GS series

GSK’s GS range addresses AC servo and spindle applications. Its official page separates compatible motor power ranges and lists several three-phase supply variants, which must be matched to the selected drive.

Motor ranges

0.5–30 kW PMSM servo; 1.5–45 kW asynchronous spindle motors

Supply variants

Three-phase 220 V, 380 V or 440 V

Feedback

Second position-feedback input is described

Braking

External braking resistor with an internal braking transistor is described at family level

Questions for this product range

1. Is the application a feed servo, spindle motor or built-in spindle?
2. Identify the required second-feedback device and interface.
3. Provide the exact drive current rating and braking-resistor calculation.
