You can change the braking force by varying the voltage even while powered. 【Features】 ○ The material of the disc is not specified, but the surface roughness should be around 3S to 6S. If the disc surface is plated, depending on the type of plating, there may be cases where the displayed braking force does not appear due to a decrease in the coefficient of friction. ○ The time to adjust is when the braking force has decreased. Please adjust by turning the yoke clockwise. ○ There are special shapes that ensure a gap between the pads and the disc when released. ○ It is suitable for discs made of materials other than iron, or for infrequent jobs or clamping. For frequent use, please consider the non-adjustable GDN type. For more details, please contact us or download the catalog.

• brake

It is suitable for safety applications during power outages or when the holding time is long. 【Features】 ○ Compact and lightweight, requiring minimal installation space. ○ When the pad wears out, the coil will no longer attract the armature. At this time, adjust by turning the yoke. ○ At the time of shipment, the gap is set to zero using the manual release nut. Please loosen the manual release nut after installation is complete. ○ The initial gap between the disc and the pad should be set to approximately 0.1 mm. If it is too large, the lifespan until the next adjustment will be shortened. ● For more details, please contact us or refer to the catalog.

• brake

This is a non-excited operation brake that is released by electromagnetic force and braked by a spring. 【Features】 ○ Due to its large stroke, it has a long lifespan until the next adjustment and is used for heavy-duty work. ○ During release, the brake pads are completely separated from the braking body, so there is no influence from idle torque and no unnecessary pad wear. ○ Installation and adjustment are easy. ○ The simple structure ensures there are no failures. ○ Various mounting options are available, including single pressing, opposing, and side-by-side configurations. ○ The brake surface can be mounted on any location of the rotating body, including the side, outer circumference, and end face, making it easy to install on existing machinery. ○ Brake adjustment is performed using mounting long holes. ○ For use as a holding device, high-holding-force cork types are also available. *For more details, please contact us or download the catalog.

• brake

It is used when the operation of the electromagnetic clutch or brake is incomplete or slow due to the influence of residual magnetism. It can be reliably activated by the action of reverse current. 【Features】 ○ When the DC voltage from the power supply is cut off, a slight DC reverse current is applied to the electromagnetic clutch and brake by the capacitor in the degausser, eliminating the residual magnetism of the electromagnetic clutch, brake, and disk. ○ The optimal reverse current application time varies depending on the internal resistance and mechanism of the electromagnetic clutch and brake, but it is approximately 0.1 to 0.5 seconds. The degausser allows for presetting the optimal value using a variable resistor knob. After that, no adjustment of the variable resistor knob is necessary unless the capacitor deteriorates. ○ The degausser was developed for our electromagnetic clamp model MDB and electromagnetic disk brake model GDN, but it can also be effectively used for other manufacturers' electromagnetic clutches, brakes, and electromagnetic products if the internal resistance value is in the range of 10Ω to 100Ω. *For more details, please contact us or download the catalog.
