摘要： The invention relates to a method for starting at least one asynchronous electric motor of a large hydraulic excavator having a service weight > 100 t and having an electrohydraulic drive, in that the particular electric motor is transferred from an idle position to an operating position by using a three-stage motor starting process, wherein the volumetric flow rate of at least one hydraulic pump operatively connected to the electric motor is set to the delivery rate V = 0 during all starting stages of the electric motor and the delivery rate V of the hydraulic pump is controlled to a value > 0 only after the last starting stage of the electric motor by activating an actuator.

摘要： An induction motor of the outer rotor-type in which rotor windings are arranged on the outer side of the stator winding. When applied to industrial machinery and traffic systems, the output of the motor can be transmitted to the machine using a simple mechanism. At the same time, adhesion of iron powder is reduced and durability of the machine is not impaired. Further, the motor can be installed under any temperature condition. For this purpose, a stator frame (4) is provided with a hub (5), a stator winding (7) is mounted on the outer periphery of the hub (5) via a yoke (6), a rotary shaft (12) is rotatably supported by a hole (8) in the hub (5), the rotor frame (13) is held at the outer end of the rotary shaft (12), and a rotor winding (14) possessed by the rotor frame (13) is arranged on the side of the outer periphery of the stator winding (7).

摘要： In a rotating electrical machine, when a stator winding is wound in concentrated winding, an improvement in performance is achieved by reducing a magnetomotive force harmonic without reducing a fundamental wave magnetic flux generated by a stator. A rotating electrical machine (10) includes a rotor (18), and two stators (14, 16) opposed with the rotor (18) being interposed therebetween either on both sides of the rotor (18) in the axial direction or on both sides of the rotor (18) in the radial direction. Stator windings (22) provided in a plurality of portions in the circumferential direction of each stator (14, 16) are wound in concentrated winding. The directions of magnetic fluxes generated by stator windings (22) having the same phase in the stators (14, 16) are in mutually opposite directions with respect to either the axial direction or the radial direction. The stator windings (22) having the same phase in the stators (14, 16) are arranged to be shifted from each other by 180 degrees in electrical angle in the circumferential direction.

摘要： The invention relates to a vehicle with an electronic driving engine and a power supply, especially a lift truck, with a power supply voltage of less than 96 volts. The driving engine is an asynchronous engine comprising a rotor provided with rotor plates and a stator provided with stator plates and more than four poles. In order to create a maintenance-free driving engine for vehicles, especially lift trucks, the driving engine should have more than 54 grooves in the stator plates and the root-mean-square value of the engine should be lower than 60 volts alternating current.
