Introducing the STR2 Stepper Drive

Apr

by Eric Rice

Applied Motion Products is pleased to announce the STR2 step motor drive. The STR2 is a compact, digital step & direction drive, great for OEM applications requiring basic step & direction control of a 2-phase stepper motor. The STR2 outputs up to 2.2 A/phase to the step motor, and is compatible with a variety of 2-phase step motors that have been selected to optimize performance of both the drive and motor.

The STR2 drive features advanced microstepping performance and sophisticated current control with anti-resonance. Anti-resonance electronically damps motor and system resonances, which improves motor smoothness and torque over a wide speed range.

Each STR2 step motor drive operates in either Step & Direction or Pulse/Pulse control mode. Selecting between these two modes is done by moving a jumper located under the cover of the drive. Each STR2 drive can microstep up to 20,000 steps/rev with a 1.8º step motor (1/100 step), and can even microstep the step motor when the command pulses are low resolution. This feature is called Microstep Emulation. All drive setup is done via dip switches on the side of the drive, including motor selection, running current, idle current, and step resolution.

The STR2 is RoHS compliant and CE certified. Matching step motors and DC power supplies are also available from Applied Motion Products.

50 piece pricing begins at $74.25
