Not all
linear motors are created equal
Linear motors, the idea is simple
enough. Take a conventional rotary servo motor and unwrap it. So now
what was the stator is now a forcer and the rotor becomes a coil or
magnet rail. With this design, the load is connected directly to the
motor. Direct linear motion is achieved without any rotary to linear
transmission devices.

Air-Core Linear Motor
Ironless linear motors are also known as air-core
linear motors. Ironless motors are characterized by having no
attractive force towards the magnets. A coil assembly
typically moves between two opposite facing rows of magnets.

Iron-Core Linear Motor
Ironcore linear motors
can produce the large forces needed for many industrial
applications. With this force comes an even larger force
between the coils and the magnets. Ironcore motors use steel
alloy laminations to concentrate and focus the magnetic flux
but also produced a large attractive force. The coil must be
held off the magnet track by about 1mm through the use of
mechanical or air bearings |

|
Slotless Linear Motor
Slotless motors have a lower
attractive force and a corresponding lower force constant than
ironcore motors. The lower attractive force permits the use of
smaller linear bearings during mechanical assembly. Slotless
motors are less expensive than ironcore motors and are
competitive with most ball screw or timing belt
solutions.

Tubular Style Linear Motor
Tubular style linear
motors have round magnets embedded inside a hollow stainless
steel shaft (or rod). The forcer floats on this shaft with a
1mm annular airgap. This compact cross section makes it ideal
for ballscrew conversions. |
