<p>An electronically switched electric motor structure (100) comprising: a casing consisting of a front half shell (12) and a rear half shell (11) able to contain the various members of the motor, a stator unit (20) provided with stator windings (60) and mounted integral with the casing, a rotor (30) disposed inside the stator unit (20) and integral with a drive shaft (31), and control electronics (80) mounted on a circuit board (70) supported by a rear insulating support (50) mounted in the rear part of the stator unit (20). The rear insulating support (50) comprises a closed rear flange (52) made of insulating material, which has, in its front surface, a seat to receive a bearing or bushing (58) able to support rotatably a rear end (33) of the drive shaft (31), so that the electronics (80) of the motor is insulated from the electrostatic charges generated by rotation of the drive shaft (31). <IMAGE></p> |
