Abstract

PURPOSE:To enable exchanging electric circuits easily by providing a housing and a bracket supporting a rotor separately and by removably installing an electric circuit for driving a motor between the housing and bracket. CONSTITUTION:Electronic circuit elements such as transistor and capacitor are arranged in the substrate of a driving circuit 20. The driving circuit 20 is built in a space 28 formed between housing 14 and a bracket 18 and fixed to the housing 14. Also, a Hall element 22 for detecting the rotational position of a rotor 16 is arranged in the driving circuit 20 so that the Hall element 22 can be removed simultaneously with removal of the driving circuit 20. When the driving circuit 20 is faulty, it is sufficient to remove not only the bracket 18 but also the driving circuit 20 from the housing 14 and to fit the repaired driving circuit 20 again to the housing 14.
