AC Gear Motors - Brother Gearmotors

.

High Power Brother GearmotorsHigh Torque Brother Gearmotors - 1/2 HP to 3 HP

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.

ie3 Efficiency Motors

ie3 Premium Efficiency Gear Motors (1 - 3 HP Motors) Saves Significant Operating Costs

The new ie3 premium efficiency gear motors cost less to operate and demonstrate clear benefits when running for long periods of time (when compared to ie1 standard efficiency gear motors).

Benefits of using Premium Efficiency ie3 motor when compared to standard ie3 motor:
  • Helps improve overall plant efficiency by reducing energy costs
  • Helps increase ROI and long term savings
  • Minimizes maintenance and helps improve overall operations
  • Helps increase flexibility due to the wide speed range (stock reduction)
  • Produces less noise and runs cooler with less mechanical stresses
  • Environmentally friendly-RoHS compliant

Compare ie1 vs. ie3 Motor Efficiency

ie3 Premium Efficiency Motors

High Efficiency Gear Motors

ie3 Gearbox Efficiency

High efficiency gear motors feature Hypoid gearing technology that can maintain efficiency above 85% throughout the motor's wide speed range. Compared to commonly used worm gears' lower efficiency, this can result in massive energy savings. Lower cost to operate - applications running for long periods will demonstrate clear benefits.

The ie3 gear motors have a wide speed range that does not suffer in efficiency from the motor or gearbox. These gear motors can be mounted in any direction because they are sealed for life with grease.

Electrocoat Paint
The ie3 gear motors also feature an acrylic Electrocoat paint that provides total coverage of the gearmotor. Similar to how the frames of cars are painted, each individual outer facing part is completely dipped in electrically charged paint. This offers complete coverage of the outer body which helps prevent cleaners from penetrating and chipping paint. This acrylic paint also has a higher level of hardness which will avoid scratches and scrapes from chipping the paint. Lastly, the paint is FDA approved to have incidental food contact specifications.

IP65 Type
The ie3 gear motors have been made to withstand harsh environments. Available IP-65 ratings allow these gearmotors to be cleaned with cleansers for sanitation without affecting the motors' performance.

Comparison

This is a general approximation based on standard worm gear efficiency. Cost savings are approximate. Actual savings may vary.
Comparative information obtained from competitor's website.

High Torque AC Gear Motors

These high torque AC gear motors offer superior efficiency by using Helical and Hypoid gears making it possible to replace spur and worm gearbox/motor combinations with smaller HP AC gear motors and actually receive greater torque at the driven shaft. With smaller motor HP required less electrical current is needed, resulting in lower energy costs.

  • Helps protect against pressure jets of water
  • Helps protect against dust and harsh environments
  • Terminal Boxes are specially designed, sealed and gasketed. Complete with stainless steel IP65 cord grip.
IP65 Type Brother Gear Motors

Brake Types Available

The brake system for these AC gear motors uses vibration damping sheet steel for the armature, which dramatically reduces noise associated with the brake.

Brother Helical Gears

High Torque Brother Gearmotor Helical Gearing

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

Brother G3 Helical Gear MotorLightweight 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.

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 Gear 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.

Brother Hypoid Gear Efficiency

Input Speed - 1800 RPM

Worm - Oil Lubrication

The graph above shows actual measured efficiency, 1/2 HP to 3 HP. Because of the high efficiency of the Brother Gearmotor Hypoid/Helical combination there is no self-locking in the back drive direction.

Right-Angle AC Gear Motor - Brother Gearmotors Hypoid Gearing (H2 Series)

Brother H2 Hypoid 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.

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.

Hypoid Gearing

Hypoid Gears are made of chromium molybdenum steel that has undergone precision caronitriding. 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.

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.
