Helical Geared Motors
Efficient in-line drives
Helical geared motors provide efficient in-line speed reduction for conveyors, mixers, agitators and continuous process drives. NPE sizes the ratio and service factor for the duty.
Helical gearing gives high efficiency and quiet running, making it the default choice where the motor and driven shaft are in line.
