The YASKAWA SERVO MOTORS BREAK 400W SGM7J-04A7C6E is a next-generation AC servo motor from the renowned Σ-7 family, engineered for applications requiring precise speed, torque, and position control. This 400W model incorporates a fail-safe 24VDC brake, ensuring safe holding in vertical or high-inertia loads. With its low-inertia rotor, the SGM7J-04A7C6E delivers exceptional dynamic response and minimal settling time, making it ideal for pick-and-place, packaging, and robotic systems. The 20-bit serial encoder provides absolute feedback resolution, eliminating the need for homing cycles in many setups. Built with Yaskawa’s advanced magnetic design, it achieves high efficiency and low cogging torque, even at low speeds. The motor is fully compatible with SGD7S series servo drives, enabling advanced vibration suppression and auto-tuning features.
