The BFK458-L has made a major improvement in the life of spring applied brakes. Guaranteed for 10,000,000 cycles or two years of service life the BFK458-L has a 250% longer life than most available brakes.
Lenze-AC Tech announces the addition of a low cost, long-life spring-applied break to their line of motion control solutions.
According to company officials, when properly applied, the newly released BFK458-L is guaranteed for 10,000,000 cycles or two years of service life. "The BFK458-L has a 250% longer life than most available brakes," states Lenze-AC Tech Regional Sales Director, Steve Greene, adding, "In high cycle applications, this represents a major product performance improvement."
Manufactured by Lenze-AC Tech partner, INTORQ the series BFK458-L are spring applied brakes that are released by applying DC voltage to an electromagnetic coil.
Regarding best applications for the new brakes, Greene mentions users interested in a low cost solution for stopping and holding duties in rapid, high cycling applications, and explains, "The BFK458-L will give our customers a tremendous advantage in high dynamic applications."
According to Greene, the BFK458-L brakes are constructed with a cast iron casing and come with a warranty which lasts 2 years or the guaranteed number of cycles, whichever comes first. Lenze-AC Tech engineers explain that there are four sizes in the range, with rated torques from 4 to 46Nm; shaft sizes start at 10mm and go up to 25mm and brake coils can be supplied for 24V low voltage connection or rectified mains at 103, 180 and 250V.
In Connection with MCS Synchronous servo motors and Lenze MCA asynchronous servo motors, this allows flexible and particularly energy-efficient solutions to be created that can handle virtually any application. The equipment includes all the options available as standard and all the built-on accessories of the product. The moments of inertia relate to the drive shaft of the gearbox. The total moment of inertia is calculated
Lenze is adding a new decentralised system to its 8400 frequency inverter platform. 8400 protec is the name of the new model, which offers a decentralised drive solution with an integrated safety system. The use of plug & play principles saves valuable time during installation and when servicing is necessary. With a power range from 0.75 to 4 kW, the compact drives are suitable for horizontal and vertical applications in the automotive,
