LS63/T - Leroy-Somer 0.12 kW gearmotor with chain sprocket

Leroy-Somer LS63/T Gearmotor 0.12 kW with Chain Sprocket

The Leroy-Somer LS63/T gearmotor is a drive unit originally fitted on a Sorim Texpro transfer calender. It delivers low-speed, high-torque rotation through a single-chain sprocket on its output shaft.

It combines a Leroy-Somer three-phase asynchronous motor (0.12 kW, 1380 rpm at 50 Hz) with an integrated worm reducer, for high torque at low output speed and quiet, steady running. Supplied as a complete unit (motor + reducer + sprocket), ready to refit.
