Product Overview

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.
