Posted in Transportation Hacks Tagged AC synchronous motor, motor Post navigation We have, however, seen builds of reluctance motors that don’t use magnets. If you build your own motors, have you tried anything like this? Usually, we don’t see motors this big, of course. The company plans to offer a 400 V version of the motor and an 800 V that uses silicon carbide electronics. ![]() That means fewer seals and the ability to cool the rotor with oil as you would with a motor containing permanent magnets. However, ZF claims their inductive improvements are even more efficient and can reduce axial size by around 90 mm.Īnother advantage of the technology is that there is no need to provide a dry space for slip rings. To maximize efficiency, conventional SESM uses slip rings or brushes to transmit power to the shaft. The company claims the motor reduces losses by about 15% over conventional techniques. This kind of motor is usually destined for electric vehicles. The innovation here is that the inductive excitation is built completely into the shaft, which the company claims makes the motor both compact and powerful. This DC is often supplied by slip rings or an AC induction with a rectifier. Motors that employ SESM tend to be larger and require a direct current to turn the rotor. A technology called SESM (separately excited synchronous motors) requires no magnets, but now ZF - a German company - claims to have a different scheme using inductive excitation. But magnets are heavy, and good magnets can pose problems when you need lots of them. (For larger diameters, this can lead to overruns).When you think of electric motors, you usually think of magnets. The amount of excess does vary a lot between the diameters of the channels.īecause most air ducts that are cleaned are below 250 millimetres, we advise to always keep between 30 and 50 millimetres excess. In this way, you ensure that friction occurs and the bristles of the brush actually come into contact with the dirt. In order to clean the air ducts properly, a brush should always be larger than the duct itself. So, for example, you enter the channel clockwise and exit the channel counterclockwise. Because you tackle pollution from multiple sides. Turning both left and right improves the cleaning effect enormously. Not only is this easier to clean, it is also a lot more effective. This allows you to turn both left and right without losing the brush. Our FPDS shafts and FPDB brushes work with a unique socket connection. This can be a problem if you have a lot of parkers in the canal. As soon as you turn counterclockwise, the brush may become loose in the channel. The only drawback is that you can only turn clockwise. This is easy, simple and works on almost everything. These have a stronger nylon hair system, which scrapes the channels clean oversized. In case of harder soiling we advise to use heavier brushes, here you should think of our Spider Brushes. ![]() This is used in combination with a power drill shaft such as an ecoflex. In some cases one also suffers from heavier contaminants, which may be caked.įor 95% of the cases you can use a Nylon brush forward, so both the PDB and FPDB brushes are very common to use. ![]() Most air duct cleaning involves loose dust, which is usually quite soft in nature. Not only the material of the brush is important, but also things like the right excess for the channel.
