The GM series (High Precision Compact Series) is an extremely accurate high power pancake motor range with possible high ambient temperature (150°C, 302°F) operation, for high performance industrial applications. The range is available in 9cm, 12cm and 16cm armature diameter sizes, with standard and high power AlNiCo magnet option.

GM series motors also have an ironless ultra-flat construction and feature zero cogging, resulting in ultra low velocity ripple.

Additionally, through a special build scheme, every motor in the GM 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 series has been popular across high-end servo applications requiring a compact motor with perfect control.

FEATURES & CUSTOM CONFIGURATIONS
GM series servo motors are designed to be ultra-compact and utilize axial flux, DC brushed, and permanent magnet technologies. They are equipped with a printed armature and make use of AlNiCo Magnet Technology. These motors come in three different sizes and are offered across four ranges.

Customization is possible to suit various needs, with options available for the magnet material, tachometer, encoder, gearbox, and shaft.
