Modular sets of extraneous (forced) ventilation are designed for use in electric motors with adjustable speed (e.g., when powered by an inverter) - in drives with constant-torque load characteristics as a function of speed [T=f(n)=const.], such as presses, conveyors, centrifuges, gearboxes, etc.

The use of an independently powered fan with constant performance, ensures that the motor shaft torque is constant within the control range of 0÷100% of the rated speed.

Ready-made external ventilation kits are adapted for mounting on engines after removing the standard cover and vent.

The basic offer includes sets for motors of mechanical size 63÷180, with a fan powered by 1-phase 230VAC.

Fan modules for IEC size 200÷450 motors - available on request.
