摘要： The present invention belongs to the technical field of alternating current induction servo motors, and particularly relates to a rotary-type induction servo motor with a constant-output-torque by using uniform magnetic fields and a linear-type induction servo motor with a constant-output-force by using uniform magnetic fields. The present invention has main features that the rotary-type induction servo motor or the linear-type induction servo motor is composed of N independent motor units; each independent motor unit has the same or similar structure, and is powered by single-phase alternating current; and the N independent motor units have an equal voltage magnitude of power supply, but voltage phases are different and form an arithmetic progression. In an independent motor unit of the rotary-type induction servo motor with a constant-output-torque by using uniform magnetic fields, the stator magnetic conductive silicon steel is simple in structure, and the winding manner of stator excitation windings is simple, similar to a multilayer solenoid type; rotor induction excitation windings are powered through induction, and no slip ring and related wearing parts are used. The rotary-type induction servo motor disclosed here can be operated at fixed voltage frequency, and in this case, the output torque and the voltage magnitude of power supply are in direct proportion, so the output torque can be controlled by adjusting the voltage magnitude. The motor does not adopt permanent magnetic materials, and has many merits including simple structure, good torque characteristic, simple controller design and high control precision. And meanwhile, based on the same principle, a linear-type induction servo motor with a constant-output-force by using uniform magnetic fields can be evolved from the rotary-type induction servo motor.

摘要： An apparatus includes a housing, a crucible disposed in the housing, and a collection bin. A turnplate disposed in a powder collection area is of an inlaid structure. A concentric circular groove is provided on the atomization plane. An air hole is provided in the turnplate. The present invention combines the pulsated orifice ejection method and the centrifugal atomization method, in cooperation with the turnplate structure and subjecting the turnplate surface to induction heating, so that a metal liquid is allowed to break through the split mode of traditional molten metal, achieves a fibrous split mode that can be implemented only when an atomizing medium is an aqueous or organic solution, and prepares a high-melting-point metal powder that meets requirements, and has a controllable particle size, high sphericity, no satellite droplets, and good flowability and spreadability, and is suitable for industrial production.

摘要： An apparatus for efficiently preparing spherical metal powder for 3D printing includes a housing, a crucible and a powder collection area arranged in the housing, wherein a turnplate arranged in the collection area is an inlaid structure. A material having a poor thermal conductivity is selected as the base of the turnplate, and a metal material having a wetting angle less than 90° with respect to droplets is selected and embedded into the base to serve as an atomization plane of the turnplate. An air hole is disposed in the turnplate. The spherical metal powder for 3D printing combines electromagnetic force breaking capillary jet flow and centrifugal atomization, which breaks through the traditional metal split mode, and makes the molten metal in a fibrous splitting.
