Features of RWM Models

These are hollow-shaft geared motors for motor outputs of 0.2 kW to 1.5 kW (4-pole).They use hollow-shaft speed reducers and do not require transmission components such as couplings, chains, or sprockets, so virtually nothing rotating is exposed to the outside, and high safety is assured without use of a safety cover. And since special long-life oil is used in the speed reducer, oil changes are unnecessary. The sealed construction also allows flexibility in mounting on top, bottom, left or right.
