In the field of modern electronic equipment and machinery, brushless motor and coreless motor are two common types of motors. They each have unique performance advantages and are widely used in different industrial and consumer electronic products. From power tools to drones, from robots to household appliances, the use scenarios of these two motors are very wide. So, what are brushless motors and coreless motors? What is the difference between them? In this article, X-TEAM editor will introduce the characteristics and applications of these two motors in depth.

Brushless motor and coreless motor: comparison and application of two motor technologies

  1. What is a brushless motor?

A brushless DC motor (BLDC) is an electric motor that uses electronic control to replace traditional brushes. The working principle of this motor is based on electromagnetic induction, and the direction of the current is controlled by an electronic commutator to achieve the rotation of the motor. Compared with traditional brushed motors, brushless motors have higher efficiency, longer service life and lower noise. It does not require mechanical brushes for current conduction, thus avoiding the wear problem of brushes and commutators.

The main advantages of brushless motors are:

High efficiency: Since there is no brush friction, the conversion efficiency of electrical energy is higher.

Low noise and low maintenance: The brushless design reduces friction noise and maintenance requirements.

Long life: Reduced brush wear extends the life of the motor.

High-precision control: Brushless motors can be precisely adjusted through precise electronic control systems.

 

  1. What is a coreless motor?

A coreless motor is a specially designed brushless motor whose rotor has no iron core, hence the name “coreless”. Compared with traditional motors, the rotor of a coreless motor adopts a lightweight design, which can significantly reduce inertia and power consumption during rotation. This makes the coreless motor particularly outstanding in terms of response speed and control accuracy.

The main features of the coreless motor include:

Lightweight design: The coreless rotor makes the motor lighter and suitable for applications with strict weight requirements.

High speed and high efficiency: Because the rotor has no iron core, the motor responds faster and is more efficient.

Low inertia: The lightweight rotor allows the motor to change speed more quickly, suitable for high-precision, high-frequency control applications.

Suitable for small devices: Due to their small size and light weight, coreless motors are often used in micro devices and portable tools.

 

  1. Differences between brushless motors and coreless motors

Brushless motors and coreless motors have similar working principles. Both are brushless designs and rely on electronic commutators to control current. However, there are some significant differences in their structure and performance.

1) Structural differences:

Brushless motors: Traditional brushless motors usually use rotors with iron cores. Although they can increase the magnetic field strength of the motor, they are also relatively heavy and suitable for medium and large equipment.

Coreless motors: The rotors of coreless motors have no iron core, so they are lighter and suitable for equipment with strict requirements on weight and inertia.

2) Application scenarios:

Brushless motors: Due to their high efficiency, long life and low maintenance, they are widely used in power tools, electric vehicles, drones, household appliances and other fields.

Coreless motors: Due to their advantages of light weight and high speed, coreless motors are mostly used in fields that require high-precision control, such as micro robots, drone servos, electric toys and high-precision instruments.

3) Performance:

Brushless motor: It can provide continuous and stable power, suitable for high-power and long-running equipment.

Coreless motor: Because there is no iron core, the rotation inertia is small and the response speed is fast, which is suitable for small equipment and applications that require fast speed adjustment.

 

  1. Choice of brushless motor and coreless motor

Choosing a brushless motor or a coreless motor depends on the specific application requirements. If a device requires high power and long-term stable operation, choosing a brushless motor is an ideal choice. For small devices that require lightness, fast response and high precision, coreless motors are more suitable.

For example, brushless motors are widely used in electric vehicles, drones, home appliances and other fields, while coreless motors are more used in remote control toys, precision instruments and robotics.
