Three Phase Electric Motors | Lafert
Lafert offer certain motor sizes in a reduced frame. For example – 2 pole 7.5kw 415v in a 112 frame (standard frame size is 132). We can also offer reduced frame flanges to suit. For example – 132/112 B5
AC motors are the driving force of most industrial machinery. This is the principal use for AC motors and it comprises the bulk of Lafert’s business. Today, the major factor influencing the motor industry is energy efficiency driven by both increasingly demanding legislation and industry’s greater awareness of green issue responsibilities.
Rated Voltage
The rated voltage of the three phase motors, EN 60034-1 allows a tolerance of +/- 5%. According to IEC 60038, the mains voltages may have a tolerance of +/- 10%. Therefore the three-phase motors are designed for the following rated voltage ranges (Exceptions are shown in the data tables)
Mains voltage to IEC 60038 | Rated voltage | Range of motor |
---|---|---|
230 V +/- 10% | 218-242 V +/- 5% | 50Hz |
400 V +/- 10% | 380-420 V +/- 5% | 50Hz |
690 V +/- 10% | 655-725 V +/- 5% | 50Hz |
