The R22HSNA-R1-NS-NV-04 is a 4 pole synchronous servo motor, produced by Pacific Scientific. It utilizes rare earth magnets of samarium cobalt providing an optimal torque-to-inertia ratio, ensuring high quality dynamic response. Despite its impressive power, this motor is housed in a compact unit, ideal for applications catering to limited installation spaces. The mounting type and shaft, motor sequence number, and transmitter type are factory predetermined. It also incorporates a Frameless resolver with a primary feedback size of 15. The motor operates on a maximum 320V DC bus, has an 18-inch lead with MS type connectors, and is equipped with an anti-cog stator design. Safety provisions include a thermistor for protection against overheating, and Class H insulation providing operational resilience under suboptimal conditions. Built-in "O" rings serve to extend bearing life, and the motor offers a torque range of 0.3 to 1.1 Nm at speeds reaching 11,000 RPM.
