This motor features a \u003cstrong\u003e24-bit incremental optical encoder\u003c\/strong\u003e that provides high-resolution feedback to the control system, ensuring precise positioning and velocity regulation. Designed with a standard 130 mm frame size, it outputs a rated power of \u003cstrong\u003e2 kW\u003c\/strong\u003e at a synchronous speed of \u003cstrong\u003e2000 rpm\u003c\/strong\u003e under a 220V supply voltage. Equipped with a built-in electromagnetic holding brake and a specialized oil seal, this unit is built to maintain system integrity in vertical axes and demanding environments.\n\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul style=\"list-style-type: square;
