Why are coreless motors more and more popular?

Coreless brushless motors are becoming more and more popular in our daily applications such as power tools, medical equipment, air conditioners, robotics, precision instruments, aerospace, electric vehicles, white goods and industrial applications, etc. It makes electronic equipment more reliable and durable. Why is the hollow cup brushless motor more and more popular in the market? Next, Vistar Micromotor will analyze the reasons why the hollow cup motor is popular in the market.

1. The first major advantage of brushless motors is efficiency. Because a brushless motor can rotate continuously at its maximum rotational force (torque), in contrast, a brushed motor can only provide maximum torque at certain points of rotation. While a brushed motor can provide the same torque as a brushless motor, a brushless motor requires more magnetism, which means that a smaller size brushless motor can provide a fair amount of power.

2. Another advantage of the hollow cup brushless motor is the controllability, the feedback system can be used to control the hollow cup brushless motor to provide the required torque and speed. If the coreless brushless motor is battery powered, this precise control can reduce energy consumption and heat loss, and help extend battery life.

3. The hollow cup motor has high durability and low electrical noise. For brushed motors, the brushes and commutators wear out due to continuous motion contact, which may produce sparks. In particular, these sparks are usually generated when the brushes pass through the commutator gap, and strong sparks can cause electrical noise.
