Abstract:
The invention relates to a synchronous motor (1), in particular for battery operated vehicles, and a method for the operation thereof. The synchronous motor (1) according to the invention has a rotor having yoke elements (2, 3, 6), wherein the rotor comprises at least one first yoke element (2) carrying permanent magnets (5) and one second yoke element (3) which carries permanent magnets (5) and is opposite the first yoke element (2). According to the invention, a stator is (4) arranged between the first and second yoke elements (2, 3). At least one of the yoke elements (2, 3, 6) can be adjusted relative to the other yoke element(s) (2, 3, 6) such that the magnetic flux is altered. The adjustment is carried out in dependence of the rotational speed.
Abstract:
The present invention relates to a power-generating apparatus for an electric vehicle equipped with a power-generating means, wherein the power generating means comprises: a discoid conductive bar made of a conductive material through which electrical current can flow, and having a through-hole in the center thereof; a power-transmitting shaft inserted into the through-hole of the conductive bar to rotate together with the conductive bar, and dynamically connected to a drive wheel of the electric vehicle; and a cover provided with a magnet for forming a magnetic field to rotate the conductive bar via electrical power, disposed so as to enclose the conductive bar, and coupled in a rotatable manner with respect to the power-transmitting shaft, such that the rotational force of the conductive bar via the electrical power is transferred to the power-transmitting shaft in order to rotate the drive wheel.
Abstract:
A permanent magnet rotating electric machine has a rotor and a stator, one of the rotor and stator having thereon a plurality of permanent magnets, and the other having thereon a plurality of electromagnetic poles arranged to receive electrical windings. In addition to typical rotation of the rotor, the stator and rotor are movable relative to one another in an axial direction to cause a variation in the airgap between the permanent magnets and the electromagnetic poles. A phased current is applied to the electrical windings of at least one of the electromagnetic poles by way of electrical means. This phased current results in a variation of the magnetic field produced by the electromagnetic poles such that relative movement of the stator towards or away from the rotor can be magnetically controlled.
Abstract:
A rotary electrical machine comprising a stator (10) and at least one rotor (12) having a plurality of permanent magnets (14). The rotor consists of a rotor disc, at the outer edge of which the permanent magnets are mounted. The rotor disc (12) is provided with airgap varying means (19) which are angled towards the stator (10) and mounted on the rotor hub (24) for rotation therewith. When the rotor is stationary, the airgap (30) between the magnets (14) and the stator (10) is at a minimum. In operation, as the speed of rotation of the rotor (12) increases, a centrifugal force is generated which acts to bend the airgap varying means (19) and, therefore, the rotor disc (12) back, away from the stator (10), thereby drawing the magnets (14) away from the stator and increasing the size of the airgap (30). The increase in size of the airgap results in a corresponding decrease in flux and therefore a decrease in the maximum output voltage for that rotor speed. In this way, the output voltage of the machine is kept substantially constant. A stationary iron ring (32) may be provided on the stator (10) to assist in drawing away flux as the size of the airgap is increased.
Abstract:
A system to continuously and redundantly monitor a magnetic drive system includes temperature sensors coupled to the magnetic drive system. The temperature sensors are coupled to a transmitter, which generates output signals representing the temperatures of the temperature sensors. The system includes a transreceiver and a controller, where the transreceiver is coupled to the transmitter and configured to receive the output signals of the transmitter. The controller is communicatively coupled to the transreceiver and the magnetic drive system and is configured to control operation of the magnetic drive system based on one or more signals received from the transreceiver.
