Small Geared Motors/Gear Head-Induction Motors/Reversible Motors

MISUMI

- Gear Head for Induction Motors and Reversible Motors from MISUMI.
- There are 2 types of gear heads available, PACMGX for motor output40 W or lower, PACMGZ for motor output 60W or higher).
- The rotational speeds shown are based on synchronous operation speeds. Generally, the actual speeds may be 2 ~ 20% less than indicated value depending on load conditions.
- Wide Variety of Products Gearheads are available with 22 different gear ratios from 1:3 to 1:180.

Small Geared Motors and Gearheads, Induction / Reversible Motors

Induction motors and gear heads. Choose the motor type, phase, frame size A, output (W), voltage (V), frequency and gear ratio; electrical data and mounting dimensions are listed per model.

PACMS is a single-phase induction motor with a continuous rating and 4P construction.
