Features of BXL Models

These are dry, spring-actuated brakes that are compact and dedicated for braking. They use a friction material with high wear resistance, stand up to long hours of use, have small torque fluctuations, and brake loads instantly even under abnormal circumstances.The effect of the rotor spring located on the outer periphery of the rotor reduces unpleasant high-frequency friction noise that occurs during braking. Braking is quiet.

Option no.: 12
In addition to the manual release tap of the standard product, we also offer an optional manual release lever. See the dimensions table below for the dimensions of brakes with release levers. Other specifications are the same as the standard specifications.

Quiet Mechanism (Silencing Spring) *Made to Order

Option no.: S1
There is a extremely small structural backlash (see figure on the right) between the rotor and the rotor hub. In applications that are prone to microvibrations of the drive shaft such as single-phase motors, this backlash may produce rattling (banging). The silencing spring for the rotor hub reduces this rattling..

Quiet Mechanism (Pull-in Noise Reduction Mechanism) *Made to Order

Option no.: S2
When the brake is energized, a magnetic circuit is formed, and the armature is pulled to the stator by that magnetic force. At that time, the armature touches the magnetic pole of the stator and a noise is produced. This sound (pull-in noise) is reduced by putting shock absorbing material in the stator's magnetic pole part..
In option S2, in addition to the pull-in noise reduction mechanism, the silencing spring (option S1) is also supplemented..
