potential field of application for magnetic encoder sensors
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!
Basically we are trying to find out, if e-bikers encounter any problems concerning the drivetrain of their e-bikes. This could possibly be: need of calibration of the sensors/motor after change of the chain/tyre, vulnerability against dirt and therefore necessity of cleaning exchanging the sensors...
So if you could think of any problem concerning the drivetrain when using your e-bike, please let us know
Custom-built ebikes usually are throttle-based without sensors in the drive system.
Commercial ebikes usually meet top-speed requirements by sensors or just by having a small motor. Commercial systems are usually well sealed and I've never heard of anyone having sensor-based issues with their ebikes (well, except for BionX owners wanting to disable the assist limit).
