STANDARD SPRING-APPLIED BRAKE

COMBISTOP 38

The COMBISTOP type 38 is a closed current spring-applied brake. It has been manufactured by KEB for over 50 years and is used throughout the world in a wide range of applications. The brake can be used both as a service brake for dynamic applications, and as a holding brake with an emergency stop function for static applications. Thanks to its modular system, the COMBISTOP can be easily assembled according to individual requirements in terms of braking torque and varied options. Even project solutions for implementing specific requirements that go beyond the standard can be achieved thanks to our in-house development and production.

The standard brake has a torque range of 2.5 Nm to 2,000 Nm.

Options

The COMBISTOP 38 can optionally be equipped with a hand release so that it can be opened manually.

The benefits of this are most obvious in de-energised situations when the application still needs to be moved. Even if a rotor is worn, the brake can be released with the hand release

The COMBISTOP 38 can be equipped with a microswitch to monitor performance or wear and tear.

Using a COMBISTOP 38 with a microswitch makes particular sense for brake motors on hoisting gear and load lifting gear that are operated with frequency inverters.

The COMBISTOP 38 can optionally be equipped with a flange or alternatively, for the smaller sizes, with a friction disc.

If the motor endshield lacks the appropriate properties, such as material quality or evenness, a flange or friction disc provides an optimal counter-friction surface.

The COMBISTOP 38 can optionally be equipped with a dust protection ring to increase the IP protection class for dusty and damp environments, or to provide protection against accidental contact.

IP54 protection can be achieved under the motor hood by installing a dust protection ring – and up to IP44 at the open end of the motor.

If the continuous shaft on the COMBISTOP 38 needs to be sealed against the external environment, it can be equipped with a shaft sealing ring.

Where there is no shaft, the COMBISTOP 38 can be sealed with a sealing plug.

The COMBISTOP 38 is available in a CCV design for use in particularly harsh and cold environments. Temperatures as low as -40°C are therefore no problem for the brake.

If you wish to attach a rotary encoder, fan or sensor to the back of the brake, the COMBISTOP 38 can be produced with rear-side threaded holes in the required size and corresponding bore hole pattern.

If the braking torque needs to be modified for the application, the torque can be increased or reduced according to the customer’s specifications during the internal production process.

For applications with specific requirements in terms of installation depth, the housing and overall length of the brake can be reduced. Start-up is particularly easy because KEB adjusts the brake so it is ready for use.

If the application requires a modified voltage, a customised coil with the corresponding voltage can be realised in the internal production process.

If the assembly process of the brake has to be simplified, our products can be equipped with ready-to-connect cables with plugs, contacts or even wire end ferrules.

A factory certificate 2.1 according to DIN EN 10204 that the delivered products comply with the agreements at the time of order can be provided at the customer's request. This certificate is issued based on non-specific testing. Also, an acceptance test certificate 3.1 according to DIN EN 10204 can be issued at the customer's request. In this case, the confirmation is given with the results of specific tests, such as the torque test.
