From 0.06 to 160 kW, Leroy-Somer brake induction motors are used for intermittent duty, emergency stops or for holding a device under load. They are designed to operate in normal or special environments.

Leroy-Somer offers a complete range of high-performance AC servo motors and geared servo motors. We also provide custom-built solutions for low voltage and direct drive applications.

Our servos are characterized by their high dynamic performance, precise motion control and high power density.

Our servo solution guarantees high reliability and short lead-times thanks to rigorous testing and the ability to offer late customization.

From 30 to 23 000 Nm, the range of geared motor technologies satisfies the demands of industrial processes for normal or special environments.

Simple, compact, high-performance Soft Starters & Electronic controllers with integrated motor protection.

Over a power range up to 1500kW, the range of IP65/IP55 enclosed or IP23 protected induction motors satisfies the demands of industrial processes for standard or special environments. IMfinity®: The new platform of high efficiency IE2, IE3, IE4 and non IE motors for variable or fixed speed. Motors from the new IMfinity® platform have been developed to guarantee efficiency levels for the main voltages and frequencies covering at least 80% of the power supplies throughout the world, while complying with existing or future energy regulations.
