Specification

The Delta ECMA-C20604SS is a 400W low-inertia servo motor engineered for demanding industrial automation tasks requiring rapid acceleration, high precision, and reliable torque delivery. As part of the renowned ECMA series, this motor features a 20-bit incremental encoder that ensures exceptional feedback resolution, enabling tight position control and minimal settling time. The ECMA-C20604SS operates at a rated speed of 3000 rpm and delivers a continuous torque of 1.27 Nm, making it an excellent choice for applications such as pick-and-place machines, packaging equipment, and CNC routers. Its low-inertia rotor design minimizes mechanical time constants, allowing for quick response to command changes. This model comes without a holding brake and without an oil seal, but includes a key-way on the shaft for secure coupling. For a complete servo system, it pairs perfectly with the Delta ASD-B2-0421-B drive (220V AC single-phase input). All necessary connectors for CN1, CN2, and power terminals are included, though cables are sold separately.
