The GL30 KV290 without encoder is lighter (41 g against 90 g), narrower (34.5 mm against 41.8 mm) and shallower (15.7 mm against 21 mm), and turns faster at the output (1990 RPM against 815 RPM). The GL35 KV100 without encoder has more continuous torque (0.15 N·m against 0.08 N·m), more peak torque (0.46 N·m against 0.28 N·m) and a higher torque constant (0.115 N·m/A against 0.038 N·m/A), and draws less current at its rating (1.3 A against 2.13 A).
The GL30 KV290 without encoder is US$57 and the GL35 KV100 without encoder is US$62. That is US$712.50 per rated N·m for the GL30 KV290 without encoder and US$413.33 per rated N·m for the GL35 KV100 without encoder.
