摘要:
A brushless direct current motor including a rotor having permanent magnets, which rotates in a commutation created alternating magnetic field of a stator (1) is provided, which magnetic field is created by a coil system of wire coils (3) applied on an insulating body (4) in the circumferential direction and spaced apart from each other. Control electronics are provided for controlling the electric wire coils, spaced apart from each other, of the control system provided in the stator (1), with non-contact rotary position sensors (5) being allocated to the phases of the coil system (2). In the direct current motor according to the invention the rotary position sensors (5) are arranged on a sensor carrier (13). The sensor carrier (13) can be fastened at least at one face of the stator (1), and positioning aids cooperating with each other are arranged between the sensor carrier (13) and the adjacent stator face, which determine a relative position of the stator (1) in reference to the sensor carrier (13) and the rotary position sensors (5) arranged thereupon. If applicable, the direct current motor can be produced in an automated production method with little expense.
