Product Description:
PS 90/6-57-P-4843 is an advanced synchronous motor operated from single-phase AC> using an RC phase shifting network. This motor variant is from the <
The module achieves nominal speed of approximately 72RPM at 60Hz and 60RPM at 50Hz, thus supports predictable speed control in low-speed applications. Its torque rating ranges from around 240oz‑in (169Ncm) to 700oz‑in (494Ncm) for the 90 Series. It further carries an IP42 enclosure rating that protects internal components from solid foreign objects. The object operates continuously from -40F to 140F (-40C to 60C) and sustains a maximum shell temperature of 212F (100C). It is also available with leads or a terminal box (the “P” designation indicates a terminal-box design). This starts, stops, or reverses within 1½ cycles of the applied frequency provides rapid responsiveness. It is built ruggedly with double shielding and ball bearings in an ISO9001 environment, ensuring consistent construction quality.
PS 90/6-57-P-4843 offers rear shaft extensions and gearmotor options, which extend application versatility. It achieves a rated efficiency of 92%, further minimizes energy losses during operation. The device maintains a service factor of 1.0 for indicating stable performance under rated loads. This motor also features a foot-mounted design that simplifies integration into machinery. It weighs approximately 150lbs., and balances robust build with manageable installation.
