摘要： A system for driving a drum includes a pulse motor including an annular rotor fixedly mounted within the drum for rotation therewith and rotatable relative to a stator disposed within the rotor. The pitches of the rotor teeth and stator teeth are determined in such a manner that a magnetic flux linking each of the coils is changed in a sinusoidal fashion in synchronism with the rotation of the rotor. A pole position-detecting device produces a multi-phase sinusoidal pole position-detecting signal representative of the position of the magnetic poles relative to the rotor. A speed control device produces a current amplitude command signal representative of a desired torque of the rotor. A multiplier multiplies the pole-position detecting signal by the current amplitude command signal to produce a multiplication signal. A current control device is responsive to the multiplication signal to output to the coils a drive current corresponding in amplitude to the current amplitude command signal and corresponding in phase to the pole-position detecting signal, thereby energizing the coils to rotate the rotor together with the drum relative to the stator.
