Controller characteristics 1) the use of powerful intelligent microprocessor STM32, realize the field oriented control (FOC). The drive motor in pure sine wave mode, and accelerate the operation process more smoothly, lower noise. 2) reserved communication interface, users can upgrade the software of the controller version and change the parameter settings. 3) for flow controller, motor overheating, motor phase, battery voltage, communication signal failure and other abnormal conditions, with alarm and protection function. 4) 3 working modes: economy mode BOOST mode of protection 5) CAN bus, reverse charging, self detection, idle power, energy feedback and other functions 6) support custom function module. The powerful processing system equipped with 32 bit microprocessor control chip High power driver - 18 tube imported large MOS tube The precise orientation control of sine wave magnetic field oriented control (FOC) Product function And under voltage protection - motor over-current protection - motor over temperature protection - motor stall protection Capacitor pre charging controller Self - protection controller Over temperature protection controller Anti speed protection The energy feedback controller. The brake power-off protection and so on.
