Extended Introduction of the Yaskawa Servo Motor Model SGMGH-20A2B6C

The Yaskawa SGMGH-20A2B6C is a high-performance servo motor from the SGMGH series, designed for demanding industrial automation applications. It delivers a rated output power of 2.0 kW and operates at a rated speed of 1000 r/min, making it suitable for applications requiring stable torque output at lower speeds. The motor is powered by a three-phase AC 200V power supply, ensuring compatibility with standard industrial voltage systems.

Equipped with a 17-bit absolute serial encoder, the motor provides high-resolution position feedback, enabling precise motion control. The B design sequence indicates an optimized version with enhanced reliability and performance characteristics. The motor shaft features a straight shaft with a key and threaded hole, allowing secure mechanical coupling to driven loads.

This model is offered with an optional DC24V brake, which is particularly useful for applications requiring holding torque when the motor is powered off, such as vertical axis or safety-critical systems. The motor is part of the high-speed feed series, designed to maintain high-speed operation even under no-load conditions, making it ideal for rapid positioning and high-throughput machinery.

A key design advantage is the complete separation of the main circuit and control circuit power supplies. This separation allows maintenance personnel to shut off only the main circuit power in the event of an alarm, while keeping the control circuit active for diagnostics and status monitoring, significantly simplifying troubleshooting and reducing downtime.

The motor features a built-in parameter setting unit, enabling direct parameter input from the servo drive itself. This integrated approach reduces wiring complexity and saves installation time. The use of a serial encoder reduces the number of encoder wiring lines by half compared to previous models, further simplifying cable management and improving system reliability.

Additionally, the servo motor supports multi-function control via parameter switching, allowing users to seamlessly switch between torque control, position control, and speed control modes. This flexibility makes the SGMGH-20A2B6C suitable for a wide range of applications, including CNC machines, packaging equipment, robotics, and material handling systems, where versatile and precise motion control is essential.
