Frame 56HZ RPM 3450","description":"\u003cp\u003eThe Castair 5-56Z-1H is a 5 HP Open Drip Proof (ODP) electric motor running at 3450 RPM on 208\/230V single-phase power, with a 56HZ NEMA frame. This is the high-speed motor variant in the Castair 5 HP single-phase lineup — running at 3450 RPM rather than the 1725 RPM of the 184T frame models. At $546.35, it is also the lower-cost option in the 5 HP single-phase range, which reflects the smaller frame size and simpler 2-pole construction.\u003c\/p\u003e\u003ch2\u003e3450 RPM vs. 1725 RPM: What the Difference Means\u003c\/h2\u003e\u003cp\u003eA 3450 RPM motor is a 2-pole design running at approximately synchronous speed for 60 Hz power. A 1725 RPM motor is a 4-pole design running at half that speed. For compressor applications, the motor speed determines how the drive pulleys must be sized to reach the target pump RPM. Higher-speed motors use smaller drive sheaves and can be more compact, but they also place more demand on belt life and generate higher vibration frequencies. If Cast Air specifies a 3450 RPM motor for your compressor model, that is the correct replacement — the pulley ratio is designed around that motor speed.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e5 HP output:\u003c\/strong\u003e OEM power rating for applicable Castair compressor models using the 56HZ frame\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e208\/230V single-phase:\u003c\/strong\u003e Runs on standard shop single-phase service\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3450 RPM:\u003c\/strong\u003e 2-pole high-speed motor — matched to the drive system of applicable compressors\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNEMA 56HZ frame:\u003c\/strong\u003e Compact frame size — verify mounting dimensions match your compressor installation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpen Drip Proof enclosure:\u003c\/strong\u003e Ventilated cooling for clean, dry indoor environments\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCastair OEM specification:\u003c\/strong\u003e Correct motor for applicable Cast Air compressor models\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHorsepower:\u003c\/strong\u003e 5 HP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 208\/230V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhase:\u003c\/strong\u003e 1-phase (single-phase)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRPM:\u003c\/strong\u003e 3450\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNEMA frame:\u003c\/strong\u003e 56HZ\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnclosure:\u003c\/strong\u003e ODP (Open Drip Proof)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Cast Air \/ Castair\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSKU:\u003c\/strong\u003e 5-56Z-1H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrice:\u003c\/strong\u003e $546.35 — call for pricing and availability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFrame Size Note\u003c\/h2\u003e\u003cp\u003eThe 56HZ frame is smaller than the 184T frame.
