Electromagnetic powder clutch/brake
RoHS compliant! No sound when operating, large thermal capacity, and smooth continuous slip powder brake/clutch! It is also micro-sized.
Our company produces various types of electromagnetic clutches and brakes, and we have accumulated a wealth of know-how through extensive applications and achievements, allowing us to meet our customers' needs. Leveraging numerous features, we have become essential for tension control in actuators used for winding and unwinding long materials such as paper, thread, electric wires, various sheets, and tapes. Additionally, they are suitable for applications such as soft start, power absorption, or overload safety devices (torque limiters).

basic information
- Easy control over a wide range: The transmitted torque changes continuously in response to changes in excitation current, allowing for easy control of the transmitted torque over a wide range. - Continuous slip operation is possible: By using powder, the operating surface can continuously slip, and stable transmitted torque can always be obtained regardless of the slip rotation speed. - Stable torque can be obtained: Due to the shape of the operating surface and maze structure, the powder always moves normally, allowing for stable torque to be reproduced even with repeated ON/OFF of the current. - No squeaking noise: Since stick-slip on the operating surface, commonly seen in friction plate systems, does not occur here, quiet operation is possible. - Large thermal capacity: Using heat-resistant powder and an ideal cooling structure, it can be used even in harsh continuous slip operations. - Smooth connection and drive are possible: Since the static friction coefficient and dynamic friction coefficient are almost equal, there is no shock during complete connection, and acceleration and deceleration speeds can be obtained according to the load. *If you have any inquiries or requests regarding the product, please feel free to contact us.
