Description
The SGM7G is a rotary Servo-motor from Yaskawa’s flagship Sigma 7 range of servo systems. SGM7Gs specialise in medium inertia, high torque, high or low speed applications and are available in sizes ranging from 450W to 15kW. This version comes fitted with an optional 24VDC holding brake.
When designing the Sigma 7 range Yaskawa focused on three main development goals:
- Fast and easy to understand set-up / commissioning – This is achieved with the help of presets in the amplifier software which allows for the system to be commissioned without the need to learn the full expansive range of parameters beforehand.
- Outstanding reliability – With over 12 million servo systems already in the field Yaskawa’s Sigma drives are tried and tested to work no matter what is thrown at them. The latest iteration of Sigma servo systems come with a host of new improvements to help increase uptime which reducing maintenance and servicing costs.
- Increased efficiency and production output – Sigma 7 motors come with a more optimised magnetic circuit which helps improve motor efficiency and reduces the thermal buildup meaning that additional cooling is unnecessary.
