Motors • Linear Motors

A linear motor, or linear induction motor, is an alternating current (AC) electric motor that features an unrolled stator, allowing the motor to produce linear force rather than torque. Linear motors are used in a number of industrial applications including office and factory automation, medical science/lab instrumentation, optics, fast beam steering, wire bonding equipment, electronics, semiconductor equipment, and renewable energy. Specifically, tubular linear motors are be used in dirty industrial environments because of their ruggedness. There are two major linear motor design types: low acceleration and high acceleration. Low-acceleration linear motors are suitable for trains and other ground-based transportation applications. High-acceleration linear motors – used in rollercoasters - are designed to accelerate an object up to a very high speed and then release it.
