Hollow-shaft Speed Changers

and Reducers

 

These are low-output hollow-shaft geared motors for motor outputs of 60 W and 90 W.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. The motor/speed reducers use an IP-54 structure, so they boast excellent environmental resistance.

RW MINI 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.

RWM Models

These models add a belt-type stepless speed changer to an RWM hollow-shaft geared motor. They are about 30% lighter and 20% smaller than our previous belt-type stepless speed changer (0.4-kW model).They can also operate at high torque while at low speeds (compared to the 0.4-kW model), not a traditional strength of inverters.

RWP Models

These are hollow-shaft geared motors with brakes that use spring-actuated brake motors for the motor part of the RWM.The brake is a spring-actuated type that brakes or holds instantly when power is cut off, with a release lever to manually release the brake. A small power supply is built into the terminal box, so wiring and handling are easy
