POSITIONAL RECOGNITION USING BEMF ZERO CROSSOVER RECOGNITION OF A ROTOR OF AN ELECTRONICALLY COMMUTATED ELECTRIC MACHINE WITH TWO COIL SECTIONS OF DIFFERENT INDUCTANCES
The invention relates to a method for positional recognition of a rotor of an electronically commutated electric machine, in particular an electric motor, in which a zero crossover of a voltage induced in a coil section of the rotor or stator is used for positional recognition. According to the inve...

Summary: | The invention relates to a method for positional recognition of a rotor of an electronically commutated electric machine, in particular an electric motor, in which a zero crossover of a voltage induced in a coil section of the rotor or stator is used for positional recognition. According to the invention, to determine the zero crossover the coil section is briefly powered down. A rotor/stator is used, comprising at least two coil sections, one of which has a lower inductance relative to the other one, and preferably only the coil section with the lower inductance is used for the positional recognition. |
