Abstract (en)
Pump unit 26 for pressurising a hydraulic actuating system 21 including a pump housing 261 with a pump chamber 264 for housing a pump and an electric motor 3 for driving the pump. The electric motor, a brushless DC motor, comprises a motor rotor 31 with several magnets 33 at an outer surface, and a field coil positioned opposite the magnets for rotationally driving the motor rotor. The pump unit further comprises a control unit 29 including a printed circuit board PCB for controlling the electric motor. The control unit and a closure 29, 265 form a subassembly which is mountable as a module to close the pump chamber. The control unit comprises at least one Hall sensor 34 to detect a rotational position of the motor rotor. The at least one Hall sensor is positioned on the printed circuit board being positioned opposite a motor rotor end face 612.
