IMfinity® 3-phase induction motors - IE2 - IE3 - IE4 - Non IE Efficiency General General information Directive and standards relating to motor efficiency There have been a number of changes to the standards and new standards created in recent years. They mainly concern motor efficiency and their scope includes measurement methods and motor classification. Regulations are gradually being implemented, both nationally and internationally, in many countries in order to promote the use of high-efficiency motors (Europe, USA, Canada, Brazil, Australia, New Zealand, Korea, China, Israel, etc). The...

IMfinity® 3-phase induction motors - IE2 - IE3 - IE4 - Non IE Efficiency General General information Standards and approvals MAIN PRODUCT MARKINGS WORLDWIDE There are lots of special markings throughout the world. They mainly concern product conformance with current user safety standards in different countries. Some markings or labels only concern energy regulations. The same country can therefore have two markings: one for safety and one for energy. USA: energy efficiency conformance logo (optional). USA and Canada: EISA conformance logo (optional). This marking is mandatory for the...

IMfinity® 3-phase induction motors - IE2 - IE3 - IE4 - Non IE Efficiency General Environment Heaters SPACE HEATERS Severe climatic conditions, e.g. T amb < - 40°C, RH > 95% etc, may require the use of space heaters (fitted to one or two winding end coils) which serve to maintain the average temperature of the motor, provide trouble-free starting, and/or eliminate problems caused by condensation (loss of insulation). The heater supply wires are brought out to a terminal block in the motor terminal box. The heaters must be switched off while the motor is running. D.C. SUPPLY INJECTION...
