Motor datasheet reference

The codes on a servo or induction motor datasheet, each on one page: what the standard defines and what it means for picking a motor.

• IP ratings (IEC 60529): What the two digits of IP54, IP65 or IP67 mean for dust and water.
• Insulation classes (IEC 60085): Thermal classes A to H, and what "class F, class B rise" means.
• Duty types S1 to S10 (IEC 60034-1): What S1, S3 40 % or S6 means, and what it changes for sizing.
• Efficiency classes IE1 to IE5 (IEC 60034-30-1): The IE code on an induction motor, and the EU minimums.
• Metric prefixes (SI): Pico to tera: symbols, factors and where they show up on a drive.

For converting the values themselves, use the unit converter.
