    Hi everyone

    please can any one give me an idea about what's a gimbal brushless motor , is it a normal bldc or a stepper motor ?

    if it's bldc, how can they control it accurately without hall sensor??, is the control feedback by the gyro and the accelerometer? how ?


    I wish you can help me

    thanx

    Both could exist. It depends on the application. I believe the word 'gimbal' describes the application, not the motor type. Everyone is interested in GoPro cameras and a stabilizer gimbal.

    This one appears to be BCD. http://m.youtube.com/watch?v=hEWLrnYxLl0

    A gimbal is just another name for a pivoted mount for the motor or mechanism.
    A BLDC motor just uses the hall sensors or equivalent tracks on an encoder for commutation, not positioning.
    For position you need a encoder or resolver or similar device.
