Product features: Same frame, different cores: IEC has the same external installation dimensions, but comes with a super strong magnetic field, providing high efficiency, energy saving, and stable power output. Ultra high efficiency: super strong magnets and higher slot filling rate winding process, combined with high-grade low iron loss silicon steel sheets, achieve ultra-high motor efficiency, and the overall efficiency of the drive is higher than 90%. High speed response: adopting an 8-pole or 10 pole or higher rotor design, and using super strong neodymium iron stone, achieving high-speed dynamic response and low torque fluctuation. Adopting a sinusoidal rotor magnetic field design, reducing pulsating torque, achieving smooth torque output, reducing noise, reducing speed fluctuation, improving position accuracy, more suitable for mechanical processing, tension control and other fields. High reliability: Using high-quality materials, especially since Volcano has its own neodymium iron boron production factory, can ensure the quality of core materials and avoid the most fatal demagnetization problem of permanent magnet motors. Moreover, the motor can be vacuum sealed, which not only effectively solves internal heat dissipation, but also avoids motor burnout caused by enamel wire peeling due to magnetic vibration caused by opposite current direction.
