Lafert, in its own words, specialises in supplying both single and three-phase motor solutions of non-standard design.
Until 2001, the company’s brake motors were marketed as part and parcel of the Lafert product mix, but it now handles this range as a more discrete product line, creating a division with specific responsibility to develop the product and expand its markets whilst offering specialised technical support.
The firm currently claims to have 5% of the European brake motor market but expects to raise that to 10% by 2010, “principally through further sales growth in the lifting market,” it said. It also operates globally, supplying custom-engineered single- and three-phase motor solutions (90% of production is non-standard).
Two of the company’s brake motor ranges have been developed specifically with heavy duty lifting tasks in mind: the AMF (high torque AC brake) and AMBY (high torque DC brake).
The AMF three-phase brake motor offers a high-torque AC brake (1.5-250Nm) with double braking surface as standard. “It is ideal for every heavy duty application and wherever a high frequency braking combined with power and precise operation is needed,” Lafert said. Such applications include cranes and industrial hoists.
The AMF is available in varied frame sizes with power outputs from 0.12-22kW with the same wide speed range as Lafert’s standard motor. It can also be supplied with a DC brake as an option.
Series AMBY has a DC high-torque brake (1.8-250Nm) with double braking surface as standard. Major features of this motor are “its progressive noiseless braking and its wide range of add-on options, such as encoders, axial independent cooling fan hand release lever and special brake designs,” Lafert added.
