Product Description:

The high-torque brushless servo motor Pacific Scientific S32GNAA-RNVE-00 is part of the S series.

It is built on the NEMA 34 frame, and is distinguished by its longevity and precise motion control. Its motor uses a two-stack motor, which guarantees compactness while also increasing output torque. Because it only weighs 4.9 kg, integrating it into other systems is very simple. Performance during stalled conditions is reliable due to a fixed stall torque of 4.0 Nm. It can sustain short-term high load requirements and reaches a highest torque of 11.3 Nm. These qualities are appropriate for severe automation tasks requiring control and power. Electrically, the motor is optimized towards the production of high-efficiency torque. The motor has an inductance between its windings of the motor of 18.0mH, which helps to make the motor smoother as it filters out fast variations of current. It also possesses a resistance of 6.2 ohms, and it contributes to stability, but may result in slowing the electrical response and producing a higher current ripple. The motor possesses a high torque constant of 1.3 Nm/ARMS, whereby it achieves high torque at a relatively low current value.

It has 0.82 VRMS/rad/sec as its voltage constant that helps in producing efficient torque and is important in controlling thermal performance and system life extension. The rotor's torque performance is enhanced, and medium-to-heavy inertial loads may move steadily thanks to its 0.34 x 10⁻³ kg· m² of inertia. A sturdy and dependable industrial device, the frameless Size 21 resolver, is used to handle feedback. Secondary feedback device is absent, and applications that need high-resolution feedback will have to make up with supplements. The motor has a Viton shaft seal to prevent fluids and dust, and it can operate in more demanding conditions. Terminating is appropriate for systems that have already standardized on that interface and is accomplished through Interconnection connectors.
