Electromagnetic clutches and brakes, couple, release, brake and hold machinery in place using electromagnetic force generated by passing a current through a coil. The products are electromagnetically actuated or spring actuated. The electromagnetic actuated range further divides into several major categories: electromagnetic-actuated clutches and brakes, spring-actuated brakes, electromagnetic tooth clutches, brake motors, and electromagnetic clutch and brake power supplies. With compact and durable designs the electromagnetic clutches and brakes can be used in a large variety of applications. Ideal for use with large and small transmission, the program also incorporates torque limiting flexible shaft couplings, overload protection, industrial clutches through to micro brakes & clutches.
Safety brakes in machinery serve a similar purpose to safety brakes in vehicles – they are mechanisms designed to stop or hold machinery in place during emergencies, power loss, or maintenance activities. These brakes are an essential component of industrial equipment and machinery to ensure the safety of operators, prevent damage to the machinery, and comply with workplace safety regulations.
Here's how safety brakes are commonly used in machinery:
Emergency Stop Functionality: Safety brakes are often integrated with an emergency stop (E-stop) system. When the E-stop button is pressed or an emergency situation is detected, the safety brakes engage immediately to halt the movement of the machinery. This rapid and reliable braking action helps prevent accidents and injuries.
Power Loss Prevention: In cases of power loss or sudden loss of control signal, safety brakes are designed to automatically engage and stop the movement of the machinery. This prevents the machinery from continuing to operate uncontrollably, reducing the risk of damage to the equipment and surrounding infrastructure.
Maintenance and Servicing: Safety brakes are used to secure machinery in a stationary position when maintenance or servicing is required. This ensures that the machinery cannot start unexpectedly while maintenance personnel are working on it, preventing potential accidents.
Load Holding: In applications where machinery carries heavy loads, safety brakes can be used to hold the load in place even when the machinery is not actively powered. This is important to prevent accidental movement and potential hazards.
Overload Protection: Safety brakes can also function as overload protection devices. If the machinery is subjected to forces beyond its design limits, the safety brake engages to prevent damage to the machinery or the load it is handling.
Redundant Systems: Critical machinery often employs redundant safety brake systems to provide extra layers of protection. If one system fails, the backup system can take over and stop the machinery.
Safety brakes in machinery can operate using various mechanisms, including mechanical, hydraulic, pneumatic, or electromagnetic systems. The choice of safety brake system depends on factors such as the type of machinery, the loads involved, the required response time, and the applicable safety standards.
