AC inverters that are electrically connected to a direct current source to convert the direct current source such that the transistor power module of an inverter can power a plurality of AC motors wherein the motors can be located remote from the inverters or within the inverter housings.

An electro-hydraulic power unit is disclosed that includes a housing filled with hydraulic fluid. A hydraulic power unit is disposed within the housing, the power unit having a mechanical power shaft. Additionally, an electric machine is disposed within the housing adjacent to the hydraulic power unit, the electric machine having a rotor secured to the mechanical power shaft of the hydraulic power unit. Hydraulic fluid within the housing passes over the electric machine, thus cooling the electric machine and providing for improved efficiency and performance.

An electrical steering system for a vehicle includes an electrically supplied steering motor arrangement which is connected with an inverter arrangement, whose output voltage is influenced by a computer arrangement, and a sensor arrangement. To reduce the cost of the steering system while also allowing the steering system to be steerable during braking in the case of a fault, the steering motor arrangement has a redundant steering motor which is connected with the computer arrangement via two separately run control circuits. The control circuits have separate electric supplies and the computer arrangement is redundant.

Electrical steering system

A steering device with a steering angle transducer, a steering drive having a motor and a first gear, at least one wheel driven by the steering drive and a sensor arrangement for detecting the angle position of the wheel with a detection device, which produces a reference signal for at least one reference position of the steering device. In this connection, it is desired to improve the reliability of the steering device. For this purpose, the detection device is connected with the motor via a second gear.
