Product Description:
The R45HMNA-TS-NS-NV-00 is a brushless servo motor produced by Pacific Scientific within the R Servomotors series. It is a servo motor intended to deliver controlled rotation in automated pick-and-place stations, indexing tables, and coordinated gantry axes. By combining a compact electromagnetic stack with rare-earth magnets, the unit provides precise torque while maintaining a small footprint. This layout supports repeatable starts, stops, and directional changes in machinery that depends on accurate motion over short cycle times.
Its continuous stall capability reaches 5.7 Nm, meaning the shaft can hold that torque indefinitely without exceeding thermal limits. When rapid acceleration is required, the motor can deliver up to 15.1 Nm of peak torque for short periods. The rotating mass is limited by an inertia of 0.31 × 10−3 kg·m², which helps the axis respond quickly to speed and position commands. A winding coded for high-speed operation allows higher electrical frequency before back-EMF saturation, supporting faster mechanical output. Position and velocity signals are produced by a Tachsyn resolver, giving analog feedback compatible with legacy Pacific Scientific drives. This feedback method supports stable closed-loop operation in systems that use analog signal processing rather than newer digital encoder formats.
The motor uses a 4.25-inch square frame with a stack length of 5 inches, giving a clear installation envelope for machine layouts. Installation aligns to a metric mounting pattern, which helps the motor fit equipment built around international dimensions. Rare-earth magnets made from samarium cobalt sustain flux density at elevated temperatures, supporting consistent performance during demanding duty cycles. The motor has no shaft seal, and the housing uses a standard style, so added enclosure protection may be needed in wet or contaminated areas. It is supplied without a holding brake and without secondary feedback devices, which keeps the connection scheme simple and leaves stopping functions to the drive system.
