A permanent magnet electromagnetic brake that achieves high-speed response through backlash-free operation.

The 【CPB/PB1/PB2 series】 generates braking force through the magnetic force of permanent magnets, unlike spring-type brakes. The armature is driven by a leaf spring mechanism, resulting in no backlash in the rotational direction and no drag torque. 【Features】 1. High-speed response: The magnetic force of the permanent magnet attracts the armature towards the magnet side, providing quick responsiveness. 2. No backlash: The armature is driven by a leaf spring mechanism, ensuring there is no backlash when transmitting torque. 3. Quiet operation: The armature is directly connected to the leaf spring, eliminating noise during rotation and avoiding drag torque. 4. Compact: By using high-quality permanent magnets, it achieves higher torque even with the same size. Torque range: 0.4Nm to 140Nm Smallest outer dimensions: 19.5×39 The PB1/PB2 series comes with a hub. ■ We have staff who can speak Japanese. Please feel free to contact us with any inquiries or requests. ■

Long lifespan / precise torque adjustment / energy-saving / accurate torque repeatability / unlimited mounting direction.

The Sentai Company Original Permanent Magnet Torque Controller [CHT Series] has two characteristics: "high reliability torque controller performance" and "minimal wear." Unlike friction-type clutches and brakes, the torque in the CHT series is transmitted by magnetic force. Permanent magnets are fixed between two bases. The shaft is secured to a hysteresis plate. Through the permanent magnets in the base, the hysteresis plate generates opposing resistance. This resistance results in the rise of torque. The angle of the permanent magnets allows for torque control. It is equipped with an excellent overload device for the driven parts. When torque is transmitted, it acts as a cushioning effect.

Electromagnetic brakes for conveying equipment and elevators, designed for emergency braking during power outages, without excitation operation.

The electromagnetic brake produced by Taiwan Sentai operates without excitation, ensuring safety and quiet operation. The standard models are available in three types: DC 24V, 90V, and 190V. Additionally, flexible customization is possible to meet customer needs. It ensures safe operation for elevators, cranes, conveyors, golf carts, and other lifting devices and electric vehicles. 【Features】 ● Safe and reliable braking force, suitable for both holding and braking With minimal torque variation, it can reliably operate even during emergency braking in the event of a power outage, making it an optimal safety brake. ● Quiet braking sound Designed to reduce high-frequency friction noise during braking, making it unobtrusive even in quiet environments. ● Adjustable torque By turning the built-in torque adjustment ring, a wide range of braking torque can be adjusted. The double braking structure ensures a minimum torque, maintaining safety. ● Usable in harsh environments By adding a rubber dust cover, it can brake normally even in adverse conditions. ● Manual brake release In the braking and holding state, pulling the release lever allows for manual brake force release. ● Long lifespan Utilizing materials with excellent wear resistance, it can operate stably for long periods without frequent adjustments. ● Easy installation and adjustment.

Small but high torque, quiet operation and long lifespan.

Compact and high torque, using special friction materials that result in low wear. The brake has a long service life. Its small size makes installation easy. Compliant with RoHS, the friction material is asbestos-free. When current is applied to the coil, the armature is attracted, releasing the brake. When the current is cut, the armature presses against the brake disc with the force of the coil spring, applying a sudden brake. As a specialized manufacturer of electromagnetic clutches and brakes in Taiwan, Sentai has been proposing and developing custom-made products to meet customer needs, leveraging the know-how cultivated over 30 years since its establishment.

Made in Taiwan! Easy and accurate torque control, with improved durability. Utilizing the electromagnetic hysteresis effect, it provides torque reliably and smoothly!

The CHB series utilizes the electromagnetic hysteresis effect to provide torque reliably and smoothly. The torque is generated in the electromagnetic gap rather than through powder or other friction components. This braking method offers outstanding characteristics, such as long lifespan, smooth torque, high repeatability of torque, and low maintenance costs, making it optimal for precise tension control systems. Features: - No directional restrictions for installation: Installation is easy and can be done freely according to the purpose, whether vertically or horizontally. - Capable of high-speed operation: Torque is generated by a non-contact structure, allowing for high-speed rotation. - Simple and accurate torque control: The ratio of torque to current is precise and can be adjusted freely. - High torque repeatability: Since torque is generated by electromagnetic force, the ratio of torque to current has high repeatability. - Smooth characteristics: The slip characteristics of torque during braking are smooth. - Long lifespan: There are no mechanical friction or wear issues, resulting in a long lifespan.

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm.
