Options
Spring-set Brakes: Add a spring applied (spring-set) brake to your gearmotor. KEB COMBISTOP Spring Set brakes provide failsafe braking functionality with boosted coils for higher torque and a robust design for tough industrial applications.
KEB brakes provide power-off brake engagement. The brakes used are KEB’s Type 38 brake which includes common options like a manual hand release and micro switch. A quiet brake is available for theatre and stage applications.
Feedback devices
KEB motors can be configured with feedback devices. Common formats include: TTL, HTL, resolver, BiSS, and Hiperface.
Customized outputs
KEB can provide gearmotors with custom flanges or shafts to facilitate mounting to the machine. It is also possible to provide an output flange or shaft on both output sides.
Food Grade Lubricants
For use in food production, KEB gearmotors can be provided with food grade lubricants and greases.
Extra Environmental Protection
For use in washdown or corrosive environments, the gearmotors can be supplied with extra paint protection and seals.
Helical Gear Applications
Helical gears are renowned for transmitting motion and power between non-parallel shafts. By applying helical gear technology, industries benefit from wear-free operation and a long service life, ensuring reliability and performance.

Best Applications for Helical Bevel Type Gearmotors
Typical applications for our helical bevel gearmotors include industrial door lifts, theatre hoists, and cable drum driving. Our gearmotors can be mounted by either foot or flange mount, and we can machine custom flanges to fit your application needs.
The bevel gearing provides a right-angle output. We offer hollow shaft outputs as well as a variety of custom-machined solid output shafts.
The popularity of KEB's helical bevel gearmotors stems from their high efficiency, versatility, and cost-effectiveness. They are ideal for applications needing continuous high-output torque, which sets the stage for understanding their superior efficiency compared to worm gearmotors.
Considerations
Sizes Available
KEB’s helical bevel gearmotors range from .25hp to 50hp, and we offer many complementing options/add-ons for whatever your application may require.
Upfront Cost vs Lifetime Cost
Although the initial cost may be higher for the helical bevel gearmotors, the long-term operation costs will be higher if you select a worm gearmotor. You will pay much higher energy costs since the worm gearmotor is less efficient than the KEB helical bevel gearmotor.
Efficiency of Helical Bevel Gearmotors vs. Worm Gearing
People often think that worm gearmotors are the better option because they can achieve the desired output speed and torque for an application at a lower price. However, a drawback to worm gearmotors is the less efficient operation when compared to helical bevel gearmotors. Watch 5 Main Gear Types & Their Characteristics
Worm gear efficiency is often around 80%, but KEB's helical bevel gearmotors are 90+ % efficient. The higher efficiency comes with other benefits, such as less heating and less audible noise when compared to worm gearing. Additionally, you can use a smaller motor for a given output torque.
IE3 Efficiency Standards
Rising energy costs have been a big topic recently, and they will continue. Governments have long understood that electric motors are a large consumer of electrical energy globally and have been working to adopt legislation to increase motor efficiency.
KEB understands the changing landscape and has made electromagnetic changes to the stator windings to meet the higher IE efficiency requirements in Europe and North America.

Brake Solutions for Gearmotors
We can add our spring-applied brake solution to the non-drive end of the motor for applications where dynamic braking is needed or for applications where a secondary holding brake is necessary. We can even mount a load brake onto the output of a helical bevel gear motor for hoist and theatre applications.
We offer both incremental and absolute encoders for applications requiring strict positioning, and we offer an IP65-rated gearmotor solution for washdown applications.
