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.
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.
