Lin Engineering's new 4518 NEMA 17 stepper motors are designed exclusively with the company's patent-pending Signature Series technology and are the new and improved version of Lin's 4118 motors. The 4518 series is available in three different stack lengths starting with the 4518S at 1.34 inch in thickness and the 4518L measuring in at 1.89 inch. Depending on the stack length, these motors are capable of producing up to 83 oz-inch of holding torque. The new series is suggested for use in applications where size is a factor and load capacities are critical to precision system operation. Industries currently benefiting from the features of this motor in their applications are medical, printing, imaging, optical and robotics. Lin's Signature Series was developed to help reduce system resonance and provide overall smooth motion. Depending on the application, using motors with the Signature Series technology may result in up to 50 percent less resonance being produced.
