Product Description:

The R32HSNG-TS-NS-NV-02 is a rotary servo motor manufactured by Pacific Scientific and supplied as part of the R Servomotors series. This model is intended for closed-loop motion tasks in industrial automation, where precise velocity and position control are critical for material handling robots, labeling heads, and small gantry axes. When paired with a matched drive, the unit delivers responsive torque that advances or holds mechanical loads according to program requirements.

At the shaft, the motor sustains a continuous stall torque of 1.7 Nm, permitting it to hold loads indefinitely without overheating when airflow is adequate. For transient moves, it can produce up to 4.40 Nm, supplying the extra momentary force required to accelerate fixtures or overcome friction. The windings use the High Speed design code, supporting operation at a rated velocity of 7000 rpm while keeping iron loss within drive limits. Despite this output capacity, the housing occupies only a 3.25 in square frame, simplifying direct mounting into compact machine envelopes. Because the unit ships without a holding brake and without a shaft seal, any static locking or environmental protection must be provided by external hardware.

The rotor’s inertial value is limited to 0.071 kg·m²×10⁻³, allowing the drive amplifier to reverse direction quickly without large current spikes. Magnet excitation relies on samarium cobalt rare-earth material, which maintains flux density across a wide temperature range and resists demagnetization during rapid cycling. A stack length of 2 inches gives the stator sufficient thermal mass for continuous duty while keeping overall weight low. Position and velocity data are provided by a Tachsyn resolver, and no secondary feedback channel is included, so controller algorithms rely on this single device for correction. This arrangement keeps the feedback system simple and supports closed-loop control through one primary sensing element.
