1. A hydraulic unit for providing a pressurized hydraulic fluid, comprising a motor arranged in a motor housing and a hydraulic pump arranged in a hydraulic housing, wherein the motor housing and the hydraulic housing are fluidically connected to one another,
wherein
at least one main flow connection, which is able to be subjected to high pressure, is guided between the hydraulic pump and an actuator through at least one first channel of the motor, and
at least one channel, which is able to be subjected to high pressure, for a main volume flow is guided through a stator of the motor.
