L-force Three-Phase MF Motor. The cost-effective and innovative MF Motor increases efficiency during partial load and reduces energy use by up to 30% when operating with a frequency inverter. This is a Control Engineering 2012 Engineers’ Choice finalist.Lenze Americas’ compact, dynamic, and efficient three-phase motor increases efficiency during partial load and reduces energy use by up to 30% when operating with an 8400 series inverter. The cost-effective and innovative MF Motor can be up to two sizes smaller than conventional asynchronous motors with the same rated power. 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%, 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. To fully leverage the advantages, Lenze recommends combining the MF motor with an 8400 series inverter, which comes equipped with its energy-saving VFCeco (Voltage Frequency Control Economic) function. VFCeco automatically adapts the magnetizing current of the MF Motor to the operating conditions, increasing efficiency during partial load and reducing energy use by up to 30%. The L-force MF three-phase ac motors are an industry first motor series combining compactness, dynamic performance, and energy efficiency and tailored for L-Force 8400 frequency inverter operation.

Annual Salary Survey

Participate in the 2013 Salary Survey

In a year when manufacturing continued to lead the economic rebound, it makes sense that plant manager bonuses rebounded. Plant Engineering’s annual Salary Survey shows both wages and bonuses rose in 2012 after a retreat the year before.

Average salary across all job titles for plant floor management rose 3.5% to $95,446, and bonus compensation jumped to $15,162, a 4.2% increase from the 2010 level and double the 2011 total, which showed a sharp drop in bonus.
