The new Unimotor fm servo motor controlled by a LEROY-SOMER DIGITAX ST servo drive or a LEROY-SOMER UNIDRIVE SP universal drive, provides the user a guarantee of performance. This is the optimum solution for applications requiring a high dynamic response. Combined with the LEROY-SOMER Dynabloc servo gear unit range, the Unimotor fm servo motor covers a large torque range at the same time as meeting the need for a highly compact drive system. LEROY-SOMER offers therefore an incomparable range taking account of the constraints encountered by industrial automation applications.

The new Unimotor fm servo motors, with an IP 65 standard protection, covers torque requirements from 0.75 to 410 N.m with a high peak torque capability. The rotor and the stator have been specially designed to provide a high rigidity of the shaft, a very high axial or radial load capacity, a choice of several different shaft diameters. The windings enable the motor to operate at voltages such as 200-240 V and 400-480 V and at high carrier frequencies.

Its modular design meets the users’ requirements due to numerous possibilities of mechanical and electrical adaptation: up to three shaft and flange diameters, finish with keyed or solid shaft, up to eight nominal speeds, choice of speed feedbacks, two parking brake ranges…

The Unimotor fm servo motors, combined with the LEROY-SOMER servo drive systems, demonstrate all the advantages to meet the most demanding and dynamic applications in a reduced footprint, typically transfer machines, initial wrapping, printers, laser or waterjet cutting, special machines...
