Electromagnetic multiple-disc clutch Type 521

Electromagnetic multiple-disc clutch - Type 521 Characteristics and features • suitable for torque transmission with increasing differential speed between the drive elements • high torque transfer despite compact dimensions • designs up to 2100 Nm possible • high switching frequency due to optimized heat dissipation • low maintenance due to slip-ring-free power supply and lifetime-lubricated bearings • negligible wear due to special friction lining • oil running or dry running • suitable for applications in harsh environments • reduced shift speeds due to adapted control Mönninghoff power...

Electromagnetic multiple-disc clutch - Type 521 Match code Mönninghoff multiple-disc clutches are indicated by the following match code: 521 . A . B . C A clutch size B operating mode C length of drive ring Other individual characteristics: • voltage • bore size with keyway According to these characteristics, we design individual solutions concerning transmitted torque, engaging behavior or rotation speed. Our engineers can assist with finding an application-specific clutch at any time. Together, we can develop individual and innovative solutions for extreme operating conditions. Ordering...

Electromagnetic multiple-disc clutch - Type 521 Clutch size The selection of the correct size of a Mönninghoff electromagnetic multiple-disc clutch is determined by the requiered torque as well as the shift work. • ccording to the required torque A MS ≥ • According to the shift work Eh ≤ Qh The clutch must transfer load and acceleration torque (ML; Mb). The required safety is obtained by using a corresponding safety factor (K). If the load and acceleration torque cannot be determined, the required torque can be derived from the driving power, taking the required safety into cosideration. ML...

Electromagnetic multiple-disc clutch - Type 521 Determination of shift work The energy that is lost in the clutch depends on the shift curve and the shift frequency. The correction factors for the permissible shift work per hour Qh can be derived from the tables and graphs. Course of a shift cycle tg = time during which the clutch is closed tz = total cycle time ∆ω = differential angular velocity Correction factor k1 as a function of the shift frequency per hour I valid for 521.32 - 521.33 II valid for 521.24 - 521.28 III valid for 521.21 - 521.22 IV valid for 521.16 Correction factor k2 as...

Electromagnetic multiple-disc clutch - Type 521 Switching Electromagnetic clutches are inductances. Engagement and disengagement are subject to the laws of induction, i. e. the induction current increases according to an e-function. Shift diagram: normal shifting • t1 and t2 can be electrically influenced by taking appropriate measures • it is advisable to use direct current for shifting • when determining the size, the engage time is considered to be approximately 30% of the total acceleration time, which normally results in additional safety Technical data Size normal excitation for oil...

Electromagnetic multiple-disc clutch - Type 521 Operating mode Mönninghoff electromagnet multiple-disc clutches are avaible in two operating modes • Type 521._.1._ for dry running • Type 521._.2._ for oil running To reduce the engage time, fast excitation can be achieved by applying up to three times the rated voltage. When oil is used and particularly if the oil is cooled internally, the rise time can be affected considerably and may double or triple (observe oil instructions). Use oil with a viscosity up to 25 x 10-6 m2∙s-1 by 50 °C (3°E / 50 °C). Voltage • standard voltage is 24 Vdc...
