Magnetic Brake (ZX single-output shaft spigot support ultra-thin magnetic powder brake) Basic characteristics of the magnetic particle clutch, magnetic particle brake and selectionA linear relationship of the magnetizing current and the output torqueMagnetic particle clutch, magnetic brake is based on electromagnetic principles using magnetic output torque. Its output torque and exciting current basic linear relationship, simply changing the size of the excitation current can easily control the output torque. Under normal circumstances, in 5-100% of the rated torque range, exciting current to its output torque proportional relationship.Slip torqueWhen the magnetizing current remains unchanged, the output torque from the differential speed between the drive member and the driven member (slip speed) static torque and dynamic torque undifferentiated. Magnetic particle clutch, magnetic particle brake very stable output constant torque. This feature is applied to the tension control, customers only need to adjust the excitation current size, can be simple, effective, accurate to control the tension of the coil material purposes.

Control power, fast responseMagnetic powder clutch, magnetic particle brake excitation current is small, but it can output a large torque, which can be easily composed of the automatic control system. In addition, When exciting current change, the corresponding magnetic field strength synchronous response magnetic clutch, magnetic powder brake and therefore have the amazing response speed.ApplicationsDue to the magnetic particle clutch, magnetic brake with unmatched characteristics above, is now widely used in packaging, printing, paper, textile, printing and dyeing, rubber, wire, cable, metallurgy and other take-up in the processing industry unwinding resumption tension control. In addition, the magnetic powder clutch can also be used for speed control, overload protection and buffer start. Powder brake is often used to the dynamometer loading of transmission machinery and brake.Selection ConsiderationsMagnetic powder clutch, magnetic particle brake selection is generally required to convey the maximum torque based on selected, taking into account the actual power should be less than the magnetic powder clutch slip, magnetic particle brakes allow slip power. The formula is as follows:P = 2π/60 · M · n = F · V where: P - the actual slip power (W)                                 M - torque (N · m)                                 n - slip speed (rpm)                                F - the actual tension (N)                                 V - linear velocity (m / s)In the case of non-transmission mechanism, the maximum required tension of the winding material and the product of the maximum winding radius should be less than the rated torque of the the selected magnetic clutch or magnetic brake.Magnetic powder clutch, magnetic particle brake cooling conditions must slip power is a certain value, the actual torque and speed can compensate for each other, that is, the slip speed increases (must not exceed the maximum speed), the allowable torque will correspondingly reduced.The cases: ZKB100HBN powder brake rated torque M = 100 N · m, slip differential power P = 1400WThe rated torque, the long-term operation of the rated speed: n = 60P/2πM = 134 rpmIf the actual slip speed up to 1000 rpm, then dropped to the allowable torque: M = 60P/2πn = 13 N · m
