to IEC and NEMAC-C. Featuring BoWex® curved tooth coupling (flexible shaft connection) for motors with a feather key. With optional backlash-free plug-in coupling for installing smooth-shaft motors.

The flexible one: Square adapters with plug-in or curved tooth coupling (MQ)

  • Easy and fast mounting of servo motors.
  • Featuring backlash-free BoWex® plug-in or curved tooth coupling.
  • Removal of the motor possible in any position.
  • With integrated thermal length compensation – compensates for linear expansion of the motor shaft.
  • Balanced for smooth running without vibration, even at high speeds.
  • With a large motor shaft diameter range.
  • Error-free mounting, thanks to exact centering of the motor.

The special one with integrated spring-loaded brake!

With integrated brake: Adapters with ServoStop plug-in coupling (MB)

  • Easy and fast mounting of servo motors.
  • Electrically actuated spring-loaded brake for dry running integrated in the motor adapter.
  • Featuring backlash-free plug-in coupling (jaw coupling) to hold the axis in any position, even with the motor removed.
  • As a single brake or, in combination with the motor brake, as a redundant brake system.
  • Electrical release monitoring in the terminal box of the motor adapter.
  • Optional manual release.
  • Manual monitoring of wear via air gap checks with a feeler gauge.
  • Four oil drain holes to protect the brake from oiling up in case of leakage.
  • Modular ServoStop design in four sizes, each with up to four braking torques for STOBER servo and right-angle gear units.
