II. Product Introduction

Hollow cup motor belongs to DC permanent magnet and servo micro-special motor. The main difference between hollow cup motor and ordinary motor is the use of coreless rotor and stator, also known as hollow cup stator and rotor.
Maximum energy conversion efficiency (an indicator of its energy-saving characteristics): Its efficiency is generally over 70%, and some products can reach more than 90% (ordinary iron-core motors are 15-50%).
Activation, braking speed, response is very fast: mechanical time constant is less than 28 milliseconds, some products reach less than 10 milliseconds, in the recommended high-speed operation area, speed regulation is sensitive.
Reliable operation stability: strong adaptive ability, self-speed fluctuation can be controlled within 2%.
Low EMI: High-quality brushes, commutator structure, small commutation spark, can avoid additional anti-interference devices
High energy density: Compared with iron core motors with the same power, their weight and volume are reduced by 1/3-1/2; the corresponding parameters of speed-voltage, speed-torque and torque-current all show standard linear relationship.
