The Yaskawa SGMGH-20ACA2B servomotor is a high-performance model from the SGMGH series, designed for demanding industrial automation applications. It operates at a rated speed of 1500 revolutions per minute and delivers a power output of 1.8 kW, making it suitable for applications requiring precise motion control and reliable torque output. The motor is powered by a three-phase AC 200V supply. It features a 17-bit serial absolute encoder, which offers high-resolution position feedback for enhanced accuracy and smooth operation at both low and high speeds. The design order is "A," and the motor shaft is configured as a straight shaft without a keyway, which simplifies installation in certain mechanical setups. An optional DC90V brake is integrated, providing holding torque when the motor is not powered, ensuring safety and stability in vertical or gravity-loaded applications.

This motor belongs to the high-speed feed series, designed for scenarios where high-speed operation is required even under no-load conditions. A key feature of the SGMGH series is the complete separation of the main circuit and control circuit power supplies. This allows the main circuit power to be shut off independently during an alarm, facilitating easier maintenance and troubleshooting without disrupting the control logic. The motor incorporates a built-in parameter setting unit, enabling direct input of parameters from the servo drive body. This design reduces wiring complexity and simplifies system configuration.

The use of a serial encoder reduces the number of encoder wiring lines by half compared to previous models, contributing to easier installation and improved noise immunity. The servo motor supports multi-function control, allowing users to switch between torque, position, and speed control modes simply by changing parameters. This versatility makes it highly adaptable to a wide range of motion control tasks, from simple positioning to complex dynamic operations. Overall, the SGMGH-20ACA2B combines high reliability, ease of maintenance, and flexible control capabilities, making it an ideal choice for advanced servo systems.
