Overview
The Transtecno CMG series is a range of helical in-line gearmotors designed around modularity and reliability. Built with die-cast aluminium housings across all five sizes (00 through to 04), these units deliver quiet, efficient power transmission in a compact and lightweight package.
What makes the CMG range particularly popular across Australian industries is the ability to configure each gearbox to suit the job. Starting from a base unit, you can add foot mounts, output flanges, or a combination of both. This modular approach means you are not locked into a single configuration, and replacement or upgrades become straightforward.
The helical gears themselves are ground hardened, which contributes to smooth, low noise operation and a long working life. Every unit ships pre-filled with synthetic oil (viscosity grade 320), so there is no scheduled lubrication to worry about. You can install these gearmotors in any mounting position without additional maintenance requirements.
Poultry and Agricultural Feeding Systems
Sizes 00, 01, 02 and 03 of the CMG range are widely used in the Australian poultry sector. These gearmotors are a proven solution for driving both chain feeder and screw feeder systems, as well as moving feed troughs across sheds.
In a typical chain feeder application, the gearmotor consists of a CMG helical gearbox paired with a three phase electric motor. This combination provides the consistent, controlled torque needed to move feed chains reliably over long runs. The low output speeds and solid torque characteristics of the two and three stage helical reduction make the CMG well suited to this kind of continuous duty work.
For screw feeder systems, the in-line shaft arrangement of the CMG keeps the drive compact and aligned with the auger, reducing the need for additional couplings or adapters. The result is a cleaner installation that is easier to maintain and less prone to alignment issues.
Key Features
The CMG range stands out for several practical reasons. The aluminium construction keeps the overall weight down, which matters when you are mounting gearmotors on elevated feed lines or framework that was not designed for heavy equipment. At the same time, the cast iron feet and output flanges provide the structural strength needed at the mounting and load bearing points.
Ground hardened helical gears are quieter and more efficient than standard cut gears. In a poultry shed environment where noise can affect livestock, this is a genuine benefit rather than a technical footnote.
Permanent synthetic lubrication across all sizes means these gearmotors are sealed for life. There is no oil level to check, no scheduled changes, and no risk of contamination from opened fill plugs. For operations running dozens of gearmotors across multiple sheds, this alone can save meaningful time and labour over the course of a year.
The optional input flexible coupling is worth considering in applications where vibration or minor misalignment between the motor and driven equipment could cause premature wear.
Common Applications
Beyond poultry, the CMG helical in-line gearmotor suits a broad range of industrial and agricultural applications. These include conveyor drives, packaging machinery, food processing equipment, mixing systems, and general material handling. The modular mounting system and wide selection of gear ratios make it straightforward to match a CMG unit to the requirements of most low to medium power drive applications.
Australian businesses across agriculture, food production, manufacturing, and logistics rely on these gearmotors for equipment that needs to run day in, day out without fuss.
Selection Considerations
Choosing the right CMG gearmotor comes down to matching the output speed, torque and motor power to your application. With ratios available from 3.66:1 all the way through to 449:1 across two and three stage configurations, there is considerable flexibility in the range.
Gearbox size selection depends on the torque and radial load demands of your equipment. Size 00 suits lighter duty drives, while size 04 handles output torques up to 655 Nm and radial loads up to 8000 N. Your motor choice (single phase, three phase, or high efficiency IE2/IE3) will depend on your power supply and any energy efficiency requirements.
Mounting configuration is another key decision. The U version is the base unit without feet or output flange. The H version adds foot mounting, the F version adds an output flange, and the H/F version gives you both. Each option has multiple dimensional variants, so it pays to confirm the physical envelope and bolt pattern before ordering.
The service factor for your application should also be considered. For continuous or high duty cycle operations, it is best to speak with our team to ensure the selected gearmotor has adequate capacity for the job.
