CHPC 80 + CHM 075 Worm Gearbox with Pre-Stage Module (ratios 90–150:1)
CHPC 80 pre-stage module (ratio 3:1, IEC 80 B5 motor flange) coupled to a CHM 075 worm gearbox — total ratios 90–150:1 in one compact unit, for the slow output speeds a single worm stage cannot reach. Aluminium CHM housing, hollow output shaft with 28 mm bore, keyed; optional output flanges as the CHM 075. The dimension sheet gives the combined unit (CHPC/CHM 80+075); the gearbox connected to the pre-stage has the pre-stage's Z1 input dimension. Supplied for the B3 mounting position — tell us if you need a different orientation (see the mounting-position drawing). Filled for life with synthetic oil — no oil changes, no maintenance.
Supplied without motor. Fits an IEC 80 B5 motor (19 mm shaft).
How to pick from the table: with a standard 4-pole motor (1400 r/min) the total ratio sets the output speed; P1 is the motor power the catalogue pairs with the row and the output torque is at that power. The catalogue notes the installed power is sometimes more than the gear needs — always check the output torque against your load, and ask us if in doubt.

Product Information
Motor pole count
All table figures assume a 4-pole motor (1400 r/min input) — the standard choice for most applications. A 2-pole motor (2800 r/min) doubles the output speed and a 6-pole motor (900 r/min) reduces it, and the power and torque ratings change with them — if you're running anything other than 4-pole, contact us and we'll size it for you.
Reading the table
Each row is one total ratio (pre-stage × worm stage): output speed at 1400 r/min in, the catalogue's motor power P1 for that row and the output torque at that power. Specify the mounting position of the pre-stage relative to the gearbox when ordering (supplied for universal assembly when the module comes on its own).
