A Direct Drive Linear (DDL) motor is basically a rotary motor that is laid out flat and directly coupled to the driven load. By eliminating mechanical transmission components, this design delivers exceptional performance, stiffness, dynamic speeds and accelerations, positional accuracy, and throughput. DDL motors also enable compact mechanical assembly, quiet operation, zero maintenance and smooth, error-free motion.
Iron core linear motors have coils wound around silicon steel laminations to maximize the generated force with a single sided magnet way. These motors’ special electromagnetic design delivers the highest rated force per size, a high Km motor constant for low thermal losses, and low cogging forces. The high thrust forces possible with these motors make them ideal for accelerating and moving high masses, and maintaining stiffness during machining and processing.

Iron-less linear motors have no iron or slots for the coils to be wound on. Therefore, these motors have zero cogging, a very light, and absolutely no attractive forces between the coil assembly and the magnet way. These characteristics are ideal for applications requiring very low bearing friction, high acceleration of lighter loads, and for maximizing constant velocity, even at ultra low speeds. The modular magnet ways consist of a double row of magnets to maximize the generated thrust force and to provide a flux return path for the magnetic circuit.
