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.
