The GL40Ⅱ KV82.5 is lighter (112 g against 230 g) and narrower (46.1 mm against 69 mm), and turns faster at the output (697 RPM against 310 RPM). The GL60 KV25 without encoder has more continuous torque (0.6 N·m against 0.25 N·m), more peak torque (1.75 N·m against 0.68 N·m) and a higher torque constant (0.450 N·m/A against 0.11 N·m/A), draws less current at its rating (1.35 A against 1.88 A), and is shallower (22.3 mm against 33.5 mm).
The GL40Ⅱ KV82.5 is US$150 and the GL60 KV25 without encoder is US$122. That is US$600.00 per rated N·m for the GL40Ⅱ KV82.5 and US$203.33 per rated N·m for the GL60 KV25 without encoder.
