Product Description:
The R46GSNA-TS-NS-VS-02 servo unit belongs to the R Servomotors series manufactured by Pacific Scientific. Designed for closed-loop motion control in industrial automation, it converts commanded current into regulated rotary torque for indexing tables, packaging axes, and material-handling joints. Its magnetic circuit and feedback interface let connected drives govern position, velocity, and acceleration precisely across repetitive duty cycles. This operating profile suits machines that require repeatable starts, stops, and speed changes during continuous production.
The motor delivers a continuous stall torque of 7.6 Nm, providing constant shaft force without overheating. During rapid acceleration, it can reach a peak torque of 20.2 Nm, allowing quick cycle starts. The square frame measures 4.25" square, which sets the mounting footprint for NEMA-style plates. Rotor inertia is 0.40 kg·m² × 10⁻³, balancing speed response with load stability. A set of rare-earth samarium cobalt magnets supplies high flux density and resists demagnetization under elevated temperatures. The housing style is standard, and the lamination stack supports the motor's continuous power output. Standard windings keep phase resistance within the expected range for the companion drive. The motor is supplied without a holding brake, so external mechanical retention is required whenever power is removed.
The primary feedback device is the Tachsyn resolver, which delivers proportional velocity signals for speed loops. There is no secondary feedback channel, which simplifies the wiring scheme and keeps the feedback arrangement straightforward. A Viton shaft seal protects the bearings from coolant splash and abrasive dust, helping the motor operate reliably where contamination can reach the shaft area. The magnetic core height of 6 inches contributes to thermal mass, helping the standard housing dissipate heat during continuous duty. These feedback and sealing features support stable motor operation in repetitive industrial service.
