FIELD: electrical engineering.
SUBSTANCE: brushless motor comprises a housing with a stator with magnetic poles, a rotor and a rotor position sensor. Rotor is connected to external electronic switch by optocoupler and is made in the form of impeller. Optocoupler is formed by blades of rotor (impeller), which are converters of optical radiation, and two sources of powerful optical radiation directed to blades of rotor (impeller) using system of optical radiation delivery. High-power optical radiation sources are located on geometric neutral of stator magnetic poles. They are also connected in series to external electronic switch with possibility of providing coordinated position with stator magnetic poles and blades of rotor (impeller).
EFFECT: technical result consists in expansion of operating ranges of power and simplification of design.
