Reliable braking systems are not just beneficial; they’re essential. One of the most critical types of brakes in modern mechanical engineering is the motor-mounted brakes, which ensures safe, controlled, and efficient operation of industrial equipment.
As a trusted South African distributor of Dellner Bubenzer brake systems, Huebner Speed Monitoring provides high-performance braking solutions tailored for both static and dynamic applications across sectors such as mining, manufacturing, energy, construction, and logistics.
This article explores the significance of motor-mounted brakes, their functionality, applications, and why choosing high-quality systems like Dellner Bubenzer is vital for businesses prioritising safety, uptime, and productivity.
What Are Motor-Mounted Brakes?
Motor-mounted brakes are braking systems installed directly onto the motor shaft or housing. These brakes are typically electromagnetic or spring-applied and function by halting the motor’s rotation when power is cut off or when braking is required during operation.
They are commonly used in:
- Hoists and cranes
- Conveyors
- Elevators
- Winches and winders
- Automated manufacturing equipment
- Pumps and fans
- Material handling systems
How Do Motor-Mounted Brakes Work?
The most common types of motor-mounted brakes include:
Spring-Applied Brakes (Fail-Safe Brakes)
These brakes engage automatically when power is lost, using spring force to apply the brake and halt movement. They are released only when electrical power energises a coil, compressing the spring.
Advantages:
- Fail-safe operation during power loss
- Ideal for emergency stopping
- High holding torque
Electromagnetic Brakes
Electromagnetic brakes use a magnetic field generated by an electric current to engage or release the brake pad. These systems are more suitable for dynamic braking applications and precise control.
Advantages:
- Smooth, quiet operation
- Excellent for frequent stop/start cycles
- Fast response times
Why Motor-Mounted Brakes Are Crucial in Industrial Applications
- Enhanced Safety: Safety is paramount in industrial settings. Motor-mounted brakes provide immediate response in emergencies, preventing accidents due to uncontrolled machinery movement. In applications like cranes, elevators, and lifts, these brakes serve as a critical safety component to protect workers and equipment.
- Precision and Control: Industrial processes often require precise positioning. Motor-mounted brakes allow for exact stopping and holding positions, essential in automated production lines, CNC machines, and robotics.
- Space-Saving Design: Because motor-mounted brakes are integrated with the motor, they require less installation space compared to external braking systems. This is particularly beneficial in compact machinery where space constraints are a concern.
- Energy Efficiency: By reducing the need for continuous motor operation and controlling the stopping mechanism more efficiently, motor-mounted brakes help save energy and reduce wear and tear on the entire system.
- Reduced Downtime: When quality motor-mounted brakes, such as those from Dellner Bubenzer, are used, they significantly improve machine reliability. Fewer breakdowns mean less downtime and more productivity.

FAQs About Motor-Mounted Brakes
What industries use motor-mounted brakes?
They are widely used in mining, manufacturing, material handling, energy, construction, and logistics sectors.
What is the difference between motor-mounted brakes and external brakes?
Motor-mounted brakes are directly attached to the motor, saving space and providing immediate stopping action, while external brakes are mounted on shafts or elsewhere in the system.
Are motor-mounted brakes suitable for both horizontal and vertical applications?
Yes. Dellner Bubenzer designs brakes that are suitable for a range of orientations and load types.
How often should motor-mounted brakes be serviced?
Regular maintenance should be performed every 6 to 12 months, depending on usage and environment. Huebner Speed Monitoring provides scheduled servicing options.
Can I retrofit motor-mounted brakes onto existing equipment?
Yes. Huebner Speed Monitoring offers solutions tailored to new installations and retrofitting needs.
Do motor-mounted brakes work during power outages?
Fail-safe spring-applied brakes automatically engage when power is lost, providing critical protection during outages.
