Note: Pole Count for GM115 is 12
Thermal Resistance for GM115 is 0.95 oC/W
Stator winding thermal resistance (winding to ambient) is for the unit, mounted to a 254mm x 254mm x 12.7mm (10in x 10in x 0.5in) aluminum plate.
(1) These specifications refer to the output of the GM assembly.
When programming a digital amplifier for use with a GM assembly, these specifications must be adjusted by the ratio to create actual motor performance
(2) Inertia = Motor Rotor + Gear Selection. External Inertia must be divided by the square of the ratio.
