The GN series (High Precision Slim Series) is an extremely accurate high power motor range but is one third the axial thickness of the GM range, making it one of the flattest motors available.

The additional benefits of using NdFeB (Rare Earth) magnets are that it is possible for the motor to operate in low ambient temperature (-20C, -4F), for high performance industrial applications.

The range is available in 9cm, 12cm and 16cm armature diameter sizes. Additionally, through our special build scheme, every motor in the GN series is available as a low resistance, i.e. parallel ‘winding’ (designated LR) motor perfectly suited for low voltage, battery or higher speed applications.

Historically this motor has been used in extreme high-end servo applications requiring an ultra-compact motor with perfect control. The GN series is often a straight drop-in replacement for older N-series and KN-series servo motors from PMI Kollmorgen.

FEATURES & CUSTOM CONFIGURATIONS
