The Yaskawa SGMGH-30DCA6H-OY is a high-performance AC brushless servo motor belonging to the renowned Sigma II series. It is specifically engineered for high-inertia applications such as machine tool feed axes, packaging machinery, and material handling systems. With a power rating of 2.9kW (2900W), it provides the necessary torque density to handle heavy loads with rapid acceleration and deceleration cycles.
Operating on a 400V input, this motor is designed for global industrial standards. The "6H" in the model code indicates the presence of a 24VDC electromagnetic brake, which is essential for vertical axis applications to prevent load dropping during power loss or emergency stops. The brake system is seamlessly integrated into the motor housing, maintaining a compact form factor while providing fail-safe operation.

Precision control is achieved through the integrated serial encoder, which provides high-resolution position feedback to the servo drive. This ensures smooth rotation at low speeds and exceptional positioning accuracy. The motor's thermal characteristics are managed through high-grade insulation materials, allowing it to operate efficiently within a wide ambient temperature range without compromising its performance or service life.
The SGMGH-30DCA6H-OY features an IP67-rated enclosure (excluding the shaft opening), providing excellent protection against dust and moisture ingress. This makes it suitable for use in environments where coolant or oil mist may be present. The robust mechanical construction and high-quality bearings ensure minimal vibration and noise, contributing to the overall stability of the automation system.
