Golden Mousetrap Awards: The Winners!

Lenze Americas
Three-Phase MF Motor
The compact, cost-effective, and innovative L-Force Three-Phase MF Motor by Lenze Americas can be up to two sizes smaller than conventional asynchronous motors with the same rated power. Combining the L-Force MF Motor with an 8400 series inverter increases efficiency during partial load and reduces energy use by up to 30 percent.

The MF Motor features a wide speed setting range of 1:24, about twice as fast as conventional motors. Due to the higher rotational speed of the MF motors, a size 71 device, for example, is sufficient for a rated power of 1.5 kW that would otherwise require a size 90 conventional three-phase motor.

Available in power ranges from 0.55 kW to 22 kW, MF three-phase AC motors bridge the gap between conventional AC motors and the high dynamic performance of servo motors. The well-known modular system of the L-force three-phase AC motors provides optimal design flexibility. With efficiency levels of 94 to 98 percent, the right-angle and in-line gearboxes ensure that energy output by the motor is transferred to the application with minimal losses. A correspondingly higher gearbox ratio compensates for the improved motor speed.

MF Motors are compatible with either a central control cabinet drive or a decentralized motor inverter. The smaller frame size of the combined Lenze L-force drive package makes the entire design more cost-effective. Compactness, dynamic performance, and energy efficiency are features thus far only associated with more expensive motors. The introduction of L-force MF three-phase AC motors is an industry first -- a motor series combining all three and tailored for L-Force 8400 frequency inverter operation.

Congrats to the winners in every category, and thanks to Rich, Al Schmidt, Jenn, Lauren, and everyone else who made it all go smoothly. Punya Prakash completely deserved the RES award. I admit I voted for her, but to meet her in person and see her gracious and inspiring acceptance speech was an amazing experience. I think we've started something big and I'm glad to have been there.

Awesome Venue for Technology Accomplishments

What a great way to bring these technological accomplishments to the forefront - I really appreciate a venue that allows hardworking designers creating innovative products to showcase their efforts and there is some fantastic work here. I was thinking it would be really neat to do this at another level with high school kids. We already have science fairs and robotic competitions but wouldn't it be cool for sponsoring companies to help budding engineers actually bring their inventions to the marketplace?
