3-phase-induction motor plate - the most important informations (according to IEC 60034)
Motor plate 3 phase induction motor
- Shaft power P in kW with a nominal load
- Power factor cos φ
- IP- International Protection , also called Ingress Protection, classifies and rates the degree of protection of casings and enclosures. and water by The IP code is indicated by 2 numbers: First number: Degree of protection provided against intrusion, second number: Protection against water.
- Nominal rotational speed
- Rated voltage and electrical connection. Here, the motor may be connected to delta at 400 V mains voltage.
- Phase current at nominal speed
- Rated frequency
- Insulation class - specifies the thermal resistance of the motor winding.
Work order: Calculate the necessary electrical power, the torque and the efficiency at nominal range from the specifications of the motor plate shown above!
