Specification

The DELTA ASDA-B3 SERVO MOTOR ECM-B3M-20604RS1 400W is a core component of the ASDA-B3 series, designed to meet the rigorous demands of modern automation. This motor combines a 400W power rating with a 3000 RPM rated speed, delivering exceptional torque density and dynamic performance. Its 20-bit absolute encoder (standard for AC models) provides precise position control, while the lightweight, low-inertia rotor ensures rapid acceleration and deceleration. Ideal for applications requiring high precision, such as pick-and-place systems, labeling machines, and linear motion stages, the ECM-B3M-20604RS1 is built for durability and efficiency. Below is the detailed specification table derived from the DELTA B3 series standard data.
