Linear motor-Types and construction . Linear Servo Motors are frameless permanent magnet three phase brush-less servo motors. They are, fundamentally, rotary motors that are rolled out flat. In linear motor the rotor rolled out to become a magnet track. The rotary stator became linear motor …
Rpm stands for rotations per minute and is used to quantify the speed at which an object spins, such as a motor or a centrifuge. Linear speed measures the actual distance traveled, often in feet per minute.
Known variables: Weight (lbs), Linear Velocity (ft/min), Speed of Driving Motor (RPM), Change in Speed (RPM), and Time to Accelerate Total System (sec) In addition to the torque required to drive the load at a steady speed, torque is required to accelerate the load.
A linear induction motor (LIM) is an alternating current (AC), asynchronous linear motor that works by the same general principles as other induction motors but is typically designed to directly produce motion in a straight line. Characteristically, linear induction motors have a finite primary or secondary length, which generates end-effects ...

A linear induction motor (LIM) is a non-contacting, high speed, linear motor that operates on the same principal as a rotary, squirrel cage, induction motor. They are capable of speeds up to 1800 in/sec [45 m/s] and are typically used in applications where accurate positioning is not required.
The basic construction of a linear induction motor is similar to a three phase induction motor but it does not look alike a conventional induction motor. If we cut the stator of a polyphase induction motor and lay on a flat surface, it forms the primary of the linear induction motor system.

The operation of a DC motor is relatively straightforward. A coil is placed in a magnetic field, and when an electric current passes through the coil, a torque is produced, causing the motor to turn. The entire process is driven by applying electrical power to the coil, with the source voltage having a direct relationship to the motor's output speed.
