The 22 mm and 32 mm right angle gearheads are available in either a 4:1 or 31:1 ratio, which may be mounted directly onto many of maxon's brushed/brushless motors or stacked on different ratios of maxon's GP22 and GP32 planetary gearheads. This results in a wide range of achievable gear reductions. The motor and gearhead combinations are suited for a variety of applications particularly where an output shaft perpendicular to the motor axis is desired.
