) Note!
l 4−pole asynchronous motors which are designed for a rated frequency of 50Hz
in star connection, can be operated in delta connection if the constant
excitement does not exceed 87Hz.
– The motor current and the motor power increase by the factor 3=1.73.
– The field−weakening range starts above 87Hz.
l Advantages:
– Higher speed−setting range
– 73% higher power output with standard motors.
l In principle, this method can also be used for motors with other pole numbers.
– Observe the mechanical limit speed when using 2−pole asynchronous motors.
