ABSTRACT:
The invention relates to electric motors, particularly to low-voltage gearless commutator motors, and can be used as motor-wheels in transportation vehicles and in other technologies. The aim of the present invention is to provide an electric motor with increased performance characteristics, relatively simple design, and high reliability. A pulsed inertial electric motor according to the invention comprises: (i) a stator with circular magnetic conductor on which an even number of permanent magnets are uniformly arranged with a certain pitch; (ii) a rotor separated from the stator by air gap and bearing an even number of electromagnets, each electromagnet consisting of two coils with opposite winding directions connected in series, which are arranged over the circle in pairs one opposite to another; (iii) a collector distributor mounted on the stator body, containing circularly arranged current-conducting plates separated by insulating spacers and connected with alternating polarity to a dc current source, and (iv) current collectors-brushes mounted on the rotor and capable of contacting with plates of the collector distributor, whereby all brushes are connected to identical (beginning or end) terminals of the windings of said electromagnets and interconnected so that the coils in the opposite electromagnets are connected to each other via one identical terminal and to the opposite brushes via another identical terminal, with the number n of permanent magnets in the stator and the number m of electromagnets in the rotor selected so as to obey the relationsin-line-formulae description="In-line Formulae" end="lead"?n=10+4k,in-line-formulae description="In-line Formulae" end="tail"?in-line-formulae description="In-line Formulae" end="lead"?m=4+2l,in-line-formulae description="In-line Formulae" end="tail"?where k is an arbitrary integer (k=0, 1, 2, . . . ) and l is any integer such that 0≦l≦k.
