@flecc Thank you for your reply. 1) A manufacturer of e-bikes recently mentioned that seniors in e-motors, which determine the position of the rotor face heat issues from time to time. Could this be a potential weak spot of sensors in e-motors? 2) You mention the problem with external magnetic fields...do these electro magnetic fields disturb the sensor itself or does it affect the transfer of the signal to the output device? If the problem occurs directly at the sensor, this could be prevented through applying our magnetic encoders, as they can not be influenced by external magnetic fields. 3) It also helps us a lot when e-bikers simply tell us, that there are no problems. We are, however, still trying to find out, if there are an issues which can be solved by our magnetic encoders. 4) Does this system have any weak spots, e.g. has to be cleaned very often, etc. Can you think of an problems with this system? @all Please let us know if you can think of an further problem, concerning the sensors applied in e-bikes.

Dear all, In the course of a project headed by the University of Business and Economics Vienna, we are looking for potential application fields of a magnetic encoder. Basically the technology allows measuring the position of a magnet. Can you imagine a field, where for instance one or several of the following problems occur; • Positions have to be measured contactless • Extreme external conditions (dust, other magnetic fields, temperature, vibrations) have to be passed over • Maintenance is difficult due to the high complexity of the final product/application • Linear, rotating or three-dimensional positions have to be measured • The space is limited and expensive • It is vivid to avoid/know about malfunctions of position tracking systems • Easy implementing and catch/use of the signal is necessary • An energy effective solution is important. We were able to identify the drive system as a potential field of application. To be precise, the sensors, which control the power of the electro motor, show (according to various interviewees) several weak spots. This could be e.g.: imprecise responding behaviour of the sensors which prevents the driver from controlling the e-motor properly, necessity of calibrating the sensors after change of tyre or chain, sensors which are heavily affected by dirt an therefore have to be cleaned or exchanged regularly, usage of antiquated gearshift equipment… Please let us know if you experienced any of the above mentioned or other problems in the past. It would be of great help for us! Thank you very much!
