Unveiling the Conical Rotor Motor’s Unique Features

In the realm of electric motors, the conical rotor motor stands out, boasting characteristics that set it apart from conventional squirrel-cage rotor motors. One of its defining features is the integration of an inherent braking device. When energized, the rotor undergoes axial advancement, guided by the axial magnetic field. This movement triggers the opening of the built-in braking device, ensuring a swift cessation of rotation upon power disconnection. Widely embraced in industries like construction and metallurgy, this motor proves especially valuable in specialized environments and mechanical setups requiring rapid braking, such as automated control assembly lines.

Overcoming Manufacturing Challenges

The uniqueness of the conical motor, with its tapering stator inner bore and rotor outer diameter, poses manufacturing challenges. Traditional processes, involving large-tonnage punch presses, lead to issues such as low precision, inconsistent slot widths, and poor concentricity. Mold adjustments become intricate, resulting in various complications, including protrusion heights exceeding 0.05mm, uneven laminating, and difficulties in achieving mass production.

Innovative Solutions: The Stamping Production Revolution

To address these challenges, a cutting-edge stamping production line has been meticulously designed for the conical motor’s stator-rotor. This highly efficient line streamlines the manufacturing process, allowing for one-step molding, mass production, and ensuring high stamping accuracy while being energy-efficient.

Components of the Stamping Production Line

The core of this revolutionary production line comprises:

  1. Dual-Head Material Rack: Holds the coiled silicon steel strip, facilitating efficient material handling.
  2. S-Type Straightening Machine: Ensures the silicon steel strip is properly aligned before further processing.
  3. NC Feeder: Enables multi-stage feeding, feeding the strip into the high-speed punch press with progressive dies.
  4. High-Speed Punch Press with Progressive Dies: The powerhouse of the operation, achieving one-time stamping and blanking of stator-rotors of various sizes.

The Stator-Rotor Stamping Process

The integration of the NC feeder and progressive dies for multi-stage feeding is crucial. The feeding pitch is meticulously set for each station, ensuring precision throughout the process. The result is the production of stator-rotors with excellent consistency in usage. The slotted stator outputs uniform slot widths, protrusion heights below 0.02mm, high smoothness, minimal swelling, and a substantial reduction in excitation current and eddy current losses.

Benefits of the Stamping Production Revolution

The advantages of this innovative manufacturing approach are far-reaching. Stator-rotors produced in a single stamping exhibit not only excellent consistency but also contribute to increased power output. The high precision and quality of the process significantly lower manufacturing costs, enhance operational convenience, and maximize applicability to mass production.

In conclusion, the conical rotor motor, coupled with this advanced stamping production line, marks a paradigm shift in the industry. Embracing innovation, precision, and efficiency, it paves the way for a new era in the manufacturing of electric motors, meeting the demands of diverse industries and ensuring optimal performance in specialized applications.
