Product Description:
The R22HENA-R1-NS-NV-01 servo motor is produced by Pacific Scientific and belongs to the R Servomotors series. Designed for closed-loop industrial automation, it converts electrical power into precisely regulated rotary motion for pick-and-place heads, miniature conveyors, and high-speed spindles. A compact round frame and the lack of a holding brake keep the overall length short, making the unit suitable for mounting where space and weight must be minimized. This type of motor is well suited to axes that need quick response and accurate positioning during repetitive motion.
The motor develops a continuous stall torque of 0.6 Nm, giving a clear picture of the load it can hold without overheating during static positioning. Its circular housing measures 2.0" OD, so it fits standardized inch-based mounts without adapters. Rated mechanical output reaches 8000 rpm, and the low rotor inertia of 0.014 kg·m² × 10⁻³ supports rapid acceleration in index cycles. Permanent magnets made from rare-earth samarium cobalt provide high magnetic flux density while resisting demagnetization at elevated temperatures. A high-speed winding lowers electrical time constants, allowing the drive amplifier to supply current transitions quickly during vector control. The small round housing also helps the motor fit beside couplings, sensors, and other tightly spaced machine components.
For short bursts, the motor can deliver a peak torque of 1.62 Nm, accommodating momentary inertial mismatches during startup or quick directional reversals. Position feedback is supplied by a frameless resolver of transmitter type and size 15, providing rotor position data to the drive during operation. The electromagnetic stack is 2 inches long, which helps keep the overall package lightweight. Resolver feedback is also useful in electrically noisy environments because the signal remains stable under demanding industrial conditions. The absence of a shaft seal keeps the output end simple, and the inch-based mounting flange aligns with common fixture plates.
