Abstract:
The invention relates to a method of producing a rotor (10) of an electric machine, the rotor (10) comprising a rotor body (14) adapted to be rotated about a rotor axis (A) as well as at least one rotor component (16) to be mounted to the rotor body (14), said method comprising the steps of: arranging the rotor component (16) on the rotor body (14) and winding a wire-like structure (20) around an outer circumference (12) of the rotor body having the rotor component (16) arranged thereon so as to form a bandage (18), with the wire-like structure (20) during winding thereof being held under an adjustable bias.
Abstract:
A drive system (DS) for a land craft comprises a machine system (M1, M2) for driving the land craft, the machine system comprising at least a first and a second electric machine (M1, M2) acting on a common drive shaft (S) for driving the land craft, and a control device (PE, PE1, PE2) which is adapted to control the machine system for operating in at least two rotating speed operation ranges (OR1, OR2) with different rotating speeds of the drive shaft (S). The first electric machine (Ml) is controlled to operate in both rotating speed operation ranges (OR1, OR2) to provide a first drive torque, and the second electric machine (M2) is controlled to operate in only one of the rotating speed operation ranges (OR1) to provide a second drive torque in addition to the first drive torque.
Abstract:
Die vorliegende Erfindung betrifft einen Rotor (10) einer permanentmagneterregten elektrischen Maschine (100), aufweisend eine Mehrzahl von Permanentmagneten (18), die eine Mehrzahl von Rotorpolen bilden, welche um einen an einen Luftspalt (102) der elektrischen Maschine (100) angrenzenden Umfang des Rotors (10) herum angeordnet sind, wobei die Permanentmagnete (18) als in einen Rotorkörper (16) eingebettete Permanentmagnete ausgebildet sind, wobei jeder Rotorpol zwei V-förmig zueinander angeordnete Permanentmagnete (18) aufweist, wobei jeder der beiden Permanentmagnete (18) jeweils einen Schenkel des V bildet, wobei die beiden Permanentmagnete (18) eines jeweiligen Rotorpols an einem vom Luftspalt (102) fernen Ende einander zugewandt sind und sich zu einem gegenüberliegenden dem Luftspalt (102) näheren Ende hin voneinander weg erstrecken, und wobei der Rotorkörper (16) wenigstens eine in den Luftspalt (102) mündende Ausnehmung (24) aufweist.
Abstract:
Wheel drive unit for attachment to an aircraft running gear, said wheel drive unit including a drive motor (22) or a drive motor (22) with subsequent transmission (24) and comprising the following features: a mounting component (10) adapted to be mounted to a supporting component of the aircraft running gear; a coupling component (14) releasably anchored to the mounting component (10) in non-rotatable fashion; the drive motor being supported by means of the coupling component (14) such that the coupling component (14) provides for torque support of the drive motor; a pluggable connection (60) for connecting at least one pair of electric line sections and/or at least one pair of fluid line sections; the torque output of the drive motor (22) or of the subsequent transmission (24) being adapted to establish a torque-transmitting connection to a wheel (8) of the aircraft running gear when the wheel drive unit is attached to the aircraft running gear; the wheel drive unit - without the mounting component - when the anchoring to the mounting component (10) is released, being demountable from the aircraft running gear which also separates the two parts of the pluggable connection (60) from each other.
Abstract:
An electric machine comprises a rotor (200) equipped with permanent magnets (204, 206, 208, 210), and a stator (100) equipped with electromagnetic poles. The electric machine is characterized in that several adjacent electromagnetic poles respectively constitute an electromagnetic pole group in which the adjacent electromagnetic poles are spaced apart at a first electromagnetic pole spacing, that adjacent electromagnetic poles belonging to different electromagnetic pole groups are spaced apart at an electromagnetic pole spacing greater than said first electromagnetic pole spacing, that each electromagnetic pole group has an even number of electromagnetic poles, and that adjacent electromagnetic poles of an electromagnetic pole group are linked to each other so as to generate magnetic fields of opposite direction in operation.
