PLSES 4500 IMfinity® Platform IP23 high-speed induction motors Industrial refrigeration Variable speed Frame size 225 to 315 100 to 480 kW

PLSES 4500 The answer to the highly demanding cold storage sector Companies that use industrial refrigeration equipment have long been aware of the impact that the power consumption of a refrigeration installation can have both on energy bills and on the environment. The cold compressor, at the heart of the system, remains the most energy-consuming element, and can represent up to 80% of total consumption. OEMs or integrators seek to reduce drastically the power consumption of their machines while maintaining maximum levels of reliability. The use of high-efficiency motors combined with speed...

Dedicated to high speed • Tested and qualified Designed to operate at variable speed, the PLSES 4500 has been tested and qualified with Leroy-Somer Powerdrive MD2 high-power variable speed drives, guaranteeing optimum electrical and mechanical performance, obtained thanks to the use of components selected to work together. • Rated torque across the entire continuous duty speed range PLSES 4500 motors deliver their rated torque over a range from 1000 to 4500 rpm, offering notable power gains at the refrigeration compressor output. • Quality of the rotating components The choice of robust rotating...

PLSES 4500 Major assets Robust mechanics • Robust design based on simulations and tests • Machining of complete stator on mandrel for perfect concentricity from magnetic motor axis • Rigorous balancing for reduced vibration levels (class A across the entire speed range) Bearings suited to variable speed • Insulated non-drive end bearing (NDE) to avoid shaft currents (insulated DE bearing optional) • Longer service life and lubrication intervals Rotating components protection • Grounding ring as standard for redirecting shaft currents • High protection of the motor and driven machine bearings

Easy wiring • Large terminal box for easier access and safer connections • Connecting bar and grounding braids in terminal box for eliminating HF interference Improved cooling Complete optimisation of the motor cooling system to: • reduce losses • prevent hot spots and excessively high temperatures in the bearings • minimise noise levels Optimised characteristics • Electric core designed and characterised to work with a speed drive • Magnetic circuit optimised to reach IE3 efficiency class Thermal and mechanical protection • PTC sensors included in winding as standard. Other sensor models available...
