Features of PDC 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.

Options of PDC Models

Index Handle SD-Equipped

ハModels equipped with an index handle to allow easier reading of handle turns. When the handle is rotated once, the little hand moves one gradation. This makes it possible to minutely read handle turns.

Units with Remote Controllers

These are flexible-shaft remote controllers that can be used with belttype stepless speed changer units to allow remote operation. They are available as RFA type controllers, which have a flexible shaft in the motor shaft axial direction, or as RFB type controllers, where the flexible shaft is perpendicular to the motor shaft.

RFB-types allow you to choose the flexible shaft direction.

Items Checked for Design Purposes

Units with a remote controller have the following configuration with regard to standard units.

・Motor-side speed changer for remote controller AK (RF)
・Remote Controllers RF
・Flexible shaft
・Index handle (Option)

Ensure that the curve of flexible shafts is within a radius of R300 mm. If flexible shafts cannot be routed easily, place guides, etc. on the flexible shafts.
Standard flexible shaft lengths are 1000, 1600, 2500 mm. Consult Miki Pulley regarding lengths that are also available other than standard length.

Motor Side Speed Changer AK (RF) for Remote Controller RF

These are dedicated motor side speed changers that allow the speed to be changed with an RF remote controller.

Handle Mounting Square Hole for Adjustment during Stop TH

Fine adjustments and positioning can be performed easily by using the handle inserted to this hole during machine stop.
Mount the adjustment handle for adjustment during stop TH to the square hole bushing of the PE model speed change pulley to perform fine adjustments and positioning.
Please order an adjustment handle for adjustment during stop (TH-125- □ ) separately.
