4.5 N·m Integrated Closed Loop Stepper, 86 mm Frame

Overview

The iHSS86-60-45 is a 4.5 N·m Integrated Closed Loop Stepper on an 86 mm frame with an 80 mm body. The driver and motor share one housing, and servo-style control is implemented inside the digital stepper drive for real-time position correction. This arrangement gives machine builders the torque of an 86 mm motor with the wiring simplicity of an integrated unit.

Encoder Feedback

Position information comes from a 1000 P/R incremental encoder. The closed loop compares the commanded and actual position and corrects the output continuously, which keeps the axis accurate under variable load and supports fast acceleration without step loss. Because the loop verifies every move, the axis stays repeatable even when product weight changes between batches.

Key Specifications

• Frame size: 86 mm
• Body length: 80 mm
• Holding torque: 4.5 N·m
• Rated current: 6.0 A
• Feedback: 1000 P/R incremental encoder

Torque and Thermal Characteristics

With 4.5 N·m holding torque and a 6.0 A rating, the unit fits medium-torque automation tasks. Low heat generation keeps the machine assembly cool, and the low-vibration design protects precision mechanisms during high-speed indexing. The short 80 mm body is an advantage when the motor must sit inside a compact frame or move with the carriage.

Applications

Typical uses are factory automation, packaging machinery, robotics and CNC machine tools. The 4.5 N·m integrated class also covers conveyor diverters, small rotary tables and shuttle drives in packaging and robotic cells, where a separate servo amplifier would add unnecessary cost and panel space.

Selection Considerations

Verify the 86 mm flange and 80 mm body length against the machine, and confirm the 6.0 A feed and DC supply voltage. Check the torque-speed curve at the operating point, and confirm the controller can accept the incremental encoder signal.
