RV40 turbine reducer with 400W servo motor size


The standard flange for the 400W servo motor is 60B5, which can be directly connected to the customized 60B5 servo input flange of RV40 without the need for additional processing of adapter plates. The installation has high coaxiality, avoiding vibration and accuracy loss caused by eccentricity.

Key points for avoiding pitfalls in the selection of RV40 servo turbine reduction motor

It is prohibited to directly pair the standard RV40 with the servo motor, otherwise excessive backlash may lead to loss of positioning accuracy

It is necessary to use a bellows coupling to connect the servo and reducer, completely eliminate the transmission gap, and ensure the synchronization of motion

The recommended speed ratio is between 10-60, which can accurately reduce the rated speed of the 400W servo from 3000rpm to the practical output range of 50-300rpm
