Permanent-magnet synchronous electric motor with improved statoric group for circulation pumps of heating and conditioning systems

摘要

A permanent-magnet synchronous electric motor for circulation pumps of heating/conditioning systems of a uniquely simple construction and improved performance. The motor has a motor casing and a cross-like or star-like monolithic body inside the motor casing. The motor further contains a plurality of arms in the cross-like or star-like monolithic body forming the spools of a stator. The stator has a statoric core of laminations and statoric coils wound on respective spools.
