Motion control systems are vital to the proper function of aerospace and defense machinery and devices. These systems can control the velocity or position of a machine utilizing a range of movement technology, including servo motors, electric motors, and linear actuators. The aerospace and defense sectors rely on electromagnetic brakes and clutches for a variety […]

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. […]

Click to Expand The first step in fixing something is to understand how it works. Permanent magnet brakes (PMBs) are a form of brake that uses permanent magnets to provide the normal magnetic force necessary to attract the armature and produce torque. Permanent magnet brakes are used to hold or stop a load. Also called […]

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) […]

Robotics applications are quickly increasing and advancing, and these automation trends are being influenced by consumer demand and preference. From a modern lifestyle that prioritizes speed and convenience to companies that can’t manage the risk of a large upfront investment, there are underlying trends shaping the robotics of the future—and today.  Consumer Demand Calls for […]

Permanent magnet brakes (PMB) and spring engaged brakes (SEB) are safe and efficient braking mechanisms for halting and holding a load in place. They work in the absence of power and have distinct features that make them ideal for a range of applications. When selecting the ideal brake solution for an application, it is vital […]
