储能飞轮由于其高储能密度、高寿命及高充放电次数而在能量储存系统中得到广泛重视。首先开发了以普通磁悬浮轴承支承、普通永磁无刷直流电机驱动和发电的FW-15A储能飞轮系统,用以验证高速磁悬浮支承系统的功能、制造安装,并分析储能飞轮系统的功耗。在FW-15A的基础上,开发出FW-15B系统,该储能飞轮系统侧重于降低功耗,采用新型永磁偏置径向和轴向磁轴承,采用杯形绕组永磁无刷直流电机。试验表明,在飞轮转子静止时,FW15-B和FW15-A的磁轴承功放输入功率分别为3.59W和29.6W;在25974r/min飞轮转速时,FW15-B和FW15-A的电机功放输入功率分别为10W和20W。
Energy storage flywheel due to its high storage density, high life and charge and discharge times in the energy storage system has been widely attention. Firstly, the FW-15A energy storage flywheel system driven by ordinary magnetic bearing, ordinary permanent magnet brushless DC motor and power generation was developed to verify the function, manufacture and installation of high-speed magnetic suspension system and to analyze the power consumption of the energy storage flywheel system . On the basis of the FW-15A, the FW-15B system has been developed. The energy storage flywheel system focuses on reducing power consumption. The new permanent magnet bias radial and axial magnetic bearings are adopted. The cup-wound permanent magnet brushless DC motor . The experimental results show that the input powers of the magnetic bearings of FW15-B and FW15-A are 3.59W and 29.6W when the flywheel rotor is stationary. The input power of the motor amplifier of FW15-B and FW15-A at 25974r / min flywheel speed Respectively 10W and 20W.
