The space between the two groups of unit is filled with some granular magnetic powder (volume about 40 microns). When solenoids don’t conduct electricity, torque can’t work between drive shaft and driven shaft. But when the coils are power on by electromagnetic, it will attract magnetic powder and cause sclerosis phenomenon by magnetic force. Then torque will be transmitted by sliding.
Magnetic powder clutch is a kind of the superior performance of automatic control components. We take magnetic powder as the working medium and magnetizing current as the control measure to achieve braking control and torque transmission. Its output torque has fine linear relation with magnetizing, but has nothing to do with speed and slid. it is characterized by rapid response speed and *** structure. It is widely used in tension automatic control systems of wire, cable, packaging, printing, *** and *** processing, textiles, rubber, leather, metal foil tape processing and other relevant coiling device. Magnetic powder clutch is also used in the buffer starting, overload protection, speed switch, etc.
(1) high-precision torque control The torque can achieve high precision control and wide control range through conveying torque and exciting current into the right proportion.
(2) excellent durability and long service life Magnetic powder clutch has long service life by using heat resistance, abrasion resistance, resistance to oxidation and corrosion resistance super ultra alloy powder.
(3) stable constant torque characteristics Magnetic powder has magnetosphere characteristics, and the adhesion between particles is quite. Sliding torque is very stable, and the relative rotation several no relationship can abiding constant torque.
(4) continuous sliding operation use Magnetic powder clutch has good heat dissipation and uniform cooling structure of thermal deformation. Then high heat resistance of magnetic powder allows links and braking power and sliding high power, can smooth sliding operation, and won't cause vibrations. (5) link smooth, non-impact There is no impact when it links. It can start and stop smoothly non-impact. And resistance torque is tiny and won't cause useless calorific value.
(6) suitable for high frequency operation It is suitable for high frequency operation use with quick response and special quick cooling structure,
(7) lightweight, maintenance-free, long service life It is lightweight using concise type of high-temperature coil and special grease bearings. And imposing wear-resisting attrition easily armature special treatment can prolong service life.
Edit features of the product 1. Magnetic powder clutch and brake is a kind of the superior performance automatic control components
2. It is with high linear and high-precision torque control. 3. It uses high temperature resistant coil super alloy powder and can prolong service life. It is smooth in connection and there is non-impact magnetic particle clutch.
4. The product of high precision, the careful treatment, excellent linearity, superior performance is made by CNC precision manufacturing.
5. Magnetic powder is high purity without black carbon powder and stable performance with long service life .
6. The aluminum-alloy structure is with excellent thermal performance, good retreat magnetic and fast response.
7. At startup, operation and braking condition, it works smoothly without vibration, shock and noise.
8. As the torque is proportional to and exciting current in the provision of torque range, we can take it as linear regulating elements.
9. Output torque is constant, because torque size just depends on the size of the current excitation and has nothing to do with sliding speed.
10. Parting or gathering is frequent with fast response, higher frequencies and every minute can achieve 40 to 60 times. It can be widely applied in rapid working status and high frequency occasion.
11. With high power magnification, it is easy to achieve automatic control by using small exciting current to control large transmission power.
