Principle, Structure, and Product Advantages of Coreless Motors

Due to the structural breakthrough of coreless motors, which adopt a rotor without an iron core, also known as a coreless rotor, they completely eliminate power loss caused by eddy currents formed in the iron core. Hence, they are called coreless motors.

By overcoming the technical barriers that traditional iron-core motors struggle to surmount, coreless motors exhibit outstanding characteristics in their primary performance, offering a wide range of applications. Especially with the rapid advancement of industrial technology, the increasing expectations and requirements for motor servo characteristics have made coreless motors irreplaceable in many applications.

Working Principle of Coreless Motors:

Coreless motors break through the traditional rotor structure by adopting a rotor without an iron core, also known as a coreless rotor. This innovative rotor structure completely eliminates power loss caused by eddy currents formed in the iron core. Additionally, it significantly reduces rotational inertia, resulting in fast response speeds, excellent control characteristics, and superior servo performance.

Product Features of Coreless Motors:

1) Energy-Saving Characteristics: High energy conversion efficiency, typically above 70%, with some products reaching up to 90%.

2) Control Characteristics: Rapid starting and braking with extremely fast response times. The mechanical time constant is less than 28 milliseconds, and some products can achieve response times within 10 milliseconds. In high-speed operation within the recommended working range, the motor allows for sensitive and precise speed adjustments.

3) Dynamic Characteristics: Highly reliable operational stability with minimal speed fluctuations.
