A brushless DC motor with the magnetic modulation type differential resolver (MMD resolver) has been proposed. The MMD resolver is unique, and is constructed of 4 sensor coils in the stator. We have presented characteristics of resolver and the open loop performance of motor based on a voltage controlled drive system using lead angle control.<br>Because of the motor structure with the MMD resolver, several motor parameters should be treated as the function of rotor angle and also the mathematical model of the motors should be written in state equations.<br>There are few reports mentioning closed loop speed control using this type of motors. So we constructed a speed feedback loop using the MMD resolver signals and evaluated its performance by the original simulation program written in state equations instead of transfer functions, because of their non-linear structures.<br>And we made a simple real time estimation method of armature currents by inserting the voltage equations of this motor into the speed control programs and solving them simultaneously with the execution of speed control programs. By comparison between the results of measuring and the simulation, and also the currents of estimation and the measuring, we pointed out that motor parameters, motor model, structure of control model and control parameters were appropriate.<br>And we designed the MMD resolver waveform (magnitude and phase) correction methods to decrease signal error which was generated by special rotor magnet added to produce Z signal function.<br>We got relatively precise speed feedback signals from them and pointed out that this motor could be used as a speed control motor to use these correction methods.
