G-300Gearless
G-300 is a gearless model with permanent magnet synchronous motor and die-cast aluminium casing.
Benefits:
- anodized on the surface to guarantee resistance to external factors;
- with vertical finning for improved heat dissipation;
- equipped with height-limiting, lowered terminal box.
Extreme quiet operation, essential in roomless systems.
Easier adjustment than all major inverters for elevator use available on the market.
Equipped with the proven DF modular braking system, developed and built independently by Alberto Sassi S.p.A in the Crespellano (BO) plant.
Mounting high-efficiency and silent axial fans on the gearless G-300, achieving +20% drive torque* compared to the fanless version.
G-300 T2 version: The greater increase in drive torque had to be compensated by an adequate safety margin on the emergency brake to meet the stringent A3 amendment limits.
The T2 series, therefore, mounts a DF02 brake with a certified minimum braking torque of 1300 Nm but retains the same fixing spacings as the T1 series.
Available in 2 types
- TC with centered pulley, positioned between motor block and service brake.
- T0-TS-T1-T2 with cantilever pulley, TS and T2 versions with enhanced motor torque for high performance. In version without fan and brake levers, IP66 water and dust resistant can be added.
