Gearless G-300

16 poles​

With the aim to update and improve the range of performances of gearless machines without decreasing the duty cycling factor (ED) now there is the possibility to add forced ventilation featuring highly efficient and noiseless axial fans to G-300.

With cooling fans G-300 T0 have increased torque by 20% compared to the version without cooling fans, while in type G-300 T1 we preferred to develop a new model the G-300 T2 since the increase in torque had to be compensated by updated braking safety conditions in order to fulfill the requirements of Amendment A3.

Type G-300 T2 has a brake DF02 with minimum braking torque certified at 1300Nm with the same fixing distance between centers as G-300 T1 but with an increase in length by 32mm.

Some examples: the duty load limits of G-300 T2 roping 1/1 is now 630kg (previously 450kg) while in roping 2/1 is 1250kg in comparison to 1000kg of type T1.

Please refer to the new duty tables indicating the duty load conditions requiring the ventilation groups or contact our sales office for more information.​

​Innovative casing of die-cast aluminum:​​​​
  • With anodized surface in order to guarantee its resistance against external agents
  • Vertically finned for an improved thermic dissipation
  • Equipped with lowered terminal board box to reduce its dimension in height

Extreme working noiselessness (essential for room-less installations)and easier regulation of main inverters for lifts which are currently available on the market.​

Equipped with modular breaking system DF, developed and manufactured by Alberto Sassi S.p.A.
