Abstract
A method for producing a brushless DC (BLDC) motor includes: providing a stator, a rotor having a shaft and a carrier element having a cutout through which the shaft passes, on which surface a plurality of Hall sensors are arranged with respect to the center point of the shaft, the carrier element being arranged fixedly with respect to the stator; prefixing a permanent magnet wheel with transducer magnets, on the shaft on a side of the carrier element facing away from the rotor magnet; setting the shaft into rotary motion, and detecting measurement signal profiles of the Hall sensors and measurement signal profiles representative of voltages induced in the coils depending on the rotor magnets; determining an adjustment angle for the permanent magnet wheel; rotating the permanent magnet wheel with respect to the shaft corresponding to the determined adjustment angle; and fixing the permanent magnet wheel on the shaft.
