Brakes and clutches with lifesaving capabilities and motion control systems are critical aircraft elements. They not only help pilots navigate smoothly during challenging weather conditions, but they also play a lifesaving role during mid-air emergencies. SEPAC products are developed with reliability at the forefront of design and, through a partnership with Genesys Aerosystems, have helped […]

In the past, pneumatic and hydraulic systems have been the most common actuator types for aircraft due to their high power density and cost-effectiveness. However, in recent years, attention has been focused on the limitations of these systems, including their level of performance, weight, high maintenance requirements, and more.  Recent advances in electromagnetic actuator technology […]

As the demand for smaller motors increases, so does the need for small-diameter brakes and other small components. With recent technological advancements, electromagnetic brakes are able to generate powerful torque even in compact sizes. SEPAC is recognized for our capability to customize standard brake and clutch products to meet the application requirements of our customers. […]

Robotics is rapidly advancing, with new developments and capabilities emerging every day across multiple sections of this industry. Applications ranging from oil and gas excavations to military and transportation projects rely on underwater robotics to achieve explorative missions, maintenance, and more. Today’s electronic and electrical based robotics systems offer fine-tuned movements, powerful motion, and new […]

Brakes are essential to diverse industries for slowing and stopping motion or holding various loads in place. Electromagnetic brakes specifically use the presence and absence of electric current and magnetic field to release or lock brakes into place, holding or stopping a load when the electric current shuts down. This type of power-off brake is […]

Click to Expand Control fins on the bodies of missiles adjust their flight path and help ensure missiles hit their intended targets. The main component used to position these fins is a missile fin actuator, which maneuvers the fins according to a missile’s onboard processor instructions. As there can be no room for error when […]

SEPAC, Inc is honored to partner with Motiv Space Systems, Inc. on new technology for future flight missions, including space flight. Through the Small Business Innovation Research (SBIR) Sequential Phase II Program, Motiv Space Systems has been awarded a $5 million contract with the National Aeronautics and Space Administration (NASA) to develop the Distributed Extreme […]

There are two basic types of Electromagnetic Brakes. “Power On” (Magnetically Engaged) and “Power Off” (Spring Engaged). Most brakes (covering several markets) work with Direct Current applied (DC). 24VDC is popular. When power is applied an Electromagnetic Field is generated. This field has a normal force created by the strength of the coil (magnetic flux) […]
