New pure metal GPT gearheads from FAULHABER MICROMO feature performance values comparable to more expensive technologies on the market like ceramic components. The gearheads are available in diameters of 22, 32 and 42 mm. Compared to predecessor models, the continuous input speed was more than doubled above 10,000 rpm, and can support input speeds up […]
Gears + Gearing
How do cycloidal gears work and where are they used?
One way to classify gears is by the profile of the gear teeth: involute, cycloidal, or trochoidal. (Note that trochoidal gears are used primarily in pumps.) The majority of gears used in motion control applications — including spur, helical, and bevel designs — are involute gears. However, cycloidal gears are a good choice for motion control […]
Pedal electric cycles (pedelecs) employ FAULHABER electric motors
In many parts of the world, bicycles are central to the culture — both for recreation and practical transportation for everyday tasks such as shopping or commuting to and from work. Efforts to reduce CO2 emissions, concerns about climate change, and rising fossil-fuel costs in many areas (along with congested roadways) have only spurred more […]
New DieQua PGW Series hollow-bore-output planetary reducers
Now DieQua Corp. (solution-based supplier of gear drives) sells PGW Series reducers in variations that are particularly suitable for belt and leadscrew-driven axes. The manufacturer works with engineers to find optimal products from a wide range of available gearbox technologies for design requirements. DieQua’s PGW planetary reducers are: Low-backlash designs — with backlash down to […]
NORD extends single-stage, helical gear unit line with three new sizes
NORD Gear Corporation has added three single-stage gear units to its NORDBLOC.1 line. The new SK 871.1, SK 971.1 and SK 1071.1 represent the three largest single-stage NORDBLOC gear units manufactured by NORD and provide exceptional thrust load capacity per case size. The new products have a power range of 30 to 60 hp, a […]
NORD DRIVESYSTEMS gearmotors and drives support IIoT installations
Intelligent drive technology is key to digitalization and production automation, because it enables networked and autonomous production processes in smart factories. Here, NORD DRIVESYSTEMS supplies drive solutions (hardware and software) and communications and application support for Industry 4.0 environments. NORD DRIVESYSTEMS drive units support intelligent IIoT digitalized production with advanced maintenance services. The industrial motor […]
Why use a gearbox with a stepper motor?
Stepper motors are known for their accurate positioning capabilities and high torque delivery at low speeds, but they require careful sizing to ensure the motor matches the load and application parameters, to minimize the possibility of lost steps or motor stalling. Adding a gearbox to a stepper motor system can improve the motor’s performance by […]
Strain-wave gears and other components in off-highway + mobile robotics
Automated mobile equipment, which transports items in warehouses and freight centers as well as assembly operations, continues to boost demand for power-transmission and motion control systems. In fact, the worldwide mobile-robot market will reach nearly $15 billion by 2026, according to researchandmarkets.com. Almost all run off electric-motor drivetrains that are relatively expensive upfront but with […]
When to use gears to change the inertia ratio of a motor-driven system
In any system where a motor drives a load to achieve precise positioning, velocity, or torque, the ratio of the load inertia to the motor inertia plays a significant role in determining the motor’s ability to effectively and efficiently control the load, especially during acceleration and deceleration portions of the motion profile. In this context, the […]
Forest City Gear launches advanced facility for gear-blank production
Forest City Gear has expanded its turning and milling operations with a state-of-the-art facility designed to greatly improve lead times and quality for the production of precision gear blanks. This highly productive 8,500 sq. ft. facility is in close proximity to Forest City Gear’s main facility in Roscoe, IL, and now dedicated almost solely to […]
