Patent ID: 10103673

Abstract:
The invention is based on a motor apparatus, in particular on an EC motor apparatus, comprising at least one stator (12a; 12b; 12c) which has at least twelve coils (14a, 14a′, 16a, 16a′, 18a, 18a′, 20a, 20d, 22a, 22b′, 24a, 24a′; 14b, 14b′, 16b, 6b′, 18b, 18b′, 20b, 20b′, 22b, 22b′, 24b, 24b′; 14c, 16c, 18c, 20c, 22c, 24c, 142c, 44c, 146c, 148c, 150c, 152c), and comprising at least one power supply unit (26a; 26b; 26c). It is proposed that coils (14a, 14a′, 16a, 16a′, 18a, 18a′, 20a, 20a′, 22a, 22a′, 24a, 24a′; 14b, 4b′, 16b, 16b′, 18b, 18b′, 20b, 20b′, 22b, 22b′, 24b, 24b′; 14c, 16c, 18c, 20c, 22c, 24c, 42c, 144c, 146c, 148c, 150c, 152c), which directly follow one another in the circumferential direction (36a; 36b; 36c), of the at least one stator (12a; 12b; 12c) are connected to differing phases of the power supply unit (26a; 26b; 26c) in at least one operating state.
