A collectorless DC motor with a horizontal air gap, particularly a low-speed motor for a direct drive of recording and/or reproducing devices has its rotor axle supported within an axial bore of the motor housing, with the motor housing made of plastic. A tachogenerator is disposed about the inner cylinder formed by the rotating permanent magnet ring of the motor. The stator winding and the magnetic return structure are fixedly arranged on the motor housing, which is also provided with bores for attaching the motor or installing it into the device. Obviating of machining sequences, simplification of assembly and direct support of the rotor axle in the motor housing all contribute to a reduction in manufacturing cost.
