Is WEDM stepping motor strong or weak?

Strong magnetism. Stepper motors are all strong magnetic, and the higher the magnetic field strength, the better the performance and the stronger it can be, so manufacturers adopt neodymium magnets with high magnetic field strength. The inner rotor of stepping motor is a polar permanent magnet (which can be understood as a strong magnet), and several groups of coils are embedded in the stator. When some coils of a given stator are energized with current in a certain direction, a magnetic field in a certain direction will be formed inside the stator. Under the action of this magnetic field, the permanent magnet stator will be positioned according to the principle of N-S pole attraction. As long as the current of the external coil is changed to make the magnetic field generated by the stator rotate in a certain direction and speed, the rotor can rotate with the magnetic field of the stator.
