Santa Clarita, CA —– Motion Control Tutorial – How Does a Linear Induction Motor Work? – Linear induction motor (LIM) theory is most easily understood as a rotary motor that has been cut and unrolled to generate linear motion, instead of rotary motion. It is comprised of two parts, the primary and secondary, which interact with one another only when power is applied. Either the primary or the secondary can be fixed while the other moves.

Understanding the specifications needed to properly size my motion control application –
Santa Clarita, CA —– Every motion control problem begins with a need to move a certain payload over a certain distance. However, there are many types of moves possible, and determining the right motion control solution may require some calculations to match the specifications found on a given motors data sheet. Most sales engineers will ask you for three basic questions when directing you to the proper motor or motion control solution.
Santa Clarita, CA — When three-phase AC power is applied to the primary, a travelling electromagnetic flux wave is induced and moves relative to the primary. The wave induces an electric current in the conductive reaction plate. The induced electric current interacts with the magnetic flux to produce a linear force. The speed of the motor can be varied by changing the input frequency using an adjustable frequency drive.
Santa Clarita, CA —– Linear Motion Control Components – H2W has developed an unhoused arc segmented frameless brushless torque motor (TWR-070-410-1150-3PH) with low inertia moving coil assembly for high angular acceleration applications.

Motion Control White Paper – A linear motor should be thought of as a rotary electric motor that has been cut along a radial plane and unrolled. The resultant motor is a direct drive linear electric motor that can produce linear motion without the need of pneumatic, hydraulic cylinders, or translation of rotary to linear motion with the use of belts or screws. Rotary motors produce torque whereas linear motors produce linear force.
