These models combine ANS model speed changers with motors and worm reducers. The appropriate output RPM is obtained using the speed change mechanism.There is a full line-up of shapes, including horizontal and vertical, so installations are easy to design

ANW NHN/PMN Models

Rotate the handle of the speed changer on the motor side to change the width of the speed-change pulley.When you change the pitch of the speed-change belt hanging from it, the pitch diameter of the speed-change pulley on the machinery side tracks it, for a belt-type stepless speed changer that can freely change the rotation speed. Instead of the coil spring that traditionally tracks the machinery-side pulley, the ANS models use a constant-pressure load disc spring to track the pitch diameter changes of the motor-side pulley. Use of a disc spring increases transmission efficiency and enables stable speed-change operation.

Belt-type Stepless Speed

Changer Units

These models combine ANS model speed changers with motors and worm reducers. The appropriate output RPM is obtained using the speed change mechanism.There is a full line-up of shapes, including top and bottom facing output shafts, so installations are easy to design.

ANW NKN Models

These models combine ANS model speed changers with motors and co-axial reducers. The appropriate output RPM is obtained using the speed change mechanism.Co-axial reducers are not constructed to require oil, making them maintenance-free to provide design flexibility.

ANG GDN Models

These are models that combine an ANS model speed changer with an electromagnetic clutch/brake, motor, and worm reducer. They are a compact design that incorporates an electromagnetic clutch in the driven speed-change pulley and an electromagnetic brake on the worm reducer input shaft.Combining with a worm reducer enables the optimum output RPM, while the electromagnetic clutch and brake enable simple start/stop, positioning, inching, and intermittent operation.

ACW Models

These are models that incorporate an electromagnetic clutch/brake unit and a motor into an ANS model speed changer. This enables the optimum output RPM, while the electromagnetic clutch and brake enable easy and high frequency start/stop, positioning, inching, and intermittent operation.

ANB Models

Rotate the handle of the speed changer on the motor side to change the width of the speed-change pulley.When you change the pitch diameter of the speed-change belt hanging from it, the pitch diameter of the speed-change pulley on the machinery side tracks it, for a belt-type stepless speed changer that can freely change the rotation speed.

PDS Models

These are stepless speed changers that incorporate a motor and a driven shaft into a PDS model speed changer on a bed.They are very simple speed changer units. They are perfect for customers who design creatively.

PDC Models

These are stepless speed changers that incorporate a motor and a worm reducer into a PDS model speed changer on a bed.The PDG-BSN is the standard model, but a brake motor can be used for the motor, the output shaft of the speed reducer can be faced upwards, a two-stage worm reducer can be used, or a variety of other changes can be made.

PDG PSN Models

The AH series are boxed units that can be combined, as necessary, with transmission equipment such as electromagnetic clutches/brakes and motors around a belt-type stepless speed changer.The AHS models are intermediate speed-changer units that can be mounted between machine and machine or between motor and machine. Electromagnetic clutches/brakes can be built into the standard AHS-A model as tracking functions (for the AHS-B model), enabling complex control such as frequent start/stop and inching.

AHS Models

The AH series are boxed units that can be combined, as necessary, with transmission equipment such as electromagnetic clutches/brakes and motors around a belt-type stepless speed changer.These models integrate an AHM model with a motor and speed changer. Electromagnetic clutches/brakes can be built into the standard AHM-A model as tracking functions (for the AHM-B model), enabling complex control such as frequent start/stop and inching.
