Excercises 3-Phase Induction motor Part 1: Checkbox tasks - only one is right at a time! 1. On the rating plate of a three-phase asynchronous motor is indicated 230/400 V star / delta. This motor should be connected to a supply voltage of 400V. Which statement is correct? The winding is not suitable for operation with a frequency converter. The winding is not suitable for star-delta starting with a mains voltage of 400 V. The winding must be switched to star at 690 V mains voltage. The motor winding is suitable with a mains voltage of 400 V for star-delta starting. The winding is only suitable for star-delta starting with a mains voltage of 400 V. 2. The picture shows the name plate of a three-phase induction motor. Which information is indicated inter alia on this name plate? Name plate for 3-Phase-Induction motor The voltage, the current and the electric power The work, the voltage and the number of revolutions The current, the work and the number of revolutions The voltage, the efficiency, and the rotaional speed The voltage, the current, the number of revolutions and the mechanical output power Loading … Part 2: ....coming soon < Previous Page | Next Page >
