Specification

The YASKAWA SERVO MOTOR 400W SGMJV-04A3E6S is a robust and versatile AC servo motor from the Sigma-5 series, engineered for demanding industrial automation tasks requiring precise speed, torque, and position control. This 400-watt model features a 20-bit incremental encoder (standard for this variant) that delivers 1,048,576 pulses per revolution, enabling fine resolution and minimal ripple. The motor operates on a 200V AC input and is compatible with Yaskawa’s SGDV or SGD7S drive series. Its compact 60 mm square flange and 115 mm body length make it suitable for space-constrained installations, while the IP67-rated connectors ensure durability in harsh environments. Below are the detailed technical specifications derived from the official Yaskawa documentation.
