1. Advantages of coreless motor

Coreless motor is a kind of DC permanent magnet servo micro motor. The main difference between the coreless motor and the ordinary motor is the use of iron core

Rotor/stator, also known as coreless rotor/stator.

Coreless motors have the following advantages:

• High energy conversion efficiency (the index to measure its energy-saving characteristics): the efficiency is above 70%, and some products can reach above 90% (ordinary core motors are between 15-50%);

• Quick start and brake, extremely fast response: the mechanical time constant is less than 28 milliseconds, and some products can reach less than 10 milliseconds.

The speed adjustment of the speed adjustment is sensitive in the recommended operating area.

• Reliable running stability: strong adaptability, speed fluctuation can be controlled within 2%;

• Less electromagnetic interference: high-quality brushes, commutator structure, commutator sparks are small, which can avoid additional anti-interference devices;

• High energy density: Compared with the same power core motor, its weight and volume are reduced by 1/3 to 1/2; corresponding parameters, such as speed-voltage,

Speed-torque, torque-current, etc. all present standard lines.
