MOTOX D88-LA100L4 Coaxial Helical Gearmotor
The iconic MOTOX gearmotor series was originally created and engineered by FLENDER. Following Siemens' acquisition of Flender, MOTOX was integrated into Siemens' drive portfolio under the 2KJ catalog line (2KJ1205 for D88). Subsequently, Siemens carved out its heavy-duty motors and gearmotors business under the INNOMOTICS brand. Today, MOTOX products have transitioned back to the original manufacturing plants and authentic OEM supplier channels, ensuring 100% exact design continuity, mechanical interchangeability, and original quality standards.
The MOTOX D88-LA100L4 is a 3-stage coaxial inline helical gearmotor offering high mechanical efficiency (94%), rigid cast iron housing construction, and compact inline layout. Cataloged under Siemens 2KJ order code 2KJ1205, the D88 size delivers nominal output torques up to 1,600 Nm and is paired with 1.5 kW LA100L4 motors. Designed for heavy industrial power transmission, conveyor drives, agitators, and roller tables, MOTOX coaxial helical gearmotors are available in versatile configurations (foot D88, B5 flange DF88, B14 flange DZ88, and agitator flange DR88) ensuring high overhung load capacities and extended service life.
