REXRTOH SYHNC100-NIB-22A/W-24-P-D-E24-A012: Engineered for Precision Servo Control

The REXRTOH SYHNC100-NIB-22A/W-24-P-D-E24-A012, identifiable by the manufacturer article number R900978416, is a sophisticated brushless synchronous motor designed specifically for servo applications. This motor belongs to the performance-oriented SYHNC series and represents a complete motion solution that integrates the motor, high-resolution feedback, and standardized mechanical interfaces into a single, compact unit. Its design is focused on providing exceptional dynamic response, precise positional accuracy, and reliable operation in repetitive motion tasks, making it a key component in modern automated systems where movement must be both exact and repeatable.

Core Technology and Servo Operation

This motor is a Permanent Magnet Synchronous Motor (PMSM). Its operation relies on the interaction between a permanent magnet rotor and a stator with carefully arranged windings. When powered by a compatible servo drive, the drive supplies a three-phase sinusoidal current to the stator windings, creating a rotating electromagnetic field. The permanent magnet rotor synchronously follows this field. The "NIB-22A" and "D" designators in the model number signify a specific, integrated high-resolution rotary encoder. This encoder provides continuous, real-time feedback on the rotor's exact angular position and speed to the servo drive, enabling true closed-loop control. This feedback loop allows the drive to continuously adjust the current to correct for any deviation between the commanded and actual position, resulting in unparalleled precision.

Key Features and Performance Benefits

• High Dynamic Performance: Features low rotor inertia, enabling very high acceleration and deceleration rates for rapid cycle times in pick-and-place and indexing applications.

• Exceptional Positional Accuracy: The integrated encoder provides the feedback necessary for precise positioning, often with resolution down to arc-minutes or better, ensuring repeatable movement.

• Continuous Torque Output: Delivers smooth, consistent torque across a wide speed range, from near-zero rpm to high speeds, without the torque ripple common in other motor types.

• Compact and Efficient Design: The brushless PMSM architecture offers high power and torque density in a small frame size (SYHNC100), along with high electrical efficiency that minimizes heat loss.

• Robust Industrial Construction: Built with high-quality bearings, durable housing, and reliable connector systems (as per E24-A012) to withstand vibration and harsh industrial environments.

• Simplified Integration: The standardized mechanical interface (implied by E24-A012) and pre-attached feedback connector allow for straightforward mechanical mounting and electrical connection.

• Maintenance-Free Operation: As a brushless design, it eliminates the wear and maintenance associated with brushed motors, ensuring long service life and reduced downtime.

Technical Specifications

Typical Applications in Automation

The SYHNC100-NIB-22A motor is engineered for a vast array of precision motion control tasks. In robotics, it acts as a joint actuator for precise arm movement. Within automated assembly and test equipment, it drives lead screws and belt drives for precise linear positioning. It is ideal for the controlled movement of tools in CNC machines, for spindle orientation, or for controlling gates and valves in process automation. The packaging industry utilizes it in servo-driven capping, labeling, and filling machines. Its precision also makes it suitable for medical and laboratory automation, such as in diagnostic equipment or sample handling systems, where smooth, accurate, and reliable motion is critical.

Integration with Servo Drive Systems

To unlock its full potential, this motor must be paired with a matching servo drive or amplifier from REXRTOH or a compatible third-party manufacturer that supports synchronous motor control. The integration process involves: 1) Mechanically mounting the motor and coupling it to the load with proper alignment. 2) Connecting the motor's power terminals (typically U, V, W) and ground to the drive's output. 3) Connecting the motor's encoder feedback cable to the drive's feedback input. The drive must then be correctly configured with the motor's specific parameters (e.g., pole pairs, encoder resolution, rated current, torque constant). This setup allows the drive to perform precise current vector control, transforming speed/position commands from a master controller (like a PLC) into the high-fidelity motion output of the motor.
