Definitions
- the present invention relates to a coolant pump for vehicles according to the preamble of claim 1.
- Electric coolant pumps have the advantage over mechanically driven coolant pumps that the effective pumping capacity can be regulated in a simple manner in accordance with the current cooling requirement. This is especially relevant in the starting phase, since the engine reaches its operating temperature faster with an optimally controlled coolant pump, which has a positive effect on fuel consumption and exhaust emissions. Electric coolant pumps are also relevant to electric vehicles whose batteries need to be cooled, at least in some operating conditions.
- coolant pumps are currently being used, which are driven by brushless electric motors with external coils, in which the inner rotor equipped with permanent magnets and the associated impeller run in the coolant. Pumps with internal rotor motors are z. B. also known from process engineering or heating and correspondingly large and heavy. Due to their size and weight, therefore, the known from the automotive field electric coolant pumps have not been able to prevail in the motorcycle field.
- the object of the invention is to provide an electrically driven coolant pump, which has a compact design and low weight and which is particularly suitable for use in the motorcycle area.
- the basic principle of the invention consists in a coolant pump which is driven by an "external rotor motor.”
- the rotatably arranged rotor or rotor is arranged radially outside the stator provided with one or more electric coils.
- “Radially outward” means that the rotor in FIG Circumferentially distributed a plurality of permanent magnets are arranged, which are arranged radially outside of the stator coil.
- FIG. 1 shows a cross section through an electric coolant pump according to the invention.
- FIG. 2 shows the rotor of the coolant pump shown in Figure 1 in a perspective view.
- FIG. 1 shows an electric coolant pump 1 which has a housing 2 and a brushless external rotor motor 3 arranged therein.
- the Brushless external rotor motor 3 which is also referred to below as an electric motor, has a stator 2 screwed to the housing 2 with a plurality of stator coils 5, which are supplied via a led out of the housing 2 electrical connection line 6 with power, and a rotor or Runner 7.
- the stator 4 has a cylindrical recess 9 extending in an axial direction 8 of the coolant pump 1.
- two bearings 10, 11 are arranged, in which, for. B. may be ceramic bearings or plain bearings.
- the bearing distance can be increased compared to the construction of a conventional water pump.
- the front bearing sits closer to the force application point. Therefore, the bearings can be made smaller, which is the size of the good.
- the rotor 7 has an impeller 7a, a rotor shaft 7b and a circular cylindrical portion 7c protruding in the axial direction 8 from the rear side of the impeller 7a, on the inside of which a plurality of permanent magnets 12 are distributed in the circumferential direction. There is a narrow annular gap 13 between the circular-cylindrical section 7c or the permanent magnet 12 and the stator coils 5.
- the rotor 7 is rotatably mounted in the stator 4 via the rotor shaft 7b and the two bearings 10, 11.
- the housing 2 may be completely filled with coolant. Through a partial flow return to the suction side, e.g. Via bores 7d in the impeller 7a, a cooling of the stator coils can be achieved.
- the stator coils 5 are coated with a protective layer 14.
- the protective layer 14 may be, for. B. a lacquer layer or a rubber layer.
