IMfinity®Liquid cooled motors - LC series

2023-09-11

■In this catalog, Leroy-Somer describes high-efficiency liquid-cooled induction motors. These motors have been designed to
incorporate the latest European standards, and can satisfy most of industry's demands. They are par excellence the leading
products on the Leroy-Somer liquid-cooled IMfinity® platform.

■Liquid-cooled motors are particularly suitable for and are used in applications requiring a low noise level, high output power with
IP55 protection, compact dimensions and operation on a drive.

■Advantages 

●Motor cooled by a water circuit integrated in the housing (IC71W) 

●Reduced noise level: the water cooling system means the fan is no longer necessary and ensures a reduced noise level
(between 60 and 80 dB (A) in LpA 

● IE3 Premium efficiency across the whole range: 150 to 1500 kW - 2, 4 & 6-pole 

● Compact design: weight and dimensions can be as much as 25% less than an air-cooled IP55 motor, and as much as 55% less
than an IP55 motor cooled by an air/water exchanger (IC81W) 

● Degree of protection higher than IP55 (e.g.: IP56) as an option 

● Motor adapted for use at constant torque across the entire speed range from 0 to 50 Hz, without derating. The motor is always
cooled, whatever the point of operation. 

● Reduced vibration level 

● Heat recovery thanks to dissipation of losses by an external water circuit
