Product Detail:
LAFERT T24 – T32 Gearless Lift Machine Motors
Fractional slot concentrated winding synchronous permanent magnet machines.
Setting the standard for the lift market: high-torque density, high efficiency and fault-tolerance performance.
The motor’s innovative design, with its protected encoder and no external cabling, offers compactness and low weight, ideal for home lift systems or new concept M.R.L..
Its novel inner rotor and fractional slot gearless technology are of products of Lafert’s in-house design and manufacturing expertise. It provides the highest levels of performance and energy efficiency plus enhanced response to satisfy today’s needs and trends in the elevator market i.e. higher speed to greater heights.
