How Braking Units Enhance Safety for Electromechanical Parts and Components

In modern industrial settings where high-precision automation equipment drives processes, the presence of reliable braking units is indispensable. These components are engineered to effectively control deceleration and halt motion for moving machinery and electromechanical systems, protecting both hardware and operators alike. After reading this blog, you will have a stronger understanding of how braking units contribute to safety, the functionality of some of their many variations, and how to ensure you pick dependable options.

The Role of Braking Units in Electromechanical Systems

Braking units are safety-critical devices integrated into various electromechanical systems, being especially common in automation equipment where rapid, repetitive, or forceful movement must be precisely regulated. These components serve an array of devices, including electric motors, servo drives, and motion control assemblies. In all of these cases, braking units serve to absorb and dissipate excess energy, ensuring that mechanical motion is stopped without abrupt shocks or hazardous recoils.

Braking units are typically constructed with components that allow them to manage energy safely and reliably, often including circuitry to regulate performance and additional mechanisms to prevent overheating. To withstand the demands of industrial settings, they are commonly housed in robust enclosures designed to resist dust, vibration, and temperature fluctuations. As automation continues to advance, many braking units are also being integrated with digital control systems for more responsive operation.

Notable Types

Dynamic Braking Units

Dynamic braking units convert excess kinetic energy from moving equipment into heat energy using resistors. The converted heat is then dissipated through a resistive grid or external heatsink. This process allows electric motors to stop more quickly and safely than through coasting alone, and they are particularly effective in applications involving high-speed electric motors like conveyor systems, cranes, and elevator drives. Some subtypes include:

Regenerative Dynamic Brakes: These systems not only dissipate energy as heat, but also recover a portion of it to be fed back into the power system. This improves energy efficiency while preserving braking performance.

Non-Regenerative Brakes: Solely converting excess energy into heat, these breaks are compact and straightforward for simpler setups.

Spring-Applied Braking Units

Spring-applied braking units are engineered to engage automatically when power is lost, providing a simple fail-safe. These brakes use spring tension to apply braking force, while electromagnetic force releases the brake during operation. This configuration makes them common in vertical load applications where sudden free-fall must be prevented like elevators, as well as robotic arms and other automation equipment requiring safe shutdown in the event of an emergency.

Electromagnetic Braking Units

Electromagnetic brakes generate magnetic force to create friction between rotating and stationary surfaces, producing a smooth and fast stop. These brakes respond quickly to control inputs without excessive mechanical wear, making them essential for operations demanding high accuracy like machinery, robotics, and semiconductor production. Two primary types of electromagnetic brakes are:

Power-Off Electromagnetic Brakes: These variants automatically engage when electrical power is cut, making them useful for emergency stop applications.

Power-On Brakes: These brakes activate only when electrical power is applied, leading to their use in dynamic applications where controlled stopping or holding is required during continuous operation.

Eddy Current Braking Units

Eddy current brakes generate a magnetic field through a conductive, non-magnetic rotating disk. The interaction of the field with the metal creates resistance, slowing the rotation without any contact. This offers a long service life with minimal maintenance, making eddy current brakes a preferred option for high-speed train systems, test benches, and centrifugal machines. Additionally, it is worth mentioning that these variants are sometimes used in synergy with other braking units for maximum control.

Considerations for Purchasing Braking Units

When choosing braking units, one should evaluate not only the appropriate type for the functional requirements of an application, but also their reliability and origin. Braking mechanisms should be sourced from reputable manufacturers known for delivering consistent performance and engineering excellence, such as those behind Yaskawa automation solutions and Fanuc automation technology. Dependable companies like these offer a range of electromechanical braking units designed to meet stringent industry standards, which is imperative for compatibility, operational safety, and long-term system efficiency across a wide range of automation environments.
