Abstract: An electric coolant pump for providing an automotive cooling circuit with a coolant includes an electric motor to drive the electric coolant pump, a pump housing, a separating can, a printed circuit board, and permanently height-adjusted supporting elements. The separating can includes a substantially plane separating can bottom wall which lies in a cross plane, and a substantially cylindrical separating can shell which fluidically separates a wet zone from a dry zone. The printed circuit board is arranged substantially parallel to and not in direct contact with the separating can bottom wall so that an axial gap exists which is filled with a heat conductive means. The supporting elements axially support the plane printed circuit board. Each supporting element has a distal tip which is trimmed to define a height-constant axial gap having a nominal gap height between the printed circuit board and the separating can bottom wall.

Abstract: A motor vehicle pump arrangement includes a pumping unit having engagement steps, and a mounting arrangement which mounts the pumping unit to a motor vehicle mounting structure which corresponds to the pumping unit. The mounting arrangement includes a vibration-decoupling body having a ring shape, and a clip retainer which is attached to the vibration-decoupling body. The vibration-decoupling body radially surrounds the pumping unit, supports the pumping unit, and is attachable to the motor vehicle mounting structure. The clip retainer axially retains the pumping unit. The clip retainer includes a retainer frame which extends in a transversal pumping unit plane and which is axially supported by the vibration-decoupling body, and retainer arms which axially project from the retainer frame. Each of the retainer arms engages a respective one of the corresponding engagement steps of the pumping unit so as to axially retain the pumping unit.

The pumping unit has a substantially cylindrical pumping unit housing and at least one support protrusion which radially protrudes from the pumping unit housing. The mounting arrangement mounts the pumping unit to a motor vehicle mounting structure corresponding thereto. The mounting arrangement has a ring-shaped pump support body. The pump support body radially surrounds and supports the pumping unit and is attachable to the motor vehicle mounting structure. An axial side of the pump support body includes a castellated structure having axially extending merlons and protrusion receptacles. One protrusion receptacle is arranged between two adjacent merlons. The support protrusion engages with at least one of the protrusion receptacles.

Abstract: The invention rests on the idea that the information for controlling an EC-motor is taken from the adjustment or position of the control unit, which can be ascertained by means of a position indicator, such as a potentiometer, Hall indicator, etc. The current pattern for the EC-motor can thereafter, for example, be determined in a microcomputer disposed in the motor control for the control unit, without the motor having a rotor position determination.

Abstract: The electric motor comprises an internal rotor and an external stator with stator windings. The rotor comprises several permanently magnetic pole shoes. The stator windings are supported by stator pole shanks comprising, radially inside, stator pole shoes facing the rotor pole shoes. Via a short circuit bridge, the stator pole shoes are connected with the adjacent stator pole shoes so that all the stator pole shanks are integrally formed with each other. Radially outside, the stator pole shanks and stator pole shoes are connected with each other only by a separate yoke ring set thereon. All the windings are wound from radially outside with one single continuous winding wire when the yoke ring has been removed.
