磁粉制動器工作原理


 磁粉離合器、磁粉制動器是根據電磁原理并利用磁粉來傳達轉矩的,其傳達之轉矩與激磁電流基本成線性關系。因此,只要改變激磁電流之大小,便可輕易地控制轉矩之大小。正常情況下,在5%至100%的額定轉矩范圍內,激磁電流與其傳達之轉矩成正比例線性關系.

 
     The brake magnetic powder clutch, magnetic powder is based on the electromagnetic principle and the use of magnetic powder to convey torque, the transmission torque and excitation current is basically linear relation. Therefore, as long as the change the size of the exciting current, you can easily control the torque of the size. Under normal circumstances, in the range of 5% to 100% of the rated torque, torque and excitation current of communication is proportional to the linear relationship.
 
     當激磁電流保持不變時,其傳達之轉矩不受傳動件與從動件之間差速(滑差轉速)之影響,即靜力矩與動力矩無差別。因此可以穩定地傳達恒定之轉矩。此特性若運用于張力控制,則用戶只需調節激磁電流之大小,便能準確控制并傳達所需轉矩,從而簡便、有效地達到控制卷料張力的目的.
 
     When the excitation current is kept constant, the communication is not affected by the torque transmission piece and follower differential (slip speed) influence, namely static torque and dynamic torque difference. So it can be stable to convey a constant torque. This characteristic is used if the tension control, the user only needs to adjust the size of the exciting current, it can accurately control and deliver the required torque, thereby conveniently and effectively to control the roll tension.
