Abstract: Taking the Lorentz motor for example, a motor drive with the characteristic of bandwidth of 3 kHz and current accuracy up to 0.1mA was studied. Base on the analysis of the principle and mathematical model of the Lorentz motor, the motor drive was studied including current regulation circuit, Hbridge drive circuit, LC filter circuit and the current feedback circuit. Simulation in frequency domain and experiments in time domain were also presented.
