Standalone gearheads from Maxon Motor Australia

Supplier News

Maxon Motor Australia  presents a range of gearheads to meet the demand for standalone units from the market.

Maxon Motor already manufactures ceramic planetary gearheads for use in conjunction with DC brushed and brushless motors (gear motors), and has traditionally supplied these precision planetary units only as gearmotor combinations.

The new demand for standalone units is due to the increased efficiency and improved wear characteristics of Maxon Motor gear units. These standalone gearheads find use in applications where a DC motor is being used as a generator or a brushless DC motor is being used as an alternator.

The 22mm and 32mm ceramic planetary gearheads are now available in double ended standalone units. The 22mm gearheads feature a 4mm hardened stainless steel shaft at both the input and output, with the shaft being configured with and without a flat. The 32mm planetary gearheads incorporate a 6mm hardened stainless steel shaft at both the input and output with shaft modifications done on request.

Reduction ratios on the smaller 22mm gearheads range from 3.8:1 through to 4592:1 while the reduction range on the 32mm unit is higher at 3.7:1 through to 6285:1.

New energy experiments are requiring particular output power levels with extremely high or low input speeds. This requirement combined with space and weight restrictions has often been unachievable with commercially available components, given that gearing is often required and traditional planetary gearheads are not designed to be back driven.

However, new motor technology achieving levels over 700w from 32mm and a mass of only 730g or even 240w/ 230g from 22mm can now be used as generators with a wide range of input speeds by simply turning the gearhead around.

The ceramic planetary gearheads have high natural efficiencies and the motors are zero cogging with no electromagnetic detent, resulting in some of the smallest generator and alternator units with low mass, low mechanical friction, low inertia and high efficiency.
