Core Subjects

October 1, 2019
magazine. Instead of focusing on a specific industry, we focus on specific subject: namely, the mechanical power transmission components that drive many different types of machinery. So we find ourselves continuously writing about the same things: gears, bearings, motors, gear drives and so on. But this is a good thing.

Saving Money with High-Efficiency Gearmotors

October 1, 2019
Standing in a factory or a warehouse, you're bound to notice machinery, whether it's a conveyor system that winds across the floor or large fans that hang from the ceiling. You may even notice automated guided vehicles or autonomous mobile robots carrying parts, driving themselves from one section of the building to another. These machines are good candidates for using high-efficiency gearmotors, especially if they're expected to run for long stretches at a time. If they aren't using high-efficiency gearmotors, then they may be costing more money than they should.

General Modeling Method of Power Losses in Transmission with Parameter Identification

October 1, 2019
In this paper, the models for different power loss sources in transmissions from literature are applied and compared, which form the two methods - ISO 14179-2 and the joint model to estimate the power losses in a transmission. A 2-speed transmission in an electric vehicle is used as a case study to compare the two methods and validate them with experimental data.

Validation Approach of PM Gears for e-Drive Applications

October 1, 2019
Key technical drivers which can be addressed by advanced PM manufacturing technologies are, for example, the need for system downsizing in transmissions and differentials, the need for developing systems with higher power density and the strong NVH (Noise Vibration Harshness) requirements - especially for electrified transmissions or e-axle solutions.
