50-200kw EV Drive Motor Dvac Controller Inverter for Electric Car Bus

The motor controller is suitable for 50-200KW permanent magnet synchronous motor and AC asynchronous motor control. It adopts an advanced vector control algorithm and can be used for driving and other control systems of buses, minibusses, commercial vehicles, and passenger cars, etc. The controller adopts CAN bus communication technology.

·Using powerful automotive-grade microprocessor
·Patented direct water-cooled automotive-grade IGBT power module
·High efficiency, high power density
·Easy installation, beautiful appearance, small size, lightweight
·Advanced vector control technology
·Anti-electromagnetic interference, strong anti-vibration
·Perfect protection mechanism
·Very wide torque and speed control range
·With torque control mode, speed control mode, and brake power regeneration function
·Speed control and torque control mode, control accuracy within 3%
·Appropriate temperature control algorithm, the ambient temperature range where the controller can work: -40~85ºC
·Battery protection function: when the battery voltage is low, it will alarm and limit the current in time, and stop the output when it is too low to protect the battery
·With temperature protection function: when the temperature is too high, it will automatically limit the current and reduce the power to protect the controller and the motor. When the temperature rises uncontrollably, the controller will automatically cut off to protect the motor, and the controller
