Ogura Industrial Corp. has created a new animation showing how permanent magnet brakes work. The animation shows an exploded view of the component parts and how they interact with each other. In permanent magnet brakes, holding force is created by permanent magnets and released by energizing the magnetic field. Permanent magnet brakes are higher torque […]
Brakes + Clutches
When is internal braking for stopping insufficient — and a clutch or brake necessary?
For a given motion profile, when are other options for stopping insufficient — and a clutch or brake necessary? Good question. At the core of most motion axes are electric motors. Stopping loads on their axes can be done with the electric motor itself — called internal braking in certain contexts — or with an […]
Miki Pulley BXR-LE electric brakes for direct drive servo motors
Miki Pulley’s BXR-LE electric spring applied brakes are suitable for small and precise servo motor configurations. Their unique compact and lightweight design optimizes servo drive performance and efficiency. With accompanying voltage controller, the brake’s power consumption is stepped down to 7VDC after a split second of 24VDC for brake actuation. When compared to most other […]
Safety brakes and intelligent monitoring from mayr for brake technology 4.0
Safety brakes by mayr power transmission are equipped for the challenges of the Industry 4.0. The coordinated system guarantees the highest level of operational and functional safety … … and increases the productivity of machines and systems through predictive error detection and maintenance. Brake technology 4.0 stands for intelligent monitoring modules; modules such as the […]
Miniature brakes, clutches, and torque limiters from Mach III for shaft sizes to a half-inch
Brakes, clutches and torque limiters are now available from Mach III for shaft sizes of half-inch and smaller. The ten new products include: • A spring-engaged brake for power off applications • An air-engaged brake for stopping and holding applications • Five air-engaged clutch configurations for connect and disconnect applications • Three mechanical torque limiters […]
How do cam clutches work, and what are other overrunning clutch options?
Mechanical overrunning clutches, sometimes called one-way or backstop clutches depending on the context, transmit torque in one drive direction but let the output axis continue to turn (freewheel) when the driving motor slows or stops. Such clutch function is useful in large and small designs for material handling, packaging, conveying, medical, turbine auxiliary drives, and […]
Clutch/brakes allow precise positioning with virtually no maintenance or adjustment
Posidyne clutch brakes from Force Control Industries feature oil shear technology for rapid and precise stopping, starting, speed change and positioning, all without adjustment or maintenance. Ideal for applications with frequent start/stop cycles, such as indexing conveyors, rotary tables, batch feeders, rotary coal samplers, cutoff machines, and more, these unique motion control devices allow higher […]
New ultra-thin power-off brake from SEPAC
SEPAC’s new line of extremely thin power-off brakes, the UTSEB Series (Ultra Thin Spring-Engaged Brakes), is offered in five standard frame sizes from 1.14 to 2.68 in. in diameter and lengths from 0.47 to 0.67 in. The ultra-thin design provides a short package size when the brake is mounted to the rear of a motor; […]
New zero-backlash, spring-engaged brake family
Nexen Group Inc. has announced the Zero-Backlash Spring Engaged (ZSE) brake family. The pneumatically-released ZSE offers high torque, high speed, and zero backlash ideal for holding applications. Unlike brakes using leaf springs to transmit torque, the ZSE is zero-backlash up to 100% of its rated holding torque. Nexen has released four different sizes (450, 600, […]
Brakes and clutches: Top trends in IoT — and uses on ac-motor conveyors and servodesigns
Clutches and brakes work in motion systems to stop or hold or index axes — but must do so to application specifications. No wonder then that the trend in this technology is away strictly stock parts. According to Lesli Riehemann, president at Mach III Clutch Inc., customized brakes and clutches are now 75 to 80% […]
