Overview
The design of LinStep and LinStep+ microstepping motor drivers (also called a
driver or control) and the internal cooling tunnel are revolutionary.  These drivers
consume less panel space than other controls and keep internal electronics cool
and clean for years of reliable performance and operation.  LinStep+ single and
dual–axis drivers are used with Baldor motion controls and other popular stepper
controllers that provide step and direction (or CW/CCW step pulses) .  They are
ideally suited to control Baldor single and dual–axis linear stepping motors.  Figure
2-1 shows how the LinStep+ driver is placed in a linear stepper motor system.
The open loop linear stepper motor provides the most economical linear motor
positioning solution. There are two types of linear stepper motors: a single–axis
linear stepper motor and the compact dual–axis linear stepper motor. Linear
stepper motors include the motor, positioning system and bearings in two
components: a moving forcer and a stationary platen.

Linear stepper motors move in discrete incremental moves called steps. The size
of each step is determined by the spacing of the teeth in the platen and how the
coils are energized. Baldor 2–phase motors travel 0.010 inches (0.254mm) in a
single full step yielding 100 steps per inch. Baldor 4–phase motors travel 0.005
inches (0.127mm) in a step. When the coils are energized in a predetermined
pattern, the forcer will move down the platen. Reversing the pattern will reverse
the direction of travel. The microstep frequency determines the velocity of the
forcer. Linear stepper motors produce their maximum force at zero speed. As
speed increases the ability to switch winding current decreases due to motor
inductance. This results in lower forces at higher speeds.
