This servo amplifier delivers a \u003cstrong\u003eRated Output of 4500 W\u003c\/strong\u003e and supports a \u003cstrong\u003eRated Revolution Speed of 2000 rpm\u003c\/strong\u003e, providing robust power and consistent velocity control. It is capable of producing a \u003cstrong\u003eRated Torque of 21.5 N·m\u003c\/strong\u003e while maintaining a manageable \u003cstrong\u003eWeight (including Wiring) of 22.0 kg\u003c\/strong\u003e, facilitating straightforward installation and handling. Designed for heavy-duty applications, the unit integrates an efficient \u003cstrong\u003eTorque Constant of 1.05 N·m\/Arms\u003c\/strong\u003e and a \u003cstrong\u003eRated Armature Current of 24.1 Arms\u003c\/strong\u003e to optimize dynamic response and control precision. The compact form factor offers installation flexibility without compromising on performance.\u003c\/p\u003e\n\n\u003cp\u003eTechnical capabilities of the PY9A050U0XXXC03 are highlighted by its electrical and mechanical specifications. It provides a \u003cstrong\u003eContinuous Stall Armature Current of 31.6 Arms\u003c\/strong\u003e paired with a \u003cstrong\u003eContinuous Stall Torque of 32.0 N·m\u003c\/strong\u003e, ensuring dependable torque delivery under prolonged load. For peak demands, the amplifier handles an \u003cstrong\u003eInstantaneous Maximum Stall Armature Current of 79.7 Arms\u003c\/strong\u003e and an \u003cstrong\u003eInstantaneous Maximum Stall Torque of 70.0 N·m\u003c\/strong\u003e, safeguarding against transient overloads. The device’s \u003cstrong\u003ePhase Armature Resistance of 0.043 Ω\u003c\/strong\u003e and an \u003cstrong\u003eInduced Voltage Constant of 36.7 V\/krpm\u003c\/strong\u003e are optimized for efficiency and rapid current control. The internal rotor dynamics are characterized by an \u003cstrong\u003eInertia (including Abs-e) of 58.2×10⁻⁴ kg·m²\u003c\/strong\u003e, while a \u003cstrong\u003eMechanical Time Constant (sensor Not Included) of 0.68 ms\u003c\/strong\u003e ensures swift acceleration and precise positioning.\u003c\/p\u003e\n\n\u003cp\u003eOperational features of this amplifier are tailored to maintain system stability and longevity. It supports a \u003cstrong\u003eMaximum Revolution Speed of 2500 rpm\u003c\/strong\u003e, extending operational range beyond the rated speed for short durations. The design includes fewer internal noise filters than earlier models, yet improved internal circuitry sustains a high level of electromagnetic noise suppression. For retrofit or replacement scenarios, implementing external noise filters on the \u003cstrong\u003e200 VAC power source\u003c\/strong\u003e is recommended to ensure maximum system stability. Absent an internal regenerative resistor, the amplifier accommodates external resistors for energy dissipation during deceleration; in their absence, the front-panel “CHARGE” indicator lamp signals a five-minute capacitor discharge interval upon shutdown.\u003c\/p\u003e\n\n\u003cp\u003eIntegration into industrial systems is streamlined by its robust construction and straightforward mounting requirements. Weighing in at \u003cstrong\u003e22.0 kg\u003c\/strong\u003e, the amplifier benefits from installation on a simple metal sub-panel—preferably \u003cstrong\u003ezinc plated metal\u003c\/strong\u003e or galvanized steel—for effective high-frequency grounding. To preserve longevity, avoid ingress of dust and debris by maintaining a clean environment or incorporating protective covers. When housed within an enclosed cabinet, ensure sufficient internal clearance or active cooling mechanisms to facilitate heat dissipation and uphold optimal operating temperatures.\u003c\/p\u003e","brand":"Sanyo Denki","offers":[{"title":"Refurbished","offer_id":51689754591533,"sku":null,"price":1100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0747\/7696\/9517\/files\/PY_Super_BL_Servo_Amplifiers__65de323f-ae54-4dd5-96e4-9042ec0de95c.webp?v=1760297577","url":"https:\/\/servosupplier.com\/products\/py9a050u0xxxc03","provider":"Servo Supplier","version":"1.0","type":"link"}
