{"product_id":"vlm21e-alnc-00","title":"VLM21E-ALNC-00","description":"\u003cp\u003eThe \u003cstrong\u003eKollmorgen VLM21E-ALNC-00\u003c\/strong\u003e servo motor from the \u003cstrong\u003eVLM Brushless Motors\u003c\/strong\u003e series delivers a compact, high-performance solution for industrial automation. With a maximum mechanical speed of \u003cstrong\u003e6000 rpm\u003c\/strong\u003e and a rated speed of \u003cstrong\u003e3000 rpm\u003c\/strong\u003e, this brushless motor supports dynamic motion control in demanding environments. The motor produces a continuous power output of \u003cstrong\u003e0.14 kW\u003c\/strong\u003e at rated speed and peaks at \u003cstrong\u003e0.26 kW\u003c\/strong\u003e for short bursts, enabling both sustained and high-power operations. Featuring a maximum current draw of \u003cstrong\u003e2.99A\u003c\/strong\u003e, the VLM21E-ALNC-00 balances electrical demands with robust torque capability of \u003cstrong\u003e0.48 Nm\u003c\/strong\u003e. Weighing only \u003cstrong\u003e1.4 kg\u003c\/strong\u003e, this servo motor provides an excellent power-to-weight ratio for space- and weight-sensitive installations.\u003c\/p\u003e\n\n\u003cp\u003eDetailed technical specifications define the VLM21E-ALNC-00's performance envelope with precision. The motor’s \u003cstrong\u003einertia (includes resolver feedback)\u003c\/strong\u003e is \u003cstrong\u003e0.429 kg-cm²\u003c\/strong\u003e, ensuring rapid acceleration and deceleration cycles, while its \u003cstrong\u003estatic friction\u003c\/strong\u003e torque of only \u003cstrong\u003e0.008 N-m\u003c\/strong\u003e minimizes startup resistance. With \u003cstrong\u003e3 pole pairs\u003c\/strong\u003e, the electrical-to-mechanical speed relationship is optimized for smooth torque delivery across the operating range. Thermal management is addressed through a \u003cstrong\u003ethermal resistance\u003c\/strong\u003e of \u003cstrong\u003e2.4 °C\/W\u003c\/strong\u003e and a \u003cstrong\u003ethermal time constant\u003c\/strong\u003e of \u003cstrong\u003e7.5 minutes\u003c\/strong\u003e, enabling reliable heat dissipation under continuous load. Viscous damping of \u003cstrong\u003e0.003 N-m\/krpm\u003c\/strong\u003e further stabilizes the motor’s response, reducing overshoot and oscillations in closed-loop control.\u003c\/p\u003e\n\n\u003cp\u003eOperational features emphasize performance, reliability, and responsiveness in precision automation tasks. The brushless design of this \u003cstrong\u003eServo Motor\u003c\/strong\u003e achieves low maintenance operation and extended service life, while the \u003cstrong\u003e0.48 Nm torque\u003c\/strong\u003e rating supports high-precision positioning and rapid repetitive motion. At peak output, the motor delivers \u003cstrong\u003e0.26 kW power\u003c\/strong\u003e for transient demands, automatically limiting current to \u003cstrong\u003e2.99A\u003c\/strong\u003e to safeguard against thermal overload. The low inertia value of \u003cstrong\u003e0.429 kg-cm²\u003c\/strong\u003e allows tight motion profiles and quick settling times, essential for multi-axis systems. Static friction and viscous damping parameters ensure smooth starts and stops, enhancing overall system accuracy and reducing mechanical wear.\u003c\/p\u003e\n\n\u003cp\u003eIntegration of the \u003cstrong\u003eVLM21E-ALNC-00\u003c\/strong\u003e into control systems is facilitated by standard resolver feedback and compatibility with common servo drives in industrial automation. This motor is ideal for applications in robotics, pick-and-place machinery, CNC tooling, and semiconductor handling where precision, speed, and compact form factor are critical. The combination of \u003cstrong\u003eKollmorgen\u003c\/strong\u003e engineering, brushless reliability, and the balanced specification set makes the VLM21E-ALNC-00 a versatile component for next-generation automation solutions.\u003c\/p\u003e","brand":"Kollmorgen","offers":[{"title":"Refurbished","offer_id":51963839545645,"sku":null,"price":3177.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0747\/7696\/9517\/files\/VLM_Servo_Motor_Series__01HRSRNZDMRQY31VY5PXAT179X_b54b5cdb-835f-4a52-8170-eb44ca5705b8.webp?v=1760641746","url":"https:\/\/servosupplier.com\/products\/vlm21e-alnc-00","provider":"Servo Supplier","version":"1.0","type":"link"}
