FIELD: electric engineering, namely - electric machines. ^ SUBSTANCE: invention claims new design of collector multi-pole constant current electric motor, which uses constant magnets in stator, which require no electric power, having minimal number of brushes as opposed to multi-brush analog, namely two brushes for any even number of stator poles. In accordance to the invention, in electric motor, containing stator, and also rotor with open or closed winding, having contacts connected to collector and brushes, the stator is made multi-pole and uses constant magnets, and collector represents two contact systems on non current-conductive base, mutually isolated and enclosed in each other in such a way, that during rotation of rotor from contact to collector contact direction of current in rotor winding changes to reverse by means of two brushes, which may touch any pair of collector contacts of various aforementioned systems, where the start of rotor winding is connected to one system of collector contacts, end of rotor winding is connected to another system of collector contacts, and a "false" contact is present between each pair of contacts of aforementioned systems, which is not connected to rotor winding to prevent shorting of two contacts of different polarity by one brush, while stator does not require power. A working experimental model exists, which fits well with balance wheel rotation theory. Rotor diameter 20 cm. Rotor weight 3,5 kg, and it is mainly positioned around its outside circle. Rotor rotation speed 3 revolutions per second. Power consumption of 50 Wt. Voltage, fed into winding, of 12 volts. Current intensity of 4 amperes. ^ EFFECT: due to aforementioned new features and special design of collector the electric motor has better efficiency compared to analogs. ^ 2 dwg |
