en.Wedoany.com Reported - FAULHABER has launched the GPT gearhead series, designed to meet key market demands for flexibility, power density, and cost. These gearheads can be paired with a variety of motors from the company's standard product portfolio, including the flat BXT brushless motors and other brushless DC drives. Their design also supports compatibility with DC drives from the GXR/SXR series, enabling a compact combination of encoder, drive, and gearhead with matching diameters and no additional connecting elements.
The GPT gear series is specifically designed for applications requiring high torque. Each stage can contain up to six planet gears, a design that enhances torque capacity within a compact structure while reducing overall length. The GPT planetary gears are manufactured from hardened stainless steel, with connections supported by continuous welding to facilitate force transmission. The gearbox diameters range from 14 to 42 mm, making them shorter than other models in the same diameter range. Their design can handle both constant loads and sudden load changes; for example, the 42 GPT series can achieve intermittent torque of up to 25 Nm.
Depending on the version, these gearheads support continuous torque from 0.6 to 18 Nm and speeds up to 24,000 rpm. Reduction ratios range from 3:1 to 1437:1, allowing drive configuration according to different application requirements. Component matching, lubricant selection, and a range of output bearing options also contribute to overall operational performance.
The low-noise versions of the GPT series are developed for applications requiring reduced sound levels, such as systems used near personnel or machines equipped with multiple motors. By using a plastic input gear stage, the 22 GPT LN and 32 GPT LN models can reduce noise levels by up to 10 dB compared to standard versions. These models can still handle occasional peak torque of up to 4 Nm and 12 Nm, respectively. With an operating temperature range of -30 to +110 degrees Celsius, they are designed to maintain efficiency under frequent or sudden load changes while balancing performance and cost.
The HT models are suitable for working conditions demanding greater gearhead robustness. Their geometry is adjusted for higher loads, improved dynamic response, and enhanced performance. These models are available in three-stage and four-stage versions with various reduction ratios, an operating temperature range of -30 to +120 degrees Celsius, and are designed to withstand sudden load changes and emergency stops over a long service life. Depending on the model, gear backlash is 0.8° or 0.6°, which aids in achieving repeatable positioning across various applications.
