Features of Variable Worm Geared Motor

Quick and simple. By rotating control knob in running condition only
Up to 1.7 times input speed without necessity of speed increasing gear
Overall 85% throughout full speed range ideally used for constant power transmission
Quite stable with uniform load and within 0.25% with Max. Load
Drive is highly reliable with long life as load is equally distributed on number of conical Rollers

Features of Double Worm Geared Motor

Quite stable with uniform load and within 0.25% with Max. Load
High Power Transmission capacity with small dimensions
Quick and simple. By rotating control knob in running condition only
Up to 1.7 times input speed without necessity of speed increasing gear
Ideal for hazardous zones and practically maintenance free. Only ensure proper lubrication

Features of Mechanical Variable Speed Drives

Drive is highly reliable with long life as load is equally distributed on number of conical Rollers, which are hardened, and ground to close tolerance
Quite stable with uniform load and within 0.25% with Max. Load
Overall 85% throughout full speed range ideally used for constant power transmission applications in all types of Industries
When speed is reduced, Variators can replace Gear Boxes

Features of Variable Helical Geared Motor

No moving parts like Chins, Belts, etc. Drive is through rolling action of PRECISION ROLLERS, which are continuously lubricated. All components are well balanced
Clockwise/Anti Clockwise depending upon Input shaft rotation, viz. Anti Clockwise/Clockwise respectively
Practically maintenance free. Only ensure proper lubrication
Speed Variations - 12:1 to 3:1 depending upon selection
