What is the difference between a coreless motor and a brushless DC motor?

1. Different structures

1. Coreless motor: A servo and control motor of a DC permanent magnet, which can also be classified as a micro motor. The coreless motor breaks through the rotor structure of traditional motors in terms of structure, and adopts a coreless rotor, also called a coreless rotor. This novel rotor structure completely eliminates the power loss caused by eddy currents formed by the core.

2. Brushless DC motor: A brushless DC motor consists of a motor body and a driver, and is a typical mechatronics product.

2. Different principles

1. Coreless motor: A coreless motor breaks through the rotor structure of traditional motors in terms of structure, and adopts a coreless rotor, also called a coreless rotor. This rotor structure completely eliminates the power loss caused by eddy currents formed by the core, and at the same time, its weight and moment of inertia are greatly reduced, thereby reducing the mechanical energy loss of the rotor itself.

2. Brushless DC motor: A brushless DC motor consists of a motor body and a driver, and is a typical mechatronics product. The stator winding of the motor is mostly made into a three-phase symmetrical star connection, which is very similar to the three-phase asynchronous motor. The rotor of the motor is attached with a magnetized permanent magnet. In order to detect the polarity of the motor rotor, a position sensor is installed in the motor.

3. Different functional applications

1. Hollow cup motor: The application of hollow cup motor has developed rapidly in the past ten years after entering the large industrial and civilian fields from the military and high-tech fields, especially in industrially developed countries, and has involved most industries and many products.

2. Brushless DC motor: Brushless DC motors are widely used, such as automobiles, tools, industrial control, automation, and aerospace, etc.
