Analysis of a Transverse Flux Machine with Regard to Operation of Energy Harvesting

摘要:

为了监测汽车电机的工作情况需要应用各类传感器，其中的挑战之一是为在旋转部件上布置的传感器提供电能。通过使用能量收集器，可以将电机中的寄生能量如电磁能和动能收集、转化为电能并储存，存储的电能可用来操作传感器。因此，本文以电机转子为重点，对一台横向磁通机进行研究，其中能量收集器用于收集足够的能量，并为一个温度传感器以及低功耗蓝牙非接触数据传输供电。为此，本文计算了当能量收集器被放置在横向磁通电机转子上时，在运行和生产过程中可望收集到的能量值。

Abstract:

Electric machines are replacing increasingly combustion engines as traction machine in modern vehicles. To monitor the behavior of the electric machines， sensors are needed. A major challenge is the electrical powering of the sensors on rotating parts of the machine. By using an energy harvester， parasitic energy from the electric machine， such as electromagnetic and kinetic， can be collected. The collected energy gets transformed into electric energy and used to power sensors. Additionally， a storage device can be integrated. To realize an energy harvester， a transverse flux machine has been investigated， focusing on the rotor of the machine. The goal for the energy harvester is to collect enough energy to power a temperature sensor with contactless data transfers via Bluetooth Low Energy. Therefore， the amount of energy that can be expected to be collected during operation and production when positioning the energy harvester on the rotor of the transverse flux machine is calculated.
