摘要: A control device for brushless motor comprises an inverter (3), a circuit (8) and rotor position detecting (9). In the (9), voltage induced in stator coils (U, V W) due to rotation of (7) neutral at virtual point (25) are compared by comparators (CU, CV CW) so that polarity changing points can be detected. The controls (3) based on above stated as changeover modes conducting W). As result, controlled without using Hall elements.
