发明名称 Brushless electric motor, particularly for direct driving of a washing machine
摘要 The motor comprises a rotor (30) fixed for rotation with a shaft (36) of a member to be driven and a crown-like stator (10) obtained by blanking a lamination stack (12) provided with coil supporting teeth (11). Within the stator crown (10) there are obtained by blanking the lamination stack (12) a plurality of receptacles (13, 15, 17) for seating electric and electronic components associated with the stator. The components comprise a transformer (24), an inductance coil (25), and a plurality of MOSs (23). The stator crown (10) is co-molded with a covering of electrically insulating plastic material to cover the receptacles (13, 15, 17) and the teeth (11) and form a tank (22) for receiving a printed circuit (21). The permanent magnet rotor is fitted with stacks of small pieces (19) obtained by blanking lamination portions within the stator crown (10). The stacks of small pieces face the magnets (31) so as to close the respective magnetic circuits.
