What’s the features and advantages of Coreless Motor Hollow Cup Motor?

The hollow cup motor (eg. Coreless Motor) is a DC permanent magnet and servo micromotor. The main difference between the hollow cup motor (Coreless Motor) and ordinary motor is the adoption of an iron core rotor/stator, also known as the hollow cup rotor/stator.

The hollow cup motor has the following advantages:

Large energy conversion efficiency (a measure of its energy-saving characteristics) : its efficiency is above 70%, and some products can reach above 90% (ordinary core motors are between 15-50%);
Quick activation and braking, and extremely fast response: 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 running area.
Reliable operation stability: with strong adaptive ability, its speed fluctuation can be controlled within 2%;
Less electromagnetic interference: quality brush, commutator structure, small commutator spark, 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;The corresponding parameters, such as rotational speed – voltage,rotational speed – torque, torque – current, etc. all present standard lines.
