Wherein, the frequency converter is used to connect the drive motor of the electric vehicle, and the controller 4 controls the output speed of the drive motor of the electric vehicle through the frequency converter in a vector control mode; the regulator 5 is fixed on the housing The filter 7, the electric signal amplifier 8 and the A/D converter 9 in 6 are sequentially connected to form a structure; the filter 7 is electrically connected to the signal output terminal of the tachometer; the A/D converter 9 is connected to the controller's Signal input terminal electrical connection.
本技术方案的特点是在电机的输出轴上设置测速仪，通过测速仪来监测电动车车轮转速的大小，并将实时监测到的信号通过调整器传输给控制器，所述控制器通过矢量控制的方式通过变频器控制电动车驱动电机的转速，进而实时调整驱动电机的输入功率，使电机得到与其即时负载最相适应的电压，降低电能损耗，提高电能的利用率，延长电机的使用寿命。The feature of this technical solution is that a speedometer is installed on the output shaft of the motor, and the speed of the electric vehicle wheel is monitored through the speedometer, and the real-time monitored signal is transmitted to the controller through the regulator, and the controller is controlled by vector The method controls the speed of the electric vehicle drive motor through the frequency converter, and then adjusts the input power of the drive motor in real time, so that the motor can obtain the voltage that is most suitable for its immediate load, reduce power loss, improve the utilization rate of power energy, and prolong the service life of the motor.
在本技术方案中，控制器通过测速仪检测电动车车轮转速的大小，从而根据电动车车轮转速的大小来实时调整驱动电机的频率和电压，控制驱动电机输出轴的转速。In this technical solution, the controller detects the speed of the wheel of the electric vehicle through the speedometer, thereby adjusting the frequency and voltage of the driving motor in real time according to the speed of the wheel of the electric vehicle, and controlling the speed of the output shaft of the driving motor.
在本技术方案中，给驱动电机输入的电功率被转换成为电动车车轮转动需要的机械出力和电机自身的损耗两部分。驱动电机自身的损耗又由磁铁的「铁损」、导线的「铜损」及轴承摩擦、风扇的机械损组成。控制器通过测速仪检测电动车车轮转速率的变化，根据负载的实际需求，实时调整电机的输入功率，保证电机在最小电流和最佳电压的节能状态下运行。电机电流和电压的最小化就可以使电机自身的「铁損」和「铜损」减到最小，实现在节能运行的同时减少电机的发热，并大大延长电机的使用寿命。In this technical solution, the electric power input to the drive motor is converted into two parts: the mechanical output required for the wheel rotation of the electric vehicle and the loss of the motor itself.

The controller detects the change of the rotation rate of the electric vehicle wheel through the speedometer, and adjusts the input power of the motor in real time according to the actual demand of the load, so as to ensure that the motor runs in an energy-saving state with minimum current and optimal voltage. The minimization of motor current and voltage can minimize the "iron loss" and "copper loss" of the motor itself, realize energy-saving operation while reducing heat generation of the motor, and greatly extend the service life of the motor.
