Development of a speed motor controller for applied physics research of spinners
The project includes the design of a drive system which, based on two electrically commutated DC motors and a time-discrete control, can set a disc of different diameters into precise rotations in the low hertz range. Furthermore, a waterproof housing and a circuit board are to be designed. The system is free-floating in a liquid during operation. This design makes it necessary to compensate the torque of the drive motor on the carrier board by an appropriate counter-rotation. By an individual control of the single windings of the DC motors, a vibration-free operation will be achieved. Furthermore, wireless communication for monitoring sensor data and the battery status, as well as the control of rotation direction and speed, is to be set up.
