Lenze Americas (Uxbridge, MA) has
released the L-Force Three-Phase MF Motor
design for operation with a frequency inverter.
The motor can be up to two sizes smaller
than conventional asynchronous motors with
the same rated power. Available in power
ranges from 0.55 to 22 kW, the motors feature
the modular system of the L-force threephase
AC motors. With efficiency levels of 94 to 98 percent, the rightangle
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.
This week’s Question: The Department of Energy (DOE) has set a goal of building a battery that stores energy for less than $100 per kilowatt-hour, making stored wind and solar energy competitive with energy produced from traditional power plants....
