How much smaller is the volume of a brushless motor compared to a traditional brushed motor.

Is it beneficial for brushless motors to be smaller in size compared to traditional brushed motors.

At the same power, brushless motors are much smaller in size than brushed motors, and this difference gradually widens with increasing power, with the maximum difference reaching 30%.

So some customers also have doubts, what are the benefits of brushless motors being smaller in size than brushed motors? For the equipment with exposed motors, the factor affecting volume is indeed much smaller. But for some customers who need to install motors inside the equipment, volume is a primary consideration. Especially on some high-precision instruments, there are high precision requirements for the motor and certain volume requirements, so Topband miniature brushless reduction motor is the first choice.

The small size of Topband's brushless motors not only provides more choices for customers who have certain volume requirements when installing them inside the equipment, but also optimizes the structure of traditional machinery. Because many times, due to the volume problem of traditional brushed motors, concessions need to be made in other places when designing products to free up space for installing motors. The emergence of brushless motors can break this rule. Customers can minimize the obstacles caused by motor volume to the equipment during design and development, and make the structure of the equipment as reasonable as possible.
