AC variable frequency controller

AC variable frequency controller
Introduction
DM Series electric vehicle AC inverter motor drive controller uses an advanced vector control mode and voltage space vector pulse width modulation technology, not only to achieve the low-speed large torque motors and high-speed constant power operation, but also effective use of the battery voltage, reduce motor harmonics, reduce the torque ripple and reduce the switching losses.
A "full-digital AC motor control technology", DM series of AC variable frequency motor drive controller's core is comprised of 32 dedicated motor control DSP chip, and intelligent power MOSFET devices composed of the motor provides a smooth, no noise, and efficient performance.
Apply
DM Series electric vehicle AC inverter motor drive controllers are widely used in electric cars, golf carts, electric sightseeing cars, electric hunting cars, trucks and other heavy-duty electric vehicles.
Features
* Advanced vector control technology can achieve low-speed large torque, high-speed constant power operation, effective use of the battery voltage, reduce motor harmonics, reducing the torque ripple and reduce the switching losses. High-performance real-time estimates of motor torque and power, can change in a wide to maintain high efficiency under the conditions of optimum operating condition. For 48V battery-powered systems, the exchange peak current of 300A ~ 600A.
CAN communication protocol to achieve an integrated whole to the distributed control system of communication; for vehicle running state data show, the battery management system for control and vehicle controllers.
