Q2AA18350HXS00M

The Sanyo Denki Q2AA18350HXS00M servo motor of the Q SANMOTION Servo Motors series delivers precise motion control with a rated output of 3.5 kW at rated speed of 2000 min⁻¹. Its robust design yields a continuous stall torque of 21.1 N·m and supports a peak torque of 55 N·m for high-demand acceleration profiles. Engineered for industrial automation, the Q2AA18350HXS00M integrates advanced electrical and mechanical parameters to maintain stable operation under varying loads. The unit’s torque constant and voltage constant ensure predictable responsiveness, making it an ideal choice for precision-driven equipment. Its compact footprint and standardized mounting allow seamless retrofitting within existing machinery.

The technical specifications of this servo motor underscore its performance: it features a torque constant (kt) of 0.840 N·m/Arms, and a voltage constant (keφ) of 29.3 mV/min⁻¹ that stabilizes electrical output. The continuous stall current (is) is 28 Arms while the rated current (ir) is 22.6 Arms to support sustained operation. Its peak current (ip) of 80 Arms accommodates brief high-load events without overheating. The phase resistance (rφ) of 0.045 Ω minimizes energy dissipation, improving efficiency. With an inertia (jm) of 37.89 × 10⁻⁴ kg·m², dynamic response and smooth torque delivery are optimized. The motor achieves a maximum speed (nmax) of 3500 min⁻¹ and maintains a rated speed (nr) of 2000 min⁻¹, driving rapid indexing movements.

Operationally, the Q2AA18350HXS00M excels in applications demanding quick acceleration and deceleration enabled by its rated power rate (qr) of 73.7 kW/s. The integrated aluminium plate dimensions of t20×470 mm promote efficient heat dissipation, facilitating continuous high-output cycles. Its mechanical construction endures repetitive start–stop sequences while preserving torque accuracy and minimizing vibration. Consistent torque output across the operating range reduces positional deviation, and the peak torque margin ensures transient loads are safely managed. The motor’s design also simplifies thermal management, eliminating the need for external cooling in standard ambient conditions.

System integration is straightforward via standard servo drive interfaces, enabling real-time tuning and feedback loops in advanced controllers. The unit’s precise speed and torque control suit robotics, CNC machinery, and automated assembly lines. Maintenance requirements are minimal, thanks to its low phase resistance and robust aluminium cooling plates. Overall, the Q2AA18350HXS00M supports scalable deployment in diverse industrial automation environments where reliability and accuracy are paramount.
