Abstract: A printing control method, storage medium, and a 3D printing device, applicable in a multi-supply automatic switching extrusion apparatus, includes: if a supply replacement signal is acquired, identifying a target feeding channel corresponding to the supply replacement signal; controlling a supply corresponding to a current feeding channel to return to a set position, and while the supply corresponding to the current feeding channel is returning to the set position, cutting off an end portion of the supply corresponding to the current feeding channel; and controlling an end portion of a supply corresponding to the target feeding channel to move to a printhead of a 3D printer, thus allowing the 3D printer to continue to execute a printing action. The present invention implements the automatic switching of multiple supplies without requiring manual operation and ensures that blocking and jamming of a supply are avoided when the supply is used again.

Abstract: The application relates a brushless motor and a rotor thereof. The rotor of the brushless motor comprises a rotor core, multiple first magnets for generating first magnetic fields in a radial direction of the rotor core, and multiple second magnets for generating second magnetic fields in a tangential direction of the rotor core; and the multiple first magnets and the multiple second magnets are alternately arranged one by one in a circumferential direction of the rotor core, so that the first magnetic fields and the second magnetic fields are mixed to form a hybrid magnetic field. The rotor can reduce electromagnetic noise of the motor and provides a counter electromotive force with better sinusoidal degree, which can satisfy requirements of FOC drive, reduce the cost of the motor, improve the performance of the motor, and reduce the weight of the motor.
