Abstract
An electric gear pump comprising a gerotor that may rotate about an axis of rotation A, comprising an external spur rotor and an internal spur rotor arranged outside the external spur rotor; a stator having electrical windings arranged outside the internal spur rotor; a surface covering coupled externally to the internal spur rotor; at least one magnet arranged between the internal spur rotor and the surface covering in such a way as to cause the gerotor to rotate when the electrical windings of the stator are supplied with current.
Claims11
An electric gear pump (4) comprising:
- a gerotor (9) configured to rotate about an axis of rotation (A), the gerotor comprising an external spur rotor (21) and an internal spur rotor (22) arranged outside the external spur rotor (21);
- a covering (29) connected externally to the internal spur rotor (22);
- a stator (25) having electrical windings (26) arranged outside the covering (29);
- and
- a magnetic structure (23) arranged between the internal spur rotor (22) and the covering (29) and rigidly secured to the internal spur rotor (22) in such a way that the magnetic structure (23) causes the gerotor (9) to rotate when the electrical windings (26) of the stator (25) are supplied with electric current.
