ABSTRACT:
BACKGROUND OF THE INVENTION
Technical field and Prior Art
The present invention relates to a rotary electric motor which has a single, predetermined direction of rotation and which can be controlled in respect of its supply with current and its speed by a simple electronic circuit. The motor is a further development of the type of motor described and shown in Swedish Patent Application 8802972-3 (=WO 90/02437).
OBJECT OF THE INVENTION
The motor described and illustrated in the aforesaid Swedish patent application has been found to function very well and affords all of the advantages recited in the application. Continued development has shown, however, that further improvements in the form of lower manufacturing costs and/or higher motor torque can be achieved without change of the motor size, at least for some fields of use, by constructing the motor in a manner which deviates slightly from the manner described in the aforesaid Swedish patent application.
According to the present invention, these further improvements are obtained with a motor constructed according to the invention, without losing any of the advantages afforded by the basic motor design, as described in the aforesaid patent application.
