Description

technical field [0001] The invention relates to the field of special motor control, in particular to a current control device for a three-degree-of-freedom motion permanent magnet spherical stepping motor. Background technique [0002] With the adjustment and optimization of the product structure of small and medium-sized motors, special-purpose motors have become the focus of the development of the motor industry. As a novel special motor, the three-degree-of-freedom permanent magnet spherical motor has incomparable advantages in multi-degree-of-freedom sports. At the same time, the structure of different spherical motors, the distribution of stator coils and rotor magnetic poles have brought new difficulties to the energization control of spherical motors. [0003] The permanent magnet spherical stepping motor has a large number of stator coils, and each coil requires separate power control. The traditional motor control device is no longer suitable for the permanent magn...
