The need for precise motion control is driven by many demands now placed on the line, from moving products around on the manufacturing floor to a variety of work stations to the logistics of moving the finished product through a facility.
From the outside it looks just like any other industrial brushless servo motor but inside it utilized advanced manufacturing techniques to provide higher torque, higher speed, smoother operation, higher efficiency, and better inertial matching in a smaller package.
To understand these benefits, we start with the basic concept of direct drive whereby the force of a motor is directly applied to a mechanism without any intermediate drive train such as a gearbox or toothed belt etc. The core working principles of direct drive motor technology is in essence based on the right hand rule of electromagnetism, whereby a current moving through a wound coil creates a magnetic field.
A traditional gantry system employs X-Y or X-Y-Z range of motion. Mounted on a base plate, usually granite, 2 parallel rails constitute the synchronized Y axis motion while the cross axis (bridge axis) provides the X motion. A vertical axis can be added on the bridge for the Z motion. A Split Bridge system can be less complex than a traditional gantry system because synchronization of the two parallel linear motors is not required. Both systems are used in industrial production, testing, and additive manufacturing.
