Initial Torque
To ensure a strong attractive force between armature and magnet, the friction surfaces must be clean and burnished. Burnishing is a process to runs the unit to breaking the friction surfaces, thereby maximizing friction and torque. In dynamic applications, the friction surfaces slip upon each engagement (which continues the burnishing effect), keeping them free from corrosion and debris. This slippage maintains correct alignment and full contact of the friction surfaces. Rotating speed for burnishing is ideally set at 30 rpm per minute.
While in installation, the axial clearance of an axis shall be less than 0.05mm; while in installation of the core, the main part shall not hit by a hammer.
Please set up consistent voltage for the brake release voltage and rated voltage; however, there might be changes made during installation, so, please align the voltage in practices again after in completion of installation.
Please use flat and smooth type of power such as pure DC power or full-wave rectifier; if for the sake of using lift and other machines safely, please use mandatory reverse excitation circuit. When the power supply continues, the positive electrode is in red while the negative one is in black; please make it correctly.
Avoid attaching oil stains or water to the friction surface, so it is best used in the dry state.
Because there is strong force of magnet inside of the product, so please do not make the iron powder or mechanical powder approach the product. For the use in an environment with dust or iron powder, please use dustproof cover.
After assembly, it may not be in a fixed level of torque temporarily, so, upon it is assembled, operate it for 30~50 times under the rotation speed as 30~60rpm while power off.
The permanent magnet brakes shall be used at 0~40℃; it shall not used in an extremity of heat or humidity.
