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 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 its incomparable advantages in multi-degree-of-freedom motion occasions. At the same time, the structure of different spherical motors and the distribution of stator coils and rotor magnetic poles have brought new problems to the energization control of spherical motors. [0003] The permanent magnet spherical stepping motor has a large number of stator coils, and each coil needs a separate energization control. The control device of the traditional motor is no longer applicable to...
