    How to characterize the BLDC?

    Hello, I want to simulate the control system for the BLDC, but I don't know how to characterize the BLDC based on the torque-speed curves? The BLDC model has a lot of parameters, such as l,r,ke(backemf constant), kt(torque constant), j(inertia). How can get them from bhe torque-speed curve...

    The safe angular velocity for the direction reversal

    Hi, I know when I want to change the rotating direction of a Brushless DC motor, I have to wait until its speed drops down to slow speed near zero. I'd like to know if the data sheet of the BLDC will give me this information? what is the safe speed for the direction reversal? Thanks, tcad

    How to control the 3-phase brushless dc motor?

    Hello, I have some questions about the 3-phase brushless dc motor. Could you give me some help? Thank you very much. I know there are two different control method for the 3-phase brushless dc motor, one is the sensorless DSP control and one is to use the hall position sensor. I'd like to know...

    How to change the direction of Brushless DC motor

    Hi Nbucska, Thanks a lot for your quick response. So based on you reply, it is difficult to use the brushless dc motor in the applicition of position control and also the application of closed-loop speed control in which the direction will change frequently. Is my understanding right? Thanks...

    How to change the direction of Brushless DC motor

    Hi guys, When I simulate the speed control of the Brushless DC, it is difficult for me to control the direction of motor dynamically. If I don't change the direction of the motor, the simulator works fine. but if I change the direction when the voltage is still high, the motor will oscillate and...

    How to characterize the DC_PM motor?

    Hi guys, I want to do some simulation on the application of the DC_PM motor, now I got a datasheet of the DC_PM motor, it gives out the curves of speed vs. torque, current vs. torque, and power vs. torque. but it doesn't give me the parameters the simulator required, such as the armature...
