These motors, having a large axial hole
throughout the entire coil and body structure are
ideal for optical focusing, scanning and other
precision positioning applications.
These motors consist of two separate parts; the
magnetic housing and the coil. Applying a voltage
across the terminals of the motor causes the motor to
move to one direction. Reversing the polarity of the
applied voltage will move the motor to the opposite
direction. The generated force is proportional to the
current that flows through the motor coil. This force
is almost constant in the specified stroke range of
the motor.
