Advantages of Magnetic Piece Piece in Electric Power Tools

CJC has managed to launch an innovation by replacing the traditional magnetic ring with a magnetic piece in the BLDC motor. This transformation catapults overall performance, achieving an incredible 85% efficiency without the driving board and a remarkable 80% efficiency with the driving board. Beyond energy savings, this innovation champions sustainability, offering an eco-friendly solution for your power tool motors.

  • Improved Efficiency: The use of discrete magnetic pieces allows for more precise control over the magnetic field within the motor.Example: In a traditional magnetic ring setup, there might be some inefficiencies or magnetic losses. By using individual magnetic pieces strategically placed in the rotor, it becomes possible to optimize the magnetic flux, reducing losses and improving overall efficiency. This enhanced efficiency can lead to benefits such as lower energy consumption and reduced heat generation.
  • Reduced Cogging Torque: Cogging torque refers to the non-uniformity in torque experienced by the motor as it rotates. It can cause vibrations and affect the smoothness of motor operation.Example: The traditional magnetic ring design may contribute to cogging due to its continuous nature. When replaced with discrete magnetic pieces, the irregularities in the magnetic field that contribute to cogging can be minimized or better controlled. This reduction in cogging torque results in smoother motor operation, especially at low speeds, which is crucial in applications where precise control and low vibration are essential, such as robotics or electric vehicles.

Drive Design Enhancements for Power Tool Motors

  • Adoption of an External Driving Board: This not only optimizes internal space but also yields a compact yet powerful solution for electric power tools.
  • Double-Layer Drive Plate: Strategically designed fan blades contribute to efficient heat dissipation, preventing overheating during prolonged use and ensuring an extended lifespan for the motor.
