Why Use Linear Motors
A Linear Motor is an electrical motor designed to produce force in a straight line. The construction of a linear motor is close to that of a standard rotating motor, but in a linear form.
There are several key advantages of using Linear Induction Motors. As the stator and rotor are not in physical contact with one another there are no moving parts, operation is silent, and there is no frictional wear of the motor system, which combine to give greatly reduced maintenance costs. Further advantages include compact size, simple and inexpensive control methods and ease of installation.
Forcepack Linear Induction Motors are extremely customizable to suit customer requirements. LIMs have been developed that can produce thrust from just a few Newtons to tens of thousands of Newtons, with inputs from 0.5 amps at 100V single phase to thousands of amps at 660V 3 phase, working at speed ranges from millimeters per second to 100s of metres per second. Sizes vary from a few square inches to many square feet; from a few VA to an experimental unit of 3.5MVA. This means that Force can accurately move a single steel bar a few millimeters or propel a 7 tonne vehicle from 0-60mph in under 4 seconds.
