1.Features

Right-Angle Shaft & High Reduction Ratio
The croise motor, using a worm gear, delivers space savings in your equipment layout with a right-angle shaft. The HCMA series provides a maximum reduction ratio of up to 1/300 with the combination of a 1st helical gear and a 2nd worm gear.
Lightweight & Compact
Using an aluminum frame motor in all capacity ranges makes the HCMA series light in weight. This series is also compact in height by reducing the offset volume of output and input shafts of the worm gear.
Quiet Operation
With the use of a worm gear, provides very smooth and quiet operations compared to other gear mechanisms. Also, the silent-type brake eliminates annoying metallic sounds during suction.
Shock Resistance
The worm gear has a stronger tooth root than other gear mechanisms, providing superior shock resistance.
High Stopping Accuracy
Excellent positioning accuracy can be expected due to less backlash compared to other gear mechanisms.
