Brother Gearmotors Single-Phase AC Motors & Gear Motors

High Torque Single-Phase Brother Gear Motors

Brother Gearmotors Single-Phase AC Motors & Gear Motors

These AC gear motors feature superior efficiency from hypoid or helical gears while offering greater torque output thereby allowing for smaller motors and greater energy saving.

The gears in these AC gear motors are high strength, maintenance free and can be mounted in any direction with their slip fit "O" ring design. High reduction ratios, flange mount or foot mount types, right angle or hollow shaft right angle types available.

  • 400 W (1/2 HP)
  • Parallel Shaft (Foot Mount or Flange Mount), Right-Angle Hollow Shaft and Right Angle Solid Shaft Gear Types
  • Single-Phase 115, 220 and 230 VAC

Parallel Shaft AC Gear Motor - Brother Gearmotors Helical Gearing (G3 Series)

Parallel Shaft Foot Mount Gear

Lightweight and Compact

Die cast aluminum gear housings and motors make these AC gear motors and reducers light in weight, allowing engineers to design more economical mounting provisions.

Longer Life

Compared to a spur gear of approximately the same pitch diameter, Helical gears can transfer high loads at greater speeds. This is due to the gradual engagement of the teeth and smooth transfer of the load.

Helical Gears

Maintenance Free

High-quality synthetic grease is used in all gearboxes. They are filled at the factory and do not require maintenance filling or level checks. This saves valuable time at set up and eliminates concern for costly oil disposal required by the EPA.

High Durability Finish

Electrocoat paint is standard for these AC gear motors and provides higher durability and superior resistance vs. traditional painting or powder coat finishes and can also be considered for harsher environments.

Mount in Any Direction

These gearboxes are sealed with machine "slip" fit "O" rings and double lip spring shaft seals on both the motor and input shaft and output shaft driver. Thus, the gear motors can be mounted in any conceivable direction without concern for the position of a breather plug.

Spur vs. Helical Gear

These motors feature Helical Gears made of chromium molybdenum steel that has undergone precision carbonitriding. These Helical Gears outperform common spur gears.

Right-Angle Hollow Shaft AC Gear Motor - Brother Gearmotors Hypoid / Helical Gearing (F3 Series)

Right-Angle Hollow Shaft Gear Motor

More Efficient / Longer Lasting

Hypoid gearing is up to 80% more efficient than worm gears. The all steel Hypoid/Helical combination had much better wear properties than softer bronze worm gearing and last longer and run cooler than worm gears.

Hypoid GearHypoid Gear Efficiency

High Reductions / Small Size

Gear reductions up to 1500:1 are available in most sizes. Hypoid gearing makes the high reduction significantly more compact and lightweight compared to worm/worm and helical/worm designs.

Hypoid Gearing

Hypoid Gears are made of chromium molybdenum steel that has undergone precision carbonitriding. The superior efficiency, gear materials and heat treatment allows engineers to design-in the most compact gearmotor per output torque. These unique right-angle type gear motors have much higher power transmission efficiency than conventional worm gears. Growing demand is due to its COMPACTNESS, HIGH EFFICIENCY, and superior wear life, which meet the latest primary requirements for industrial applications.

Right-Angle Solid Shaft Gear Motor

Longer Life

Hypoid gear motors and reducers use hardened steel gears throughout. This give Hypoid gearing far superior wear life compared to worm gears which use softer bronze on the output gear.

Hypoid Gear Efficiency

High Reductions / Small Size

Gear reductions up to 1200:1 are available in most sizes. Hypoid gearing makes the high reduction significantly more compact and lightweight compared to worm/worm and helical/worm designs.
