<Discription>

The Autonics 04K-S525 is a compact, high-precision 5-phase stepper motor designed for applications requiring reliable torque in a miniature form factor. With a 24mm frame size, it offers a holding torque of 0.28 kgf·cm (0.028 N·m), providing more power than the ultra-thin 02K series while remaining extremely compact. The standard Single Shaft configuration optimizes the motor's installation depth, making it an excellent choice for equipment where rear-shaft accessories are not required and space is at a premium. Operating at a rated current of 0.75 A/Phase, it ensures energy-efficient performance with the smooth rotation characteristic of 5-phase motors.

Key Features

• Compact High Torque: Delivers 0.28 kgf·cm (0.028 N·m) of holding torque in a 24mm frame, suitable for small loads requiring stability.

• Single Shaft Design: The standard single shaft configuration minimizes the overall length and complexity, ideal for blind-hole mounting or tight enclosures.

• Miniature 24mm Frame: Fits into tight spaces in compact machinery where standard 42mm motors are too large.

• Rated Current 0.75 A/Phase: Designed for energy efficiency and low heat generation.

• Precision 5-Phase Control: Supports a basic step angle of 0.72° (Full step) and 0.36° (Half step) for high-resolution positioning with low vibration.
