Connects via standard NEMA 23 mount for easy integration into motion control systems. Interfaces through standard electrical connectors to controllers and drives. Commonly used in CNC machines, robotics, and automated assembly lines for precise motion control. Capable of micro-stepping to enhance smoothness and accuracy of movement. Utilizes advanced magnetic design to optimize thermal performance and efficiency in various industrial applications.

Platforms

Designed for industrial automation systems requiring precise positioning control, commonly integrated into CNC machines, robotic assemblies, packaging equipment, and manufacturing production lines. Operates with step motor controllers and drives that provide digital pulse commands for incremental angular movement. Interfaces through standard electrical connections for power and control signals from PLCs, motion controllers, or dedicated step motor drives. Mounting configuration allows direct coupling to mechanical loads, gear reducers, or belt drive systems. Suitable for applications demanding accurate positioning without feedback sensors in controlled load environments.

Applications

Precision positioning in automated machinery, robotics motion control systems, CNC machines for metal and wood fabrication, semiconductor manufacturing equipment, and laboratory automation devices requiring precise control of linear or rotary motion.

Accessories

Requires 24VDC power supply, step/direction controller or indexer, shielded motor cables with proper gauge for current rating. Mounting hardware includes face mount or NEMA frame adapter brackets. Optional encoder feedback requires 5VDC supply and differential line driver interface. Motor connections via 8-pin connector or flying leads depending on model variant. Brake models require separate 24VDC brake power supply and brake control relay.

Interfaces

The step motor uses a quick disconnect (IDC) cable for motor wiring with standard wire color coding: Red/Black (B-), Red/White (B+), Green (A-). Interface includes keypad connector pins for setup and configuration, allowing adjustments of motor current, unloaded anti-resistance, and inductance via keypad commands. Compatible with 17 to 42 frame step motors, supporting up to 8A motor current with microstepping control. The system interfaces through 120V AC microstepping drive electronics, requiring connection to a compatible Danaher Motion SmartStep drive mainframe or equivalent power/controller.
