Drive & Motor Technology Drive & Motor Technology The widest range of motors and combinations adapted to the various needs of industries and applications The IMfinity® motor ranges (aluminium, cast iron, IP23 drip-proof and liquid cooled frames) are designed to allow a large combination of adaptations, such as gearboxes, brakes, speed feedback (encoders), forced ventilation units, etc. All of these motors, with or without special adaptation, are designed to work with variable speed drives, such as the Unidrive M & Powerdrive ranges. Global guarantee from a single manufacturer The...

IE2 IMfinity + Drive Compliant, costeffective, guaranteed performance ® The implementing regulation of the European directive allows for the possibility of combining a variable speed drive with an IE2 motor as an alternative to replacing it with a fixed-speed IE3 motor. In addition to ensuring installation compliance, choosing to convert to variable speed can also generate immediate operating profits thanks to: • Energy savings of up to 50% depending on the application and operating conditions • Reduced cost of maintenance on the mechanical control components • Better productivity as a...

Variable speed options As an answer to the majority of cases, the IMfinity offer has been designed integrating specific features as standard: • Standard PTC sensors • Thermal reserve for maintaining the rated torque over an extended speed range • Adaptation of the metal support plate to reduce electromagnetic noise However, to meet particular requirements, options available on short delivery can be provided: • Winding insulation and insulated bearing for mains voltages ≥ 480 V, long cable lengths and frequent operation during the braking phase • Forced ventilation unit for availability of...
