Product Description:
The R32GSBC-R2-NS-VS-02 servo motor is manufactured by Pacific Scientific and belongs to the R Servomotors series. It is intended for industrial automation tasks that require accurate motion profiles and repeatable positioning. By converting drive current into controlled mechanical rotation, the motor moves actuators, tables, or spindles with minimal position error. Its square frame and sealed shaft arrangement allow it to fit within tight mechanical spaces while resisting airborne contaminants commonly found on production floors.
The motor can deliver a continuous stall torque of 1.7 Nm, allowing it to hold a stationary load without exceeding its continuous thermal capacity. During acceleration or shock loading, output rises to a peak torque of 4.40 Nm, permitting short bursts of higher force before thermal limits are reached. The rotor inertia is 0.071 kg·m² × 10⁻³, so the motor can change velocity quickly while limiting overshoot. The frame measures 3.25 inches square, providing a compact mounting footprint for machinery with limited installation space. At its rated speed of 4000 rpm, the shaft supports high-speed motion for automated equipment. The windings are matched to the rare-earth magnetic field to reduce cogging during rotation.
An integral 100 V DC brake locks the shaft when brake power is removed, preventing vertical or suspended loads from drifting. Magnetic flux is generated by samarium cobalt magnets, which maintain high remanence at elevated temperatures. A Viton shaft seal sits behind the front bearing to retain lubricant and prevent fine dust from entering the housing. The laminated stack has a length of 2 inches and uses a style C housing with a standard winding pattern. This combination of copper volume and thermal mass supports moderate duty cycles. Primary position feedback is supplied by a frameless size-21 resolver transmitter, which provides rotor position information to the drive. The motor has no secondary feedback channel, reducing the number of feedback connections required in the control system.
