Magnetic Powder Brake For Cross Cutting Machines And Bag Making Machines

Basic product information

Product Overview

Magnetic powder is based on electromagnetic principles and utilizes magnetic powder to transmit torque. It has the characteristic of a linear relationship between excitation current and transmitted torque. It can transmit a certain amount of torque regardless of slip, with advantages such as fast response speed, simple structure, no pollution, no noise, no impact vibration, and energy conservation. It is a versatile and high-performance automatic control component. It has been widely used in the unwinding and rewinding tension control of papermaking, printing, plastics, rubber, textiles, printing and dyeing, wires and cables, tablet presses, and other related coiling and processing industries. Magnetic powder brakes are often used for power testing, loading, and braking of transmission machinery

operational principle

Magnetic powder brake is composed of a combined transmission unit (input shaft) and a driven unit (output shaft). The space between two groups of units is filled with granular magnetic powder (with a volume of approximately 40 microns). When the magnetic coil is non-conductive, torque will not be transmitted from the transmission shaft to the driven shaft. However, if the coil is electromagnetically energized, the magnetic force will attract the magnetic powder and cause hardening, which will transmit torque between continuous sliding

Product features

1. It can achieve continuous sliding operation

2. Stable torque can be obtained

3. No beeping sound. The phenomenon of sliding on the action surface may occur in the friction mode, but it does not occur here and does not emit a connecting sound, so the operation is quite quiet

4. The heat capacity is very large. Thanks to the use of heat-resistant magnetic powder and the ideal cooling method, even in extremely harsh continuous sliding operations, it can be used with peace of mind

5. It can be driven to a smooth and continuous state. Due to the almost identical precision friction coefficient and dynamic friction coefficient, there will be no oscillation when fully connected, and the speed can be increased or decreased according to the load

Product Usage

1. Buffered start and stop: Utilize the smoothness and fixed rotation characteristics of the connection to achieve buffered start and stop

2. For continuous sliding and tension control

3. For torque limiters

4. For high-speed response

5. For power absorption

6. Stop using positioning

7. For simulating loads
